High quality mattress

[This review was collected as part of a promotion.] Very comfortable firm mattress high quality material and thick could be used without box spring. Great support if you need a firm mattress. I was surprised at the value for the money. Definitely recommend

Bed so comfy even the babies passed out fast

[This review was collected as part of a promotion.] I cannot praise this mattress enough! I have scoliosis and with that comes constant back pain. The soft pillow top I had before did absolutely nothing to help with my back pain. After 3 nights of sleeping on my Serta my back pain has lessened and my sleep has improved. I never realized how much my sleep was impacted until I got a better mattress. I can not recommend it enough, even my toddlers fell asleep right away on 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.

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!

Nice quality

[This review was collected as part of a promotion.] For its price, the firm Member’s Mark/Serta entry-level mattress delivers solid support and basic cooling. It’s a strong pick for back and stomach sleepers on a budget. But if you need a bit more cushioning or expect heavy daily use, consider something slightly softer—or be prepared to add a plush topper.

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.

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.

Firm like they claim

[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
