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!

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!

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.

I never thought a firm mattress could be this comf

[This review was collected as part of a promotion.] I lam in love with this mattress. I was a little hesitant with a “firm” mattress, but I have mold back problems that I could tell my old mattress wasn’t helping with. Stomach or side sleepers, this is a great mattress. Firm, pillowtop, breathable and comfortable. I have been using for five days now and notice I get a good and comfortable sleep. Mattress is high, but not too high and my queen bedsheets fit perfect.

That Serta Member's Mark Firm Queen mattress is aw

[This review was collected as part of a promotion.] The Serta Member's Mark Firm Queen mattress is seriously impressive—it’s got that perfect mix of comfort and firm support that makes it easy to fall asleep and wake up feeling great. The comfort level hits just right: it’s firm enough to support your back but still cozy enough to relax into. It’s built to last too, with great durability that holds up night after night without sagging. One of the standout features is the temperature regulation—it stays nice and cool, even if you tend to sleep warm. When it comes to value for money, this mattress feels like a steal; you’re getting top-notch quality without the luxury price tag. And in terms of support, it keeps your body aligned and pressure-free, which is a game-changer for better sleep.

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.

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.

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

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.
