Two nights used and it created a wrinkle in centre.

If firm is this soft, I would hate to imagine sleeping on the ultra plush. This mattress is so soft it is ridiculous. softer than my soft old foam mattress. returning as soon as possible. if you like soft mattresses that come delivered in an easy box rolled up- this is for you.

I bought the medium firmness in store and it feels like plush. Too soft. Perhaps if I had bought the firm, which they don't have in store, it'd have worked. But they won't ship to CA. What a shame, I really wanted to like it. On the plus side, it did not smell bad. And the quality seems to be very decent for the price.

I ordered in app and did a store pick up. This is NOT hotel premium as described. I received a regular Members Mark 12” mattress. I did not realize it until it was too late, I had it out of the box and the plastic was off. I would not have accepted this at the store if I had known. I actually passed up this item in the store wanting the better “Hotel Premier” product. Sam’s Club misrepresented this product and it’s too late for me to return, I had no way of getting it back to my vehicle after it was unrolled. I’m very disappointed

Felt more like soft rather than medium firmness. Way too squishy for my liking.

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.

Very poor support for regular-sized adults. Adults sink through all the way to the bottom of the mattress. It’s not terrible for kids because of their weight, however.

I wanted to try it because it was such a good price but I only had for a few days and used the hydraulic base once and mattress top material got a wrinkle in it that wouldn’t go away once flattened out.

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

This might be a very good mattress if it fit. This Twin XL is 40 inches wide. The Mattress will not make Split King (4 inches of overhanging for the pair). NOT GOOD
