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.

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!

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.

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.

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.

Sam’s is a really professional company. I have had experience with this type of mattress without a problem. I feel confident Sam’s will and has been assisting me in this matter. Sam’s was my go to for my business purchases for over thirty years.

So far it’s been a great mattress. It’s firm - I had been using a memory foam gel topper but it had lost its firmness after years of use. Have not noticed any odors or excessive heat. “Inflated” to its full thickness within hours. Fits VERY snug into platform bed frame. Very pleased with this purchase

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.

First time I order a mattress that comes in a box. It was interesting to see it unfold. Instructions on how to open the mattress bag were simple and easy to follow. Only reason not giving a 5 star, because it didn’t go up to 12 inches. Only 10.5 inches. I have had it for a week now.
