It is very comfortable. Didn't have a smell as some other reviews mentioned. We left it to "rise" for 48 hours. First night on it, I slept all through the night, which I haven't done in years. It's not too soft or too firm.

The mattress is comfortable and fits my needs in a spare bedroom. I have napped on it several times and have really found it worth the price. I am thinking about ordering a King size mattress for my masterbedroom.

We get great comments on how comfortable this bed is from guests who stay at our glampground. I believe it is right in the middle ground for most types of sleepers. We have one in all 4 of our dwellings.

First bought a twin for my semi truck, then I bought a king mattress for my house and now this twin is for my Great Dane/ Great Pyrenees mix. She loves her new bed and her flannel sheets with a mattress warmer.

Member's Mark 12" Firm Memory foam mattress is exactly what I've been searching for in a mattress. It's consistently firm across the entire mattress and does not sag in the middle.

Bought this for the guest room at my parents hoping it would be better than the rock hard, lumpy mattress they had. Best sleep we have had in weeks. Spent 4 nights on it and now are considering replacing our mattress

We bought the "medium" firmness mattress as that is the only firmness Sams sells in the store, and we needed the mattress quickly before guests came to visit. It is softer than i would like, but is still comfortable.

I was hesitant initially about a the brand, once I got it home let it settle. WOW what a difference this bed helped my back so much ! Only down side it’s bigger than my box spring.

Medium was pretty firm - my husband loved it and HATED the Firm. The Firm was like laying on a plank of pine wood with a blanket over it. The Ultra Plush works well for me - soft enough to sleep, where the medium was a bit on the firm side for me.

This was bought for my 88-year-old petite mother. She has an adjustable-head bed. She said this is the most comfortable bed she has ever had! We are very happy with this mattress and recommend it.
