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.

So far so good

[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.

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!

Perfect balance of firmness!!!

[This review was collected as part of a promotion.] This mattress is a win for me. It's very comfortable and has the perfect balance of firmness but at the same time soft. I've used it for quite some time and haven't felt any discomfort upon waking up; on the contrary, I woke up feeling very rested. It's high quality, and I love its thickness. I really recommend it.

Comfortable

[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.

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

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.

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.

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!
