it is not 12 inch, like they said, it is about 10 inch. It is lumpy and not comfortable at all.

Great!!! Got for a guest room that our son stays in when he visits. He said it was great.

Super comfy mattress and so glad I purchased.

Memory foam but is not very firm. It does NOT feel supportive at all

We purchased this mattress with the adjustable base and now sleep soundly.

I bought a twin size to use on a platform bed in my she shed. It's perfect and so comfortable.

I like this Member Mark Mattress...it sleeps good

Very impressed with this mattress! Extremely comfortable and quality appears high.

Very comfortable fun to watch when it gets unwrapped.

2 months in, a crease in the mattress that doesn't go away. it was given 3 days to fully expand before we used it. Not sure what to do with it.
