Very comfortable, never slept better.

Too soft to be called firm

I bought this to replace a bed in our spare bedroom and combined with an adjustable base. At first I thought this bed was too hard. We have had a few guests sleep over the past month and I have tried to sleep in the new bed a few more times. I now find the soft side of the mattress very comfortable; combined with the vibrations of the adjustable base, I fall right asleep. It also has a 10 year warranty. Definitely a good purchase.

We bought the Member's Mark adjustable split king base and these mattresses to go along with it. All in, we spent $1k less than all the competition. This is the most comfortable mattress I've experienced thus far. Can't recommend this enough, I'm sure the price will be increased on this thing in the future. $350 is a killer deal.

Really nice ! I really that it can be flipped not just corner by can flip over.

We love this mattress and considering buying another in a King size!

This is very firm and comfortable. Love that it’s a flipable mattress.

Very comfortable . Feel rested and revived.

My purchase was wonderful. Arrived before time, bed is comfortable, yet sturdy enough for great support. Thank you Sam's Club for doing exceptional business. I appreciate you!

Have had it for about a month, pretty comfortable and have slept well. My only complaint is that it's not marked which side is firm and which side is less firm, a little hard to tell by just feeling with your hands.
