First it felt weird, compared with the previous one, no spring effect and kind of hard. Then we realized it adopted our shape. Bottom line the sleeping quality have improved a lot.

For pure sleeping purposes I'd give it a 5 star. My one complaint is that the edges are very soft so I find it hard to sit on the edge of the bed and get dressed, put my shoes on etc..

It never expanded completely. It's about 9" thick after a week. It is very firm, probably because the foam never expanded. My daughter still sleeps on it, but it's kind of a disappointing product and a return of a mattress is quite difficult.

Contacted Sam's Club and they are sending a replacement but the initial mattress I received, has not opened or fluffed up as expected. Took it out of package same day received and even after a week, it has not expanded correctly or completely.

My wife now sleeps without back pain. Mattress has doe what we wanted it to. I would recommend this to a friend. Possibly even an enemy. It might help them be my friend.

So comfy! Def recommend this bed!! It’s very comparable to the nectar mattress!! I have a king nectar and bought this one in a full size and the comfort level is identical!

I ordered my Zinus online from Sam’s Club. My mattress came frozen and has yet to reach a full 12” after two weeks. It is a heavy mattress and would’ve impossible to send back or return to a Sam’s Club. Hoping it will slowly expand to a full 12”. We have purchased three of these mattresses over the years but first one from Sam’s

I had a friend who has this exact mattress and was really impressed with it while house sitting at their house. I got mine in a timely manner and so far so good. Seems my body was a little stiff for a couple days adjusting to it...but now it's great!

I was surprised how comfortable this mattress was! It came in a vacuum sealed bag and needed to rest 24-48 hours before being ready for use, but it was worth the wait. I prefer a pillow top mattress, but found the foam to be a better alternative. It conforms to my body and I don’t wake feeling stiff or achy.

We've bought several of these as the kids grow out of their twin beds. The foam mattress is liked by all. We're up to 4 now and they've held up over the years. Very nice, good value. Come vacuum sealed in a box. We also got the higher smart base with room underneath for storage.
