Good product
That it takes a while to get here and the tracking is not always accurate but the mattress seemed to be in good shape.

Most uncomfortable mattress
If I could give this mattress zero stars I would. This is the most uncomfortable mattress my husband and I have ever slept on. It started sagging as soon as we started sleeping on it. All night long I have leg, thigh, and hip pain while I am trying to sleep. My husband has a very strenuous job and has not been able to get a good nights sleep since we started sleeping on this mattress. Unfortunately when we bought the mattress we were in the process of moving 4 hours away and had it in storage so we missed the 30 day return window. Don’t make the same mistake we made, find another mattress!

Extra comfortable
The mattrerss is very big.I got a Queen size and needed help to get it in the house, but when I got to sleep on it-it was like sleeping on a cloud.I slept on one at my cousins house when I visited and just had to have one.

Amazing comfortable mattress!
We wanted a mattress with coils and not foam. The quality of this mattress is excellent and the cost less than our local furniture store. It was delivered when promised and they will offer to haul away old mattress. Great buy!

Comfy and back supportive, sides breakdown easily
First, great quality and comfy mattress. Replaced our old one that was 15 years old. I’m a side and stomach sleeper. My wife is a side and back sleeper. We’re getting better sleep for sure. My only complaint is the sides/edge support breaksdown very quickly and easily. I’m no skinny mini I’ll admit, but after a couple weeks i go to sit down on it and I’m already feeling the pushback from the side frame of our bed. We have a slat base bed set, no box spring. Figured for the price the sturdy construction in the middle of the mattresa would’ve extended to the sides/edges. I was wrong. I’d recommend to someone, but make them aware of where the quality stopped.

Wonderful bed
It was a little more expensive on Amazon but I went ahead with it based on how easy it was to coordinate delivery and because in the end Amazon never lets me down. Lovely mattress that I’m using for my guest room. I’m still convinced Serta makes the best mattresses
