[This review was collected as part of a promotion.] We upgraded my teenage niece to a larger bed with this Serta Members Mark firm queen-size mattress. She is so happy with it and said that for the last week, she's had the best sleep ever! It is breathable with a soft gel and high- density foam.

[This review was collected as part of a promotion.] I’ve been using the Serta Member’s Mark firm mattress for a few weeks now, and it’s made a big difference. After long hours on my feet at work, I used to wake up with back pain but not anymore. This mattress gives the right amount of support and comfort for a truly restful night. I finally wake up feeling refreshed and pain free. Highly recommend it if you need firm support and better sleep.

[This review was collected as part of a promotion.] This is an AMAZING value! It's so comfortable. I slept like a baby and I don't usually sleep well. It's super firm but also really soft. It's great on my back and helped a lot with my chronic pain throughout the night. It kept me cool as well and prevented me from getting all sweaty.

[This review was collected as part of a promotion.] The serta firm mattress by member mark is excellent for a restful sleep. It has enough support built in that it is perfect for your body. My back does not hurt when I wake up from resting on this bed. The pillow top is so soft and feels cushioning on top. The mattress is much nicer than the mattress in a box versions available. I highly recommend this if you like a firm support mattress.

[This review was collected as part of a promotion.] There was an error in the original shipping day, truck broke down, so we got it a bit later. I would like to take more time before a full review but so far can say it seems pretty comfortable! I'll update in the future.

[This review was collected as part of a promotion.] This mattress is fantastic, the thickness is fabulous, and the firmness is great. It is thick enough to raise you up higher off the bed. I suffer from terrible back pain and with this mattress I have had hardly any.

[This review was collected as part of a promotion.] I have been using this mattress for a week now and I have to say this was a great deal! It’s not firm and it’s not soft- it’s right in the middle for me to get a good nights sleep. Once it arrived I laid it out as per instructions and it literally took less than 24 hours to come into form. I love this mattress - it was a pleasant surprise.Back support temperature regulation

[This review was collected as part of a promotion.] After receiving this mattress, I put it on the new bed frame to try out. It's amazing, and I really loved it. I like a firm mattress anyway, but on this one, I felt completely supported while it maintained a soft feel as well. For me, a good night's sleep automatically equals an excellent value, and that's what I got. Now I just need to get the king size version also!

[This review was collected as part of a promotion.] First, thank you! Skeptical as most mattresses are too soft. This is the exception! Nice and firm. I love it. Used before we turned on AC, no sweating,or shifting sheets. I find myself not tossing and turning, not sinking into a squishy mattress. So nice to lay down and it is firm. Passed the bouncing test as my 2 yr old granddaughter gave it a try. It did not show indentation where she walked and bounced. I can climb on it and it doesn't sink in. I am very pleased and thankful.

[This review was collected as part of a promotion.] I slept on the Serra Members Mark Firm Queen mattress for a week. It is a firm mattress for sure! It’s wonderful if you like that. I’m always looking for the right mattress. While this one was too firm for me personally, the quality is amazing! Made very well! I will be placing it in my spare room for guests to enjoy
