This is the second foam style mattress that we have purchased. We have the King Serta 12" Sleep-To-Go mattress in our master bedroom, which we really like and have had for over two years (also purchased at Sam's). We wanted to save money on a mattress (queen) for a spare bedroom, so we went with the Members Mark brand this time. It was pulled out of the package yesterday early afternoon, but after about 8 hours of expanding, it still appeared very lumpy. The edges are not expanding much and the mattress appears to be closer to 8-9", not 12" as advertised. I opted to sleep on the new mattress last night to test it out. This morning when I woke up, I felt I was sunken half-way into the mattress. I'm 6' and 215lbs. I've never had any issues with other mattresses in the past. The mattress is VERY soft, nowhere as firm or supportive as our Serta. I will give the mattress another 24 hours before returning it or contacting customer service to get any issues resolved.

First we purchased one for our toddler’s big boy bed. After trying it out for a month we ended up buying another for our own bed. For a foam bed, it’s pretty great. I’d like to see the edges more firm but that seems to be a problem with foam beds in general.

After getting an adjustable frame decided time to change mattress. Biggest problem was getting the old one off and ready for disposal and getting the plastic off the mattress was bit of challenge being careful not to cut the mattress. Once in place it began to hiss and start to expand quickly. Was surprised it only took a few hours to expand to 11 of its 12 inches! Very comfortable. Have seen reviews saying too soft but they must like sleeping on a rock as this is advertised as medium firm and would say that is right. So far so good and if run into problems in the future will come back to amend. So far very pleased.

The mattress is comfortable. I’m giving a rating of two stars because it wreaks of chemicals. It still smells just like it did the day it came out of the box and it’s been two months. The information pamphlet says it should stop smelling a few days after we unbox it. We have to air out the room daily.

We purchased a full-size, firm mattress for our spare room in February. It's now June. I waited to leave a review, so I had plenty of time to try it out. It is definitely not firm. I sleep on it 5 nights a week. It's soft, and your body sinks. It might be firm for a child, but anyone over 100 pounds would not say it's firm. Would not recommend or buy again. .

It’s way to soft .. you will sink unless you sleep in the middle. Worst buy ever.

This mattress is a little softer than I thought it would be.

Love this mattress! The negative reviews did bring a bit of concern but this mattress is amazing!

The mattress is quite a bit softer than advertised.

Very comfortable. I wish it was just a tad firmer, but comfortable nonetheless.
