Went to the actual Sam's store and bought 2 twin size mattresses for the kids room. I did sleep on it for 3 nights in a row until our king mattress arrived and I'd have to say it was comfy and supportive and not too firm. Also was 7 months pregnant at the time and didn't wake up with sore bones or aches!

We bought this mattress for our daughter and brought it home. Opened it up and both sides of the mattress were curled up. We left it be all weekend over 48 hours and it never got to the 10” thickness and the sides are still curled up like a taco. We returned it got another one and it ended up the same way. It's the way they package it in the new smaller boxes. I hope they rethink this new packaging and go back to the way they used to package them. We ended up just buying the normal traditional twin bed for her. She is happy and is sleeping great!

I LOVE my Serta Stay mattress! It seems firm once you get in it but but it forms to your body. I couldn't sleep in my other bed any more it hurt my back and hips and tossed and turned all the time and wasn't resting at all. Now I wake up feeling fresh and don't HURT. I recommend this mattress to anyone. You will LOVE it like I do!

There is absolutely nothing about this product that my wife and I don't like. Its a very simple set up and we were sleeping on it in minuets. We have only had a memory top, so finally getting a gel memory mattress was well worth the wait. We both agree that we sleep more through the night than on any other mattress we have owned. Love it, love it thank you Serta!!!

Good overall

I bought 2 of these mattress 4 weeks ago. the annoying part is, even after waited for 4 weeks after opening, its not fully pop up as mentation of 11 inch. corners of the mattress are not completely flat. If i talk about the comfort, I bought this for my back issue but it is too extra firm for me and increasing my back pain instead of reducing it.

Comfy

I love the thickness, design, and comfort of this mattress. I've never had a foam mattress and because my husband is 6'2 and over 270 lbs... I hesitated him liking a bed without springs. He was wowed by the comfort of this mattress. We've had it for 4 nights and it honestly has been the best night sleep we've both had in a very long time. We've retired our old Serta and love our new one. I highly recommend this mattress. Happy that I was able to place it right on top of my existing box springs of our previous mattress.

I bought a Serra mattress for the first time one year ago. Within six months it was sinking in the middle. After a little over a year it has shrunk so much in the middle that I can barely get out of it. This is a terrible item and I'll never buy Serra again.

I bought four of these and three were wonderful. The fourth would never fill out. I have bought two more to replace that and all of them are curled and won't unfold. So disappointing when you buy it and drive it 3 hours only to find out for the third time that it is no good!
