Bought this for our 17 year old.  Didn't want to spend too much since 1. he's enlisted and wont be here much longer, 2. he still sweats when he sleeps and his other mattress had an "aroma" to it after 2 years so I wanted to be able to throw it out without a $1,000.00 guilt price tag and 3. stairs to his room made this a great fit for us.  He enjoys it very much, says he loves the way he sinks in to his bed at night.  Will definately buy again, at some point.

Perfect for what we needed!

I wake up in almost the same posture as when I fall asleep.  The comforter isn't all twisted up as it used to be on the previous spring mattress which to me indicates almost no movements during sleep.  I'm 70 and noticed fewer aches and pains upon arising.

Almost No Tossing or Turning or Aches and Pains

My $600 mattress I previously had left me in pain every morning. I moved that one to my sons room & put this new one (less than $300!) in my room. No more body pain!

Sometimes I sleep in my sons room w him & the old mattress doesn't bother me as long as I don't sleep in it every day. 

My son changes beds too. LoL he sleeps in his room & the 2 beds in the guest bedroom. I think the change in mattress helps.

No more body aches!

I was a bit concerned. After 24 hrs, the mattress hadn't decompressed much. I thought it may have been due to extended shipping time caused by the recent snow and ice.After 48 hrs, one half of the mattress was almost fully decompressed, but the other end wasn't. I started looking for return policy and came across some info that helped. I thought the mattress couldn't have any weight on it until fully decompressed. After reading that steeping, steeping,  or rolling around on the mattress helped, I tried that with some success. After 72 hrs, still had a ways to go in some parts of the mattress. I put it on the bed and began sleeping on it. It has completely decompressed and is very comfortable.

Disappointed at first, but very satisfied now.

My fiance and I researched a lot of beds before buying. He is a 245lb bodybuilder, so he is heavy on a bed. I am over 100 lbs lighter, but this bed fits both of our needs! We are both comfortable throughout the night. I don't feel him move in the bed at all and vice versa. Back aches from a miserable previous mattress are gone. The dogs love it too. Another worry we had was that memory foam mattresses were supposedly hot, not this one! Unpacking was easy, and fun. We didn't experience any smell. Sat out for 36 hours before we put sheets on and slept on it. Great feature I didn't even know about before ordering is the removable cover on the mattress. Fantastic mattress and you really can't beat the price (believe me I looked).

Comfortable for everyone

Bought it for my 80 year old mom who has chronic back pain. She says she wakes up with no pain at all now.

She loves it.

So far it’s great ! We purchased it because I hurt my back and could feel every spring in my pillow top Sealy mattress .

Comfy and firm

This mattress only raised up 6" not 8" as listed on the title.   Its comfortable but not as thick as i wanted.

Disappointed

Mattress only expanded to 6-1/2 inches, some spots as low as 6 inches.  The instructions said it could take up to 72 hours to fully expand so I let it sit on my living room floor for 6 full days to ensure it had enough time to fully expand but it never did.  Don't waste your money.

Waste of Money

The mattress arrived in a timely manner. However it never filled out after removing all packaging materials the center of the mattress never inflated fully and was crimped even after a full week of being opened.
