I bought this mattress and after almost a month, it still did to inflate all the way. It is currently at 10-11in high. I tried calling the number provided in the description but since I bought it in store, I had to call the store directly. When I explained to the store the issue I was having with the mattress I was told I needed to bring it in. This is a King mattress and I live by myself, I cannot carry a 127 lb mattress into Sams Club. I was told "that was my problem and not Sam's Club." I am unable to return it or get a refund for a mattress that is defective. This was poor quality on a mattress sold as well as poor customer service by Sam's Club.

This is my favorite mattress! I have replaced all the mattresses in my house with this one. I have back and neck issues and sleeping on this mattress is a dream! I don’t wake up with a back ache!! It cradles your body without leaving indentations. It’s not too hot. It’s just perfect for myself and my husband.

Comfortable and sturdy

Not sure why other people have had size issues but this mattress DEF expanded after several hours to 12". We did lay it flat on the low profile box spring and didn't sleep on it for a day. And another person saying the cover couldn't be removed to be washed is wrong...there's clearly a zipper for removing the cover on the bottom of the mattress. It doesn't get easier to buy than this...box has handholds and wheels so you just pull it to your truck or SUV and load 'er in! Slept great on it and for the $, it can't be beat. Sure, I had a $2700 Temperpedic full foam in past....but it was warm and while I dont sink as deep in this Serta as I did in the Temper, I didn't notice while sleeping or waking without any aches. SO...money saved and value received.

Purchased in Club. Firm Base layer is about 6 in, top 6 in is 3 layers of foam. I am big guy 240 lbs and 6'1". Way too soft for my back, and had trouble rolling over, felt like I was sinking. I returned it for one with thicker firm base and thinner soft top layers-no back pain and i can roll over without a struggle. No problems with the return at Club.

I was very skeptical about this mattress. Have been looking at similar products i.e. Purple, Nectar, etc. Seems the closest competitor for this level of quality and type was still close to twice (at old price) the price but now at this price, this thing is a "no brainer" It is on the firmer side (even for my big fine body 6'1" and 225) it was a little firmer than expected. Bad thing? Not really. The support really seems to be helping. Also noticed that wife who used to snore loud enough that the walking dead would knock on the door to inquire what was wrong now seems to sleep nearly silently. A very welcome side effect. So overall is it in the same league as say Purple, Nectar and all the high priced stuff? I think so. Is it one helluva deal? You bet!

i have bought 4 of these mattresses, or at least i tried to. the first one i bought was a king and queen. after hearing amazing reviews i figured i’d give them a chance and after unboxing them and waiting the 48 hours they didn’t blow up all the way and they weren’t comfortable. after being sad about it a month later, a friend told me they got another and it was great. silly me, i decided to give it another shot and i got a full sized since i wouldn’t be sleeping on it regularly. this one actually did inflate but there was a tear on the side of it that i didn’t notice for about a week. i’ve heard so many great things about these mattresses so it was sad to have this happen. lastly, i got one more which was for a family friends birthday present because, against what i said, she wanted to try it out. and no surprise, it didn’t inflate. my fault for believing in the company but i wouldn’t recommend them. luckily, sams club refunded me for the mattresses and we just discarded them ourselves. i wouldn’t recommend these boxed mattresses.

We purchased this mattress at our local Sam’s Club 16 months ago. We got it to replace a 10 year old Serta mattress that had been great to us. We read through hundreds of reviews and decided to give it a go for the price point and overall positive rating. We both have horrible lower back pain since getting this mattress and it continues to get worse. There are indentations/slumps in the mattress on both sides where we sleep. I have resorted to sleeping at the top and foot of bed where there aren’t slumps but still wake up every single day with lower back pain. We wanted to love this mattress, but unfortunately we wasted our money and will be replacing it with something of better quality. We trusted the Serta brand but sadly won’t be purchasing another one of their mattresses after this.

Its like sleeping onm a cloud. I'm ovber 300 lbs too.

Its like sleeping on a marshmellow
