First time I laid on it seamed kind of firm. However after sleeping on it for several months now I love it. Very comfortable. Never wake up with any aches or pains. I actually look forward to going to bed now. Works for my 225 lbs.

If this is considered medium firm, I'd hate to see what firm is. I've had this for over a month and its still hard. Not at all what i thought memory foam would be. My kids both have memory foam mattresses and they are super soft and comfortable.

My daughter bought one for herself. We tested it and loved it so much we bought another one for my son. My dad loved it so much that he bought one for himself also.

Loved the convenience of buying/transporting a mattress in a box. Set up was a breeze. Very very comfortable for sleeping. Can't review the longevity as it is a recent purchase, but our first impression is excellent.

Title is misleading. This mattress is very firm. In process of waiting on serta or Sam's to reply back to me about returning it. Guess we will see how that goes.

We bought this mattress this month (October 21). We took it out the box as instructed waited 48 hours to see if it would reach the 12 inches, no such luck. Serta put a 10 inch mattress in a 12 inch box either by mistake or on purpose. I would give 5 stars if it was not for this situation. The mattress sleeps good, no more back pain!!!! Now struggling if I should return it!! I feel cheated!!!

Help! I bought this mattress Friday and I set it up Friday night. It’s been over 48 hrs and it has only expanded to 10 inches. It’s super comfy and I hate to call Sam’s about it but I did pay for a 12 inch. I’m so torn! I wonder if I have to give it more time..

I've had lots of problems finding a mattress to where when I get up in the morning I feel my back pains. This is the only mattress that I wake up with no back pains! I'm so pleased with my purchase! It's like sleeping on a cloud and for being sold at a low price! Highly recommend.

Bought this last week, slept on it for a week. too soft for me.

Very comfortable for the price
