Hi dzignr_tastz,

[quote]Now given those further excerpts (and specifically, the second example in the last section), I can only assume since foam undeniably makes up 95% of the final product in a mattress, if said foam (and probably the cover, to make up the last 5% - LOL) is indeed imported from China, then regardless of the fact that it may be cut and the layers combined in the US, it in no way qualifies as a “Made In The US” product when all is said and done.

Opinions?[/quote]

I think that the “made in USA” definitions are fairly clear with only a few slightly “fuzzy edges” so it would really be a matter of confirming with a good degree of confidence where all the foams inside their mattresses were sourced. It’s even possible that some of the foams are sourced in different countries.

Did you happen to look at your law label to see what it says?

Hi dzignr_tastz,

Thanks for the pictures … I appreciate it :slight_smile:

The production date on the law tag indicates that the mattress was manufactured on July 15th. 2014 so at least you know that the mattress was likely assembled in the US and wasn’t compressed during a shipment from China or in storage for a longer period of time which can affect foam durability.

The law tag also says “Made in USA” so that’s promising as well.

All that’s left (at least that I would want to know before buying any mattress) is to confirm that the foam materials are in fact manufactured in the USA or if they aren’t that they are CertiPur certified and more importantly to find out the quality/density of all the foam layers to be able to assess whether the mattress has any weak links in terms of durability and so you can make more meaningful comparisons to other mattresses.

OK… here’s one of my concerns with the whole thing (besides the obvious tear in the ‘cheesecloth’ surround, which was not of my doing although I did take the opportunity to take a peek at the layers as you can see). The tag also says it is a “Brentwood” mattress that was manufactured by Springfield Mattress, which is associated with SilverRest, both of which are associated with BRK Group, and SleepShop is a ‘company’ with no website but just an Amazon presence that sells multiple brands from the ‘group’ (pun intended), and ALL the company websites (or those have have them) are all administrated by the same company (and person in most cases), BRK .

So my question is… why exactly do you need 7 different corporate identities to produce and sell a single line of mattresses if there’s nothing ‘odd’ going on?

That aside, what are your personal opinions on the quality of the mattress (and I know you can only tell so much from pictures). The top layer obviously had a few blue gel beads throughout it, but it was still white (not blue) viscoelastic foam as a base, and was nowhere near similar (in my opinion) to the mattress toppers or gel foam samples I played with in a store or two, nor do I think it has the compression or comfort levels of the other samples (which could have been lower densities or just well broken-in). There is definitely a ‘memory’ characteristic to it, but considering the bed is excessively firm in both my and my partners opinions (which was my primary reason for going on this current journey before deciding how to handle my displeasure), especially below the top layer, I’m just curious to hear others, more educated opinions on the overall composition of the thing… you know, aside from the noticeably sloped sides as you go from bottom to top and torn surround which is too tight (despite being stretchable fabric) and compresses the corners slightly (this much worse on some customers’ final product).

I mean - I know it’s an “affordable” memory foam mattress, and I figured they would ‘cut corners’ (again… pun intended) somewhere, as the cliche “you get what you pay for” usually applies across the board, but at this point I’m undecided as to what is ‘acceptable’, what constitutes manufacturing defects, and how much of a fight I’m willing to put up for he price I paid.

Thanks for all the help!

Hi dzignr_tastz,

This in and of itself wouldn’t be a concern for me and there are many manufacturers that have multiple brands that are sold through different channels. It’s a fairly normal marketing practice that is designed to attract different target markets.

The only way to assess the quality and potential durability of a mattress relative to any particular person would be by knowing the specific type and quality of all the materials and components inside it (see this article). Without this information there is no way to make any meaningful comments about a mattress or make meaningful comparisons with other mattresses because you can’t “feel” or “see” the quality/durability of the materials. I personally wouldn’t buy a mattress where reliable information that a consumer would need to make an informed choice wasn’t available and I would consider it to be a “high risk” purchase with a much higher chance of buyers remorse.

For me I would treat “unknown quality” and “low quality” in the same way (high risk). IMO … there are too many reliable, knowledgeable, and experienced manufacturers and retailers that are completely transparent about the mattresses they make or sell and that sell good quality/value mattresses relative to their price range for a consumer to spend much time trying to “pull teeth” to find out information that should be easily available.

Hi dzignr_tastz, as far as multiple companies belonging to one another it is very common. From Zinus, parent company to Spa Sensations, Vivon, Night Therapy, BestPriceMattress etc to something people may be more familiar with like Unilever brand who heads up numerous large companies like Suave bath products, Axe brand bath products, Degree, Lipton, Ben & Jerry’s, Klondike… Unilever controls over 1000 huge name brands of everything from tea bags to snack chips, ice cream and health and beauty products. Not only do they target various markets, men vs women vs different age groups, etc, some of their brands also compete and it’s a win/win.

For that matter, Tempurpedic now owns Sealy and Serta/Simmons are owned together. So instead of 4 companies, you really have 2 major corporate ownerships. Also it’s interesting to know (if wikipedia is correct on this), that Serta was founded in 1931 by not one person but 13 mattress manufacturers, became controlled by National Bedding Corporation which in turn was purchased by two private equity groups: Ares Corporate Opportunities Fund and Teachers’ Private Capital (part of the Canadian Teacher’s Pension Plan). As just a normal part of the population where Serta (and other S brands) were a part of bedding brands as a household name, and not being privy to the industry, I would have had no clue Serta was so complicated. I just assumed it was a stand alone company.

Hi brass,

Not that it matters much but Simmons and Serta are now owned by Advent International (see here).

In addition to the TempurSealy International combination (which also owns Stearns & Foster) and Simmons and Serta being under common ownership the largest airbed manufacturer and 5th largest mattress manufacturer Select Comfort (aka Sleep Number) also bought Comfortaire the second largest airbed manufacturer.

There are other examples of multiple brand ownership in the top 15 or 20 mattress manufacturers as well such as Mattress Development Co being a Therapedic licensee and also owning Eastman House and Eclipse (see here) or the Kluft/Aireloom North American partnership with VI Spring.

Yeah… I could see that, given that there actually are “different channels” or “target markets”. In this particular scenario with SleepShop, however, it seems they are trying to simply create the impression of competition where, in reality, there actually is none, and they (directly or indirectly) control and manufacture every different brand sold in their Amazon store.

On that same subject of “marketing”, however… while some companies might be more ‘forthcoming’ with specifics of the materials than others, how does the consumer really know that’s what they’re getting in the end, or if the manufacturer is even being truthful in their specifications (unless it’s simply a big time manufacturer with a good reputation and some sort of regulation)? Someone that purchased this very same mattress said the company quoted the densities as “Gel: 4 lbs, Core: 5.4” (which are only 2 of the 5 layers, so again, and incomplete - and somewhat misleading - answer), but I won’t begin to proclaim to know what different densities of foams feel like. All I know is the one time I emailed them after feeling the initial (and still) firmness of it they replied with “Our 13 inch mattress is the softest feel we currently offer (apparently, across all their models) and is made to have a plush ‘sinking in’ feeling”, yet in my opinion, aside from the top 3 inches of memory foam compressing (which I can feel ‘molding’ to my body), it is extremely firm from there down, with very little give (which might be good for longevity, but not much for comfort). In fact, I had no idea a memory foam product of any sort could be this firm, which I guess was my primary misconception after randomly testing a VERY comfortable gel foam Serta in Big Lots one day while picking up a few things during a 20% off store-wide sale. Had they offered that one in a king-size (but didn’t… queen only, period), I would have bought it on the spot, but that is what gave me the itch and I guess I jumped in too quickly looking for something else in a semi-comparable price range. Lesson learned… :confused:

(My - lengthy, if you hadn’t guessed - Amazon review, under the same name, kind of explains how all this came to be if you have some - more - time to waste - LOL!)

I guess that part of the knowledge equation just comes from actually testing well-known mattresses of different materials in-store (not that I would feel great about wasting someone’s time to ‘edumacate’ me and then turn around and buy from someone else based on comparison)?

Totally understandable. However, since I apparently jumped the gun on this endeavor and didn’t put in the time, in advance, to thoroughly research what I was buying (shame on me), I don’t mind putting in a little after the fact to get to the bottom of what I actually received… and quite frankly, don’t mind ‘pulling a few teeth’ (not mine, mind you) in the process if deemed necessary to get the answers I’m looking for.

Anyway - thanks again, and sorry for taking up so much of your undoubtedly valuable weekend!

Hi dzignr_tastz,

It could be argued that you can’t (even with large manufacturers) and the same would hold true for any consumer purchase where you would need to tear it apart to really know what was inside it. You could also weigh every mattress that you purchased to see if the specs came out close to the weight but in practical terms you would be reliant on the reputation and integrity of the manufacturer. It would be a big risk for a reliable manufacturer to misrepresent foam densities because they can be calculated from the weight and volume of the material and it’s much easier to lose a good reputation than to develop it.

This is one of the reasons that I so often suggest that who you buy from and their knowledge, experience, transparency, and integrity can be one of the most important parts of a successful mattress purchase.

You can’t “feel” or see the quality of a material and the “suitability” or “comfort” of a mattress in terms of PPP is very different from assessing the quality/durability of a mattress because even very low quality materials can feel the same as higher quality materials in a showroom or when the mattress is new … they just don’t last as long. Suitability, durability, and the other parts of each person’s personal value equation are all important parts of the “value” of a mattress purchase (see post #13 here).

I read it when you first mentioned it … and like others that are probably reading it as well I’m still waiting for the “punch line” :slight_smile:

No problem at all … you are asking some good questions and I don’t stray far from the forum anyway … on weekends or weekdays.

Oh… I fully understand a single, parent corporation owning and/or manufacturing many different brands of products, some that even compete with each other (P&G would be another well-known one), but there is usually some sort of well-researched marketing reason behind those ventures, like targeting men vs. women (as you stated), or different economic groups. I can also understand one mattress company buying out another (and perhaps, eventually another, and another), well-established one and not just tanking the obviously valuable corporate identity, but I also didn’t see Tempurpedic trying to flood the market with bargain-basement manufactured memory foam mattresses under several different brands all in the same store right out of the gate, either. :wink:

23

Hi dsignr_tastz, the competition may not come from their own store if they’re promoting their own brands, but from others in a similar category also sold on amazon or elsewhere. They’d be competing against dreamfoam’s lineup of memory foam, night therapy, lucid etc. It sounds like whoever answered the question of densities didn’t understand the question or how to answer and gave what info they could, which would be the foam density for the memory foam and the thickness (not the density) of the core foam. This would be from people without proper education on the product or materials. Trying to determine the feel of different polyfoam densities would be hard to do. I’m sure they have a slightly different feel either in compression subtleties or weight - but for polyfoam, density doesn’t correlate to firmness. You could have low density foam (larger air pockets) that felt the same, softer or firmer than another piece of denser foam (more poly material, smaller air pockets).

I think in the end, while we spend 8hrs (give or take) a night on a mattress, it’s only one of many products we encounter day to day. No one wants to be hoodwinked by any manufacturer’s or products claims. But in the end, without being there every step of the way during the production process you (or anyone) just has to trust the company. Even if they go to the trouble to provide spec sheets, shipping labels and other ‘proof’, do we know that the proof actually applies to what we’re dealing with? I wouldn’t stress over it if the mattress is working well for you. Even confirming every small piece of evidence doesn’t guarantee a wonderful night’s sleep. As a matter of fact, from personal experience I think I lost more sleep ‘investigating’ things on my mattress hunt than I did from my wore out mattress :stuck_out_tongue:

Phoenix, thanks for the info. I don’t know all the ins and outs but like many things in the corporate world - finance and transitions, deals, etc it seems things are constantly changing. It doesn’t surprise me there have been even more shifts in the Simmons/Serta end of things. I think too part of the confusion is just not being that involved in the business. People in general take it for granted that if it’s got a label from XYZ corp, that’s who made it start to finish. I know it doesn’t usually occur to me when confronted with products on a store shelf that I’m probably debating between the same main brand lol.

Good points. I’d just like to add that it would be a big risk for ANY manufacturer (reliable or not) to misrepresent their product. :wink:

So in regards to densities, comfort level, and durability… aren’t higher densities more durable, but also more resilient, making them more firm, or is it possible to have a super soft, easily compressed, 5.4 lb. density, durable foam? It would seem there has to be some compromise somewhere, and while I’ve have done some reading about IFDs and the like, I am by no means an expert on it.

Well that top part was posted quickly in lieu of everything I found last night (before posting here), but I guess the ultimate “punch line” will mostly depend on what the final, combined results of my research are, and what the company has to say come the first of the week. Until then, I’ll stand by the fact that given what I now know, I wouldn’t have done business with them and wouldn’t recommend it to anyone else, either.

No problem at all … you are asking some good questions and I don’t stray far from the forum anyway … on weekends or weekdays.

Phoenix[/quote]Neither do I, obviously. :wink:

Hi dzignr_tastz,

With latex density is directly related to firmness (but only if you are comparing the same type and blend of latex).

With polyfoam and memory foam density is the most important factor in the durability of the material (see post #4 here and the posts it links to about the variables that can affect the durability and useful life of a mattress relative to a specific person) but any density of memory foam or polyfoam can be made in a wide range of firmness levels. Density does have more of a connection to the compression modulus of the foam which is also part of perceived firmness (see post #4 here) but it’s not directly related to comfort or firmness. There is also more about some (but not all) of the different foam specifications that can affect the feel or suitability of a mattress design in post #2 here. Resilience is a measure of the percentage rebound when you drop a steel ball on a layer of foam. Memory foam for example has almost no resilience regardless of its density because it’s a slow response material that “absorbs” energy (and turns it into heat) while latex stores energy (like an innerspring) and then bounces back and has a higher resilience than most other types of foam which is why it’s more “springy” or “bouncy”.

Phoenix

26

But why create a totally different identity to compete with DreamFoam, Lucid, etc., as they were already selling memory foam mattresses under the SilverRest name (and still are). I guess perhaps they could have just wanted a ‘memory foam only’ brand…

And yeah… didn’t know, or they were just spouting random numbers off the top of their head.

So if density doesn’t really relate to softness or firmness, than what does? I know IFD basically measures softness (deflection = resistance), but what determines how much resistance there is (as there’s plenty with mine - LOL)? I was under the assumption that since air compresses more than a tangible substance (especially when allowed to flow out of it), how many air pockets there are in the foam and their size (which sounds like your description of density) would have a lot to do with softness and overall compression? I mean, if there were no air pockets whatsoever, would it not be semi-rigid?

Thanks for the explanation. And while I know when we speak of “comfort”, like “beauty”, it is in the eye of the beholder, I guess I’m more focused on the term “sinking in feeling” (as I was informed), which I assume would definitely be, at least partially, related to density, as that would have more to do with the “compression modulus”. And on that same note, I believe I meant to use “resistance” (thus opposing that “sinking in feeling”) as opposed to “resilience”.

Hi dzignr_tastz,

Even IFD isn’t a reliable indicator as to how soft or firm a material will feel for a specific person because in most cases it only measures softness and firmness when a 4" (in the case of polyfoam) or 6" (in the case of latex) is compressed by 25% of its thickness (and even this varies in different areas around the world and isn’t always standardized) and different materials will also get firmer at different rates as you compress them more deeply (compression modulus). ILD is also not a reliable way to compare firmness between different types of materials (see post #6 here). There are also different “types” of softness that different people are more or less sensitive to (see post #15 here) not to mention that body weight, sleeping positions, and individual sensitivities will also affect the sensation of softness. The most reliable way to tell whether any individual mattress feels soft or firm for any specific person and “how” it feels soft or firm would be their personal experience.

So what do you think it would take to get some real answers here (not from you, but from the company)? It seems I have now found the option of just cutting through all the rigamarole and directly emailing the VP of Business Development (or ‘Deterioration’, whichever it may be potentially be based on my ultimate review) for BRK and see if he’s interested enough in my particular situation to either find out the answers to my questions or put me in touch with someone who can. After all, I don’t think an entry-level (if they have that many levels in the company) CS rep will be able to address everything I’ve discovered, addressed here, and would like to know…

Thoughts?

Hi dzignr_tastz,

It would certainly be worth a try to see what happens as long as it would be worth the time and effort for you and I for one would be interested in what they had to say and anything you were able to discover :slight_smile:

Phoenix[/quote]

Before I head off to sleep on it again, a quick update. I decided to just try a “only tell you half of what I actually know” approach with CS and here’s what I got on the specs…

Here is the apparent breakdown of the layers:

  1. 3" Gel Infused Memory Foam Layer 3.0lb Density and 16ILD
  2. 1" Extra Comfort Layer is made from High Resilience Foam with 2.0lb Density and 15ILD
  3. 2" Ventilated Layer is made from Perforated High Resilience Foam with 2.0lb Density and 30ILD
  4. 7" Base Layer is made from High Resilience Foam with 2.0lb Density and 30ILD

I also asked about the compression modulus but got no response on that. Not sure if it’s a measurable and/or publishable spec? I also may ask about the percentage of gel in that layer. Also, the foam was apparently manufactured in the city I work in (the irony), by HSM (Hickory Springs Manufacturing), who is, in fact, on the CertiPur list. I actually know a few people that work there, so I may try to see if I can confirm this.

Anyway - from what I now know, the densities don’t seem very high for a “25-year warranty”, and the person that gave them to me described it the mattress as “medium firm to medium soft, which could vary by comfort interpretation, weight, and/or temperature”.

Your analysis? LOL

32

Hi dzignr_tastz,

As you mentioned Hickory Springs is a well known North American manufacturer that is CertiPur certified so there would be no issues there if that is in fact where they are getting their foams.

Compression modulus isn’t a spec that any manufacturer is likely to provide and in many cases they may not even know it.

While the foam may be a high performance foam and have a higher resilience than conventional polyfoam … the minimum specs for HR polyfoam is 2.5 lb density or higher and a compression modulus of 2.4 or higher so 2.0 lb polyfoam is HD not HR although it may still be a higher performance foam.

If the specs you were given are correct then you could calculate the weight that the mattress “should be” for the different sizes.

queen size = 60" x 80". 3" of 3 lb memory foam should weigh 25.0 lbs and 10" of 2.0 lb polyfoam should weigh 55.6 lbs for a total foam weight (not including the cover) of 80.6 lbs. The listed weight on Amazon is 50 lbs which is 38% lower than it should be.

king size = 76" x 80". 3" of 3 lb memory foam should weigh 31.7 lbs and 10" of 2.0 lb polyfoam should weigh 70.4 lbs for a total foam weight of 102.1 lbs. The listed weight on Amazon is 65 lbs which is 36% lower than it should be.

cal king size = 72" x 84". 3" of 3 lb memory foam should weigh 31.5 lbs and 10" of 2.0 lb polyfoam should weigh 70 lbs for a total foam weight of 101.5 lbs. The listed weight on Amazon is 65 lbs which is 36% lower than it should be.

full XL size = 54" x 80". 3" of 3 lb memory foam should weigh 22.5 lbs ad 10" of 2.0 lb polyfoam should weigh 50 lbs for a total foam weight of 72.5 lbs. The listed weight on Amazon is 43 lbs is 41% lower than it should be.

In a mattress in this price range with foam that is sourced in North America it’s not likely that there would be 10" of 2 lb polyfoam in the mattress. While Amazon’s listed shipping weights may not be exact or correct and foam densities can also vary and also aren’t exact … either the shipping weight on Amazon is very wrong or the specs are incorrect. I would suspect that the specs are incorrect.

I would consider 3" of 3 lb density memory foam to be a weak link in a mattress and would normally be enough for me to exclude considering it as part of prudent “risk management”.

If the other layers were really 2.0 lb US made polyfoam then they would be good quality but I have my doubts that the specs are correct.

To make the numbers add up (assuming that the listed weights are correct which may also not be the case) and if the memory foam is really 3 lbs then the density of the polyfoam layers would need to be more than 1.0 lb/ft3 lower which would mean that it was less than 1 lb density which would be exceptionally low quality.
