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

This was our first purchase of a mattress in a box. Our guest slept on it for two nights and loved it. The cooling gel kept her cool throughout the night. This mattress works great on the Member’s Mark adjustable base.

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.

Just enough softness without being to firm… only complaint is that has a slight loose, wrinkle that didn't fill out completely but doesn't effect comfort…. To heavy and a little difficult( once out of box ) to exchange

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

there is an obvious defect with this mattress, but Sam's will not pick-up or refund because I picked it up curbside. I have no way to return it without renting a truck. HORRIBLE - stay away (see pics)

Comfortable firm mattress, with more edge support than a nectar. Normally purchase Casper, but this was immediately available, and hundreds less. Not light weight lol. Bought a 2nd one, if that says anything.

We purchased this mattress for our bed at our camp. Extremely comfortable. No additional mattress topper needed. Considering purchasing one for my daughter's bed.

Super comfy! Cant beat the price especially during the Memorial Day sale. I considered one of these for a couple years and finally did it, like sleeping in a luxury hotel now.

I bought this mattress but haven’t slept on it yet. It smells like glue or chemicals . I aired out the room , turned fan on, opened windows, put deodoranizer on plug and it still smells.
