Fixed the pocket coils on a year old mattress; is this common?

Just 10 months after we bought it, our Beautyrest PressureSmart 12.25" Plush Mattress developed a sinkhole deeper than my disappointment with the whimsically named chain store we got it from: 4 whole inches.

Now this thing is advertised as having a total of all of 2" of various comfort layers, half of which is quilted to the top cover, and even though I grew up using centimeters, I have it on good authority that 4" is more than 2", so I suppose I could have seen it coming that there was damage to the actual springs. But, encouraged by statements on the internet to the effect that polly-put-the-kettle-on foams wear out fast but springs are usually fine, I figured I’d open the thing up, just in case the springs were salvageable for use with a new topper of some sort. No such luck.

This thing is clearly not designed for long term use by two adults. It’s definitely not designed to support a human being of 330 pounds. I want to get a new mattress. But for now, I and my partner have to sleep on this mattress-shaped object, and the hole was not exactly conducive to that. Not only did it hurt the back of whoever had the misfortune of lying on top of it, but it also caused the other person to gradually slide down toward and partially on top of the hole dweller, which sounds more hilarious than it is when it wakes you up at 4am. Thus I proceeded to consider how our bed might best be mended.

As you can see if you look closely, the springs are enclosed in tubes of non-woven, very flimsy fabric (polypropylene?), with lines of stitching between each coil, and some sort of reinforcing tape roughly in the middle. This produces lines of loosely coupled coils that are arranged down the length of the bed, and every coil is then attached to its width-wise neighbors with what looks suspiciously like 2 globs of hot glue. (To be fair, hot melt adhesives are common in textile manufacturing, and there’s “fusible” interfacing aplenty in most shirts and suit jackets. But this stuff really looks like hot glue. Or maybe it’s just the actual fabric melted together. Not sure.) In the area of the 4 inch sinkhole, the upper glue joint between each pair of adjacent coils had either failed itself or ripped a hole in the “fabric” around it.

Trying to reattach the fabric seemed like a fool’s errand on account of its overwhelming flimsiness, so instead I opted to attach the tops of the actual coils to each other. I grabbed a spool of the strongest thread I could find (some sort of upholstery grade polyester) and ran blanket stitches down the rows like so, and for good measure covered the whole thing up with a scrap of strong, lightweight polyester fabric that I don’t especially like anyway.

With all the “PressureSmart™ Gel Memory”, “AirFeel™” and “Plush Comfort” foam back in place, the side that had the hole now feels… about the same as the other side, which still isn’t great, but should do until we can get something better. I’m actually surprised the repair worked this well. I don’t think I’ll bother re-attaching the top for now; we keep the whole thing inside of some sort of zippered pouch anyway.

And now: some questions.

  1. How common is this failure mode?
  2. How would you go about repairing this, if at all?
  3. Do you think it makes sense to incorporate the mended spring layer into a DIY springs-and-latex mattress, or should I just buy all new?

Hey coba,

Welcome to The Mattress Underground :slight_smile: ! Thanks for your question.

Wow; 4 inches is a “whole” lot of sink for a new mattress, coba. Thanks for including the well-summarized and well photographed essay of your disappointing mattress shopping experience. Your frustration with this failed product rings loud and clear, and I wish that I had more encouraging advice for you.

I did some online investigating of the Beautyrest Pressure Smart 12.25" Plush model and was unable to find any product specs to support the mattress’s durability potential vs. a high BMI user’s needs (not a surprise as they do not generally publish what their proprietary ingredients’ details are). Still, the mattress’s coil unit should have lasted longer than the time period you describe. You don’t say where you purchased yours, but Mattress Firm’s site offers this model and according to Beautyrest’s 10 year limited warranty, normal body impressions are considered to be 1 1/2" or less. Have you reached out to the retailer regarding the manufacturer’s warranty? There is no recourse now as you have opened the mattress and created a temporary work around, but it may be worth a shot to report your experience.

Answers for you:

[indent]1. Unfortunately, we don’t have a data base for reports of various types of product issues. That is beyond the scope of services we offer; however, you can use our site search feature to explore the topic and see if others have reported problems with your mattress model.

2-3. Your makeshift repair is interesting and creative. Not sure how long it will last, but it sounds as though it has made a difference for the better. The other thing you could try is adding a size appropriate piece of similar comfort materials from a DIY resource. Comfort problems are more readily remedied; however, once the mattress has a support failure, it is generally time to move on to something new.[/indent]

Let us know how things go and hope you find more restful sleep soon :wink: .

I have had the same experience with Beautyrest PressureSmart 2.0 Firm 11" mattress. Issue started within 6 months of having it. Flipped it around and had the same thing on the other end. Mostly a side sleeper and a depression formed under my shoulder. I could feel that the coils seemed to be stuck under the neighboring coils. Was considering taking it apart which is what brought me here.
