How can I durably replicate that showroom pillow topper feel?

Hi jezz.

Welcome to our Mattress Forum! :slight_smile:

Thank you for your appreciation.
Quite a bit of information and challenging questions – perfect for TMU!

I am sorry to hear that your 2014 Simmons mattress does not serve you any longer and although I don’t know if this was an “entry” level product you’ll generally get only 4-5 years from brands that use lower quality materials in their componentry. Many manufacturers make a wide range of mattresses that can vary from lower quality and less durable materials to higher quality and more durable materials in a wide range of prices.

The major brands such as Sealy/Stearns & Foster, Simmons, and Serta all tend to use lower quality and less durable materials in their mattresses than most of their smaller competitors that will tend to soften or break down prematurely relative to the price you pay which is why I would generally suggest avoiding all of them completely (along with the major retailers that focus on them as well) regardless of how they may feel in a showroom along with any mattress where you aren’t able to find out the type and quality/durability of the materials inside it (see the guidelines here. along with post #3 here. and post #12 here. and post #404 here.).

PranaSleep is basically a latex mattress with a polyfoam quilt panel that uses proprietary foams and has better quality and materials than your previous Simmons mattress. The 2.5 lb quilt-able polyfoam is very high density (unique to quilt layers) The high density foam in the comfort layers is very good quality (giving overtime only a minimal loss of height i.e. body impressions), has a non-woven material “wrap” around the foam layers as well as exceptional initial comfort with no weak links.

As mentioned before the 2.5 lb poly would be a good quality and durable material and there aren’t generally any materials for a cause of concern quality-wise per what is listed by Jordan’s. If ever in doubt
You always want to make sure that you find out the information listed here so you can compare the quality of the materials and components to the durability guidelines here to make sure there are no lower quality materials or weak links in a mattress that would be a cause for concern relative to the durability and useful life of a mattress before making any purchase.

Resiliency isn’t durability, but an indicator of surface “springiness” or elasticity. More resilient is more buoyant feeling, The material listed are in actuality better quality and you can read about materials and components that are all high quality materials that are very unlikely to reduce the durability or useful life of a mattress in the the durability guidelines mentioned abovet

Having a quiet room can help someone relax and be less self-conscious trying out a product, but the comfort of the mattress is the same regardless of where it is placed in a showroom.

It is unlikely that you will be finding any off the shelf products that match exactly the feel of Parana. From your description and excitement it appears that you are considering not just a DIY latex mattress design, but one in which you design/engineer it yourself. Although this can be a lot of fun it entails a lot of trial and error as you would need to gather a great deal of experience in the process. If you are attracted to the idea of designing and building your own DIY mattress out of separate components that are purchased from one or several different sources then the first place I would start is by reading option 3 in post #15 here and the posts it links to (and option #1 and #2 as well) so that you have more realistic expectations and that you are comfortable with the learning curve, uncertainty, trial and error, or in some cases the higher costs that may be involved in the DIY process. It is also very doubtful that you will be able to exactly replicate the feel of Prana.

I would strongly suggest avoiding the temptation of trying to design your own mattress based on specs (either yours or a mattress) and instead work closely with the retailers and manufacturers that are of interest to you and use careful testing and feedback from your own body along with the expertise each of them has about their own mattresses to help you make your best choices. Your body doesn’t understand specs … only what I call PPP (Pressure relief, Posture and alignment, and Personal preferences)
You would be better off talking with a knowledgeable retailer or manufacturer and while you are clearly free to pursue this, you may want to check with some of TMU’s Trusted Members who are very experienced in latex, such as:
For Latex or All Latex sytems
For Innerspring Hybrids
For Poly Memory Foam combos

The Diamond Quilted Mattress Cover you cite is a mattress encasement using 2" of polyester fiber and 1" of latex quilted.
(very different than 1-2" of 2.5 lb polyfoam that you seem to like)
A 2" or 3" wool topper will also produce a comfortable, but different feel than your experience with PranaSleep. There is more information about choosing a topper in post #2 here and the topper guidelines it links to, which along with a conversation with a reliable and knowledgeable supplier (that can provide you with good information about how their toppers compare to each other or to other toppers they are familiar with that are available on the market), can help you use your sleeping experience as a reference point and guideline to help you choose the type, thickness, and firmness for a topper that has the least possible risk and the best chance for success.

While it can certainly be a rewarding project … the best approach to a DIY mattress is a “spirit of adventure” where what you learn and the satisfaction that comes from the process itself is more important than any cost savings you may realize (which may or may not happen).

I hope this gives you enough information to help you narrow down your options.
