We love this bed, it came compressed in the smallest box but man did it bounce back after it opened. It's our son's first "big boy bed" and we find someone sleeps in it each night with him because it's more comfortable than their bed. We purchased a full size mattress. We will be replacing our king mattress with this one the next sale.

After 24 hours the mattress hasn't expanded enough to fit correctly into my queen platform bed frame. The length fits correctly, but the width is a little narrow, leaving 1-1/12' of platform slats showing on the side of bed. This will probably not be visible once bedding is on, however when bed is in use, it will be. The box was pretty beat up upon arrival, tears in a few locations. Not sure if this has a anything to do with why it may not have expanded properly. I will give it another 24 hours. For now getting average rating.

Bought one 2 months ago, I was afraid not to find it again. I got lucky, now I'm ordering another one, for second twin bed in guest room. It is unbelievable comfortable. I can highly recommend this 12" night therapy top box mattress. Best purchase in its class. Cool delivery in the small box.

I bought this for my teenage son and it has just been amazing. With his old mattress he would have the hardest time sleeping through the night, but with this one he has no troubles. I am 6' and 220 lbs, it is firm but yet still comfortable when I lay on it. But seriously I think the coolest part of the mattress was opening it up. It came in a box that was about 2' x 2' x 4' rolled up and vacuum sealed. We brought all four of our kids into the room when we opened it. I started with a small hole and you could just hear the air being sucked into the packaging and the small 4" mattress started to expand. The whole family thought it was amazing to watch and everyone wanted to test it out. It did take a couple of days to fully decompress, but really I would say it was 98% there almost immediately. I went to a couple of mattress stores and with the size and ratings of this mattress the best they could offer was a 10" and they were still like $20 more. One thing I didn't know and I'm still not 100% sure, but I received an email from Samsclub.com on the quality of service and it seems you can have this shipped to the local store if you don't want to pay shipping. Shipping was $40 and it may be a deal breaker for some, but this bed is worth the extra cost of you choose to ship to your house.

I bought this mattress to go with the lightheaded bed that I also purchased from Sams for my 3 year old granddaughter. I took a nap with her a few times and the mattress is very comfortable. It was thick enough that i did not have to purchase a box spring.

Ordered this mattress from the Sam's Club website. Was skeptical ordering it online but other reviews were good so I gave it a shot. I'm glad I did. Ordered on 2/2 arrived on 2/9. Everything else was just like the instructions said. The mattress was vacuum packed and looked much smaller than the full size that I ordered. But once I removed the plastic casing, the mattress expanded to it's right size. Pretty cool to watch! We followed the instructions and did not use it for 48 hours so it would expand. I was happy that it did reach it's advertised height of 12 inches. This mattress was purchased for a guest bedroom so it will not be used daily, but it's been used twice already. My guests said it was very comfortable. I would buy this again if I had to.

First of all, I have never ordered a mattress in the mail before, watching it spring back to life is pretty awesome. The mattress is fairly firm, but it has a little cushion on top. I got the mattress for my son's bed, so I have never slept on it, but I lay on it to read him stories, and it is very comfortable! The mattress is also extremely quiet. You can't hear a single spring, which I like. We did have issues, but not with the mattress it's self. I didn't consider that the bed would be too thick for a day bed, but it is. We had to modify the bed to make the mattress fit. It was about 5" too thick. I am very happy with this mattress.

Purchased this to replace a cabin mattress. Little did we know it's identical in comfort as our more expensive mattress we recently purchased for our home. My husband is a side sleeper and I'm a stomach sleeper. We both sleep well and wake refreshed. We find our grown teenagers napping in it all the time...lol. We put it atop of our existing queen bedspring but are taking the advice and having plywood cut to place between the spring & mattress. Great value, great price.

This mattress was delivered quickly, and it was surprisingly easy to unpack / set up. It came in a box and expanded when it was taken out of all its packaging. I thought that was going to make it not as good, but this mattress is sturdy and very comfortable.

I cannot sit on the side of this mattress. it offers no support along the edge of the mattress and you slide off the mattress. The entire mattress has no edge support. If you roll to the edge of the bed while sleeping it does the same thing. I asked my daughter to sit on my bed and she said the same thing. Don't waste your money on this mattress
