I wish they had mattresses set up to test for firmness. Our mattress was a little too soft. It's very comfortable to sleep on, but when you sit on the edge it feels squishy. We purchased the medium firm.

My daughter bought this mattress for a daybed. I slept on it all week for my visit. The mattress was so comfortable! I highly recommend this mattress.

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.

The mattress took just about 3-4 hrs to be at its full potential! It’s was supper soft the mattress molds to you like a glove. My fiancé and I could barely wake up we were getting such good rest.

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.

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.

The bed is OK for my almost 6 year old son. He is a slim kid, so for him it is fine. For an adult a medium feel, maybe not so much. Maybe a firm would have been better. For now the bed will do.

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.

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

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)
