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.

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.

I was skeptical about buying a bed in a box, but what a great decision! My wife is disabled and has sleep issues but she is actually sleeping better now. I’m so happy I decided to take a chance on 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.

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.

Not too soft, not too hard. Medium firm is the correct description for this mattress. This is the 2nd one I have purchased - 1 for our guest bedroom (full) and 1 for my grand-daughter (queen).

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.

It was a gift for my 93yr old mother who wasn’t sleeping. This was perfect for her paired with the mechanical base. She is very comfortable and sleeping now! Thank you Sams club. You never disappoint!

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.
