Sagging Sealy Mattress Problem and Resolution
I bought a $1000 Sealy Posturepedic California king
size mattresses from Sears in February 2009 (plus the Sealy foundation
box springs). The first was a "Spring
Blossom" pillowtop, and immediately after we received it, my wife
and I would each sink
into holes on our sides of the bed. This caused us to wake up with a
backache in the morning, so clearly this was not good as we were
concerned it would cause us permanent back damage.
We returned that one (yes it was a hassle) and purchased
the firmer "Cason Bay" model, thinking it would not have that issue. It
was firmer, but we still sank into holes. Neither of us are very heavy.
I'm around 175 lbs, my wife is much lighter. Neither of these mattresses
displayed this issue when we tested them at the Sears store. We had been
putting up with it and were are losing sleep and waking up achy. The
middle seemed firmer for some reason, but we could not both sleep there
at the same time.
I spoke to Sears customer care repeatedly over the phone
and they told me there was nothing they can do.
The Sealy website states clearly that all issues are to
be dealt with by the retailer (Sears).
||I posted a note on
www.measuredup.com noting my displeasure and was then contacted via
email by Andrea from the "Sears Cares escalation team".
"First and foremost I would like to apologize for your mattress sinking
in the middle. I know how it is first hand to roll into the center (talk
about discomfort). Please see the attachment as it gives you step by
step institutions of how to take pictures of the mattress. You may send
the pictures back via email. The manufacture tag has to be attached and
no stains should be found in order to consider a replacement. Thank you
for your time and have a wonderful weekend!"
I took all the pictures
and met all the criteria but after 44 emails including a followup with
an Sears "executive case manager" I was told I did not meet the
|After that debacle I decided that would boycott Sears and
it's owner, K-Mart (Sears Holdings). I suggest that everyone else do the
same, as they have horrible customer service.
Here are the pictures
showing how much the mattress sags without any weight on it. With weight
on it it sagged at least 4" in the butt area.
We suffered with the Sealy Posturepedic mattress for 3 years. I read
many stories on the consumer report sites about other people with this
same problem. Apparently this is a common issue for Sealy, Serta, and
Fast forward to March 2012. I Finally had enough!
||I decided to cut the mattress open, find out what
was sagging and replace it.
How to fix a mattress:
Here's the whole mattress with box springs "before".
I cut the bottom of the mattress cover about an inch in from the
edge, My wife convinced me it would be easier to sew back together than
if I had cut through the quilted top.
There were a bunch of staples on the sides, but they were easy to
|Here's the mattress with the quilted cover peeled back.
The butt area has solid foam and everywhere else is sculptured.
Apparently the solid part doesn't do anything to prevent sagging.
||There were three layers of cheesy foam on top of the
springs. The top sculptured layer, a 1" layer, and a 1/2 layer. They all
seemed to be about the same density.
|The bottom layer had stains on the bottom, which I
initially thought was dirt, but now I think it's mold from body
moisture. The moisture was trapped by the non-porous plastic layer next
to the springs and was on both sides of the mattress where we sleep.
||Also there was this nice scrap of something by the mold.
|Here's the non-porous layer peeled back with the springs
exposed. Sides and bottom of the mattress are dense plastic foam.
I never did find anything that would make the center less saggy.
I thought maybe the springs are stronger there or the split foundation mattresses
gave more support there.
||We went down to a local mattress manufacturer and bought two 1" layers of
cotton batting, and replaced the moldy 1" and the not moldy 1/2" layers
They also had several varieties of foam, but they all felt
about the same density that we already had.
|We then stretched the mattress cover back over the
mattress. Initial testing showed the mattress to be firmer, but it no
longer feels saggy. Looks fine too. I think carpet tape will do a good
job of re-sealing the cuts on the bottom of the mattress, but I have not
taped it yet. Time for some
Sleep test: Initially it seemed that the issue was resolved
but after time the sagging was still present.
After more testing I determined that neither the box springs nor the
mattress springing were sagging. All of the sagging was due to the
remaining cheap sculptured foam layer.
We ended up cutting sections of the old 1" foam layer that were not
moldy and that were about 2ft x 3ft and placing them in the saggy
sections on each side of the bed between the cotton batting and the
sculptured foam section. This feels much better and the sagging is not
Now that we have sliced and diced our Sears Sealy Posturepedic mattress,
I can sleep on it without feeling like I am laying in a hole, and no
longer wake up with a morning backup.

I have had a sagging bed issue with my Sears Sealy Posturepedic
mattress purchased in 2009. This seems to be an epidemic issue. At that
time, Sears replaced one mattress but the second had the same problem
and Sears and Sealy were not willing to do anything else. I eventually
ended up dissecting the mattress and determined the issue was in the
cheap and mold prone (yes the foam was moldy!) foam that they were
using. I replaced the 1/2" layer of cheap foam and the 1" layer of cheap
foam with two 1" layers of cotton batting from a local mattress factory.
I then cut a 2ft x 3 ft piece of the 1" foam and placed it in the saggy
area between the remaining cheap saggy sculptured layer of foam and the
cotton batting. This seems to have fixed the issue and I can now sleep
without laying in a hole and no longer wake up with a back-ache. I have
a web page detailing this process. My conclusion is that Sealy (and
other manufacturers) are using sub-par foam and that they should replace
all the mattresses that they used this foam in.
