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.

Nice quality but would not recommend for an adjustable bed. When the head of the bed moves upward the top cover of the mattress creates a roll of padding.

This is the second of this mattress that I’ve lurches and I couldn’t be happier. It’s such a comfortable feel and gives me the support I need. I am very happy with this purchase.

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.

This mattress is so comfortable. Doesn’t take long to expand and no odor. I bought one for each of my children and quickly bought myself one as well. It’s like sleeping on a luxury hotel bed.

Bed is supposed to be medium-firm. It is real soft. When we unrolled it, there was a gold of fabric that will not lay flat. We are returning this mattress.

Mattress is comfortable. I bought 2 for each of my kids going to college. Although, the end of both mattresses are sunken in and will not totally flatten out like the top of the mattress. I suspect it is how they were packed.

Very easy to deal with. Delivered to our home and then open box. Unroll and cut plastic, wait for the mattress to inflate. Very comfortable. We own a king and two queens now.

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.

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)
