Our bed is sagging: Can we fix it?

August 27, 2012 6:54 PM

My now-wife (then-girlfriend) purchased a new queen-sized mattress from Macy's about 3 years ago. We've recently noticed that the bed is sagging on both sides where we sleep, and the middle and sides are firmer and the way they were when she purchased it. It has a split box spring so that it could fit up her narrow staircase in her former apartment. We no longer have that restriction. So, is this the fault of the split box spring (and should we replace it with a normal one), or is it simply a problem with the mattress? What can we do to fix it, if anything?

Of course, we can rotate the mattress and have done that with no effect. We can't flip it because it has a pillow top.

Best answer: Sounds like a problem with the mattress. What kind of warranty did it come with? If it's still under warranty, call them up and see what they'll do. [My aunt had this problem and used the credit they gave her to buy a new, better mattress.]

Is it a pillow-top style mattress? (Aha! On re-read I see it is.) Ours is, and it does the same thing. It's the filler making a nest around us or something. To be expected if it's a pillow-top. Ours is double-sided so we do flip it.

This has happened to everyone I know who has bought a pillow top, including me. Perhaps not coincidentally, everyone I know with a pillow top mattress says they will never buy one again. Including me.

We had this happen on a fairly high end (not Hästens, but not Simmons either) mattress, and their official line on the warranty was that the impression had to be ridiculously deep (I forget the measurement, but it was way more than we'd consider acceptable) before it would be considered a defect. I've read similar things from other people about other brands. So not only is it "expected" on pillow-tops, but the warranty is likely to be of little use. In our case, the store we bought it from actually replaced it for us to keep us happy, even though the manufacturer wouldn't. The replacement developed the same problems shortly thereafter, and we just got rid of it and replaced it with a foam mattress. It was an expensive lesson, but that's life. We've had the foam mattress for several years and haven't had any problems.

All that said, it doesn't hurt to ask about the warranty, and maybe raise hell with the store if the manufacturer won't help. The worst they can do is refuse to do anything. Even if it's an inherent problem in the product, if you get a replacement it delays needing to buy a new mattress for another year or two.

the way to prevent this is to frequent flip and rotate the mattress to spread out the loading and 'push' the pillow top material back in place. But yea, they all do this.

There are flippable pillow tops out there, if you don't have one already. It's not quite as squishy as a regular pillow top, but you can rotate and flip it, and it's way better than a regular pillow-top.

Best answer: On our bed it's just the fill in the pillowtop that has the depressions so I just bash the fill around when I make the bed the same way I fluff the pillows. It's not the mattress itself so it doesn't affect the comfort level of the bed. I don't see it as a problem.

Can you add a memory foam topper? I just bought a good one from Costco, ~120 for a queen size, and it's helped a lot. When it goes bad in a couple of years or so, just toss it and get a new one. I read somewhere that Brad Pitt recommends a relatively inexpensive but firm mattress (no pillowtop) with a memory foam topper, so it must be a good idea.

OK, here it is, straight from Brad's typewriter to your eyes...I only included the pertinent bit but you can find the entire article her http://www.esquire.com/features/ESQ1006ESQ1006_164R_2

THE PERFECT MATTRESS
Don't spend a lot of money on a big, giant mattress with double padding on both sides and all that. Just go out and buy a normal firm mattress. Then go buy the three-inch Tempur-Pedic pad, the memory foam, and put it on top. I'm telling you, take my tip. It's the perfect pressure. I take full credit for the discovery. You will sleep in bliss forevermore . . . unless you've got a six-week-old.

My husband and I solve this problem by switching sides every six months or so. I'm going to try the "massage the bed" approach to munging around the fill.

Instead of a pillow top, get a separate featherbed, which can be put on top of any mattress, and is easily fluffed every time you change your sheets.

I'm not sure if the rules are different for pillow tops, but we've had mattresses replaced under the warranty. I'm pretty sure the depressions have to be at least 1 1/2 inches deep. It would be worth checking with the mattress manufacturer to see what their warranty requirements are, and if it sounds like you qualify have someone come to take a look at it. We didn't have to replace it with the exact same mattress, so you could get a non-pillow top and use a topper pad, as has been suggested.

Here's a potential fix: Buy a featherbed or 3-inch memory foam topper. Flip the mattress onto the wrong side. Top with whatever topper you picked. Maybe this way you can flip the mattress periodically despite having a one-sided pillow-top, and the indentations will level out.

Response by poster: My wife was sure it was the fault of the split box spring, but we now have some other places to investigate. Thanks everyone.

How did this turn out? I'm considering buying a (non-pillowtop!) mattress from Macy's and I'm curious how good they are about replacement for sagging.
