Best mattress ever!!!!!

I have now had the mattress for 3 mo. and I am sill as happy with it as I was the day it got here. The center support is great! I have never had a mattress that was so comfy. It is well worth the price. I have always had issues with mattresses sagging in the center and causing back problems, not with this one. I have tried sleep# mattresses too and this is sooooo much better. I like to gel foam also because it is cooler in summer and I don't have A/C. The only problem I could find with this mattress is it is very thick so you must buy deep pocket sheets.

6 months in and we are disappointed

Side sleepers beware! We've had this bed for only 6 months but it has developed low spots where we sleep and a high ridge in the middle. I sleep on the left side and sleep on my left side. Apparently, turning from my back to my left side causes the sheets, pad and actual mattress to drift toward the center of the bed. The hybrid foam section then bunches up in the middle. My wife sleeps on the right side of the bed and turns to her right, which does the same thing on her side. So now the center of the hybrid pad is about 2-3 inches higher than the rest. If you ever find the sheets under you are bunched up because of the way you turn in bed DO NOT BUY this bed. Next time, I will just get a regular pillow top inner spring mattress since springs don't migrate like this foam appears to.

Saggy Crappy RipOff


I bought this mattress from Sears at Ridglea in king size almost 3 years ago. WORST MATTRESS Ever! It is supposed to help keep you cooler with some little jell beads - hot as any other foam mattress. It is supposed to be firm. After less than 3 years it has a visible 1" sag!.
Because I am trashing the mattress I went ahead and cut it up to see what is usable. It has about a 3/4 inch layer of foam with holes and purple useless beads, then a 2" foam - standard "memory" type. Then a layer of black canvas over the "coils" - individually wrapped, held in place by hard foam - all glued together.
The coils are wrapped to try and keep shape, but because they only have 6 wraps and the wire is weaker/smaller gauge than a standard coat hanger, they give out quickly. You can actual feel them poke through the less than 3" of foam, and side sag in them causes the visible dips.
I have a series of photos I took of the disassembly process. I will NEVER buy this bed or brand (Sealy) again!!!

Upgrade for Us!


My dad is moving and he brought his bed to my guest room so he could have somewhere comfortable to stay when he visits. It is a PosturePedic with Eurotopper. We slept in it, imagining a staycation in our own house. Well, we want to switch rooms now! We both slept like angels. The bed offered better support than our current, tired mattress. I will definitely buy again when we replace our actual bedroom mattress. 

This review is part of an Influenster contest, but the opinions and good night sleep were all my own.

Love it so far!


We bought 2 sets of these mattresses and 2 sets of adjustable bases to go with them. The mattresses are nice and comfortable. I've had back problems for years and had been looking for something that would help me sleep more comfortably. Around 6 months we turned them (from head to toe) to switch it up so we don't get lumps in the mattresses because my husband and I are side sleepers. Glad we found these!

Dealt Posturpedic


I’ve had mine for 3 years now and it’s still going strong. I’m just now considering getting a new mattress, and that’s just because of the crazy sales going on right now.

Love this mattress!


Firm in all the right places but contours and cradles your body like a cloud! This mattress is great if you like support without having to sacrifice comfort. I highly recommend this mattress!
