Great FIRM Mattress!

[This review was collected as part of a promotion.] This is a GREAT mattress! It’s firm, so if you need that, this is what to get. We tested it out and both my husband and I agree it’s a high quality product. I like how thick it is too. I have been using a more expensive mattress and this is on par with higher cost mattresses for sure!

Great mattress

[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.

Really comfortable!

[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.

Super comfortable

[This review was collected as part of a promotion.] This mattress is so comfortable! It has to be one of the most comfortable mattresses I've ever owned. It's firm but still gives great support to my back and hips. The price is great for this mattress. It really feels like this mattress will last a long time and be very durable. Even my 6 foot husband finds this mattress super comfortable. We haven't had any "holes" where we sleep either. It keeps its form and doesn't sag anywhere. I would definitely buy another one of these mattresses in the future.

Best mattress ever!

[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.

Firmly Certain About Serta's Mark

[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!

Good back support must buy

[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

Firm and supportive—took some adjusting, but worth

[This review was collected as part of a promotion.] I gave this mattress to it my daughter, and it was noticeably firmer than we expected. It took her about two weeks to fully adjust, but once she did, she started sleeping much better. The mattress provides excellent support and seems very durable so far. While the firmness might not be for everyone, if you are looking for a mattress that holds its shape and does not sink, this is a solid choice. It also regulates temperature well—no complaints about overheating during the night.

Amazing mattress

[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.
