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.

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.

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

Perfect mix of comfort and cool

[This review was collected as part of a promotion.] It was absolutely awesome that I got a new mattress to review. I needed a new one in my guest room, and as I write this my brother and sister-in-law are sleeping on it. They say it is very comfortable and they don't sleep hot on it. My sister-in-law has also had bad back pain as of late, but she is very complimentary on this mattress. They are looking at buying their own when they go back to Colorado. Thanks, Serra and Influenster!

Comfortable quality mattress

[This review was collected as part of a promotion.] I just can’t say enough about this mattress. This mattress is so comfortable and has exceeded my expectations so far. It's only been about 2 weeks since I received it but so far this mattress is exactly what I needed. It strikes the perfect balance between support and comfort, firm enough for proper back support but still soft enough to feel cozy that doesn't need a mattress pad/topper as the matress is thick. Great for side sleepers or your back. When I get up in the morning the mattress does not sunk in. It definitely holds it’s shape well and with this bed it makes it hard to get out of it. The level of comfort is unmatched. I also have been suffering from back, side and neck pain for many years which has been preventing me from sleeping all through the night. So I struggled to find anything that can fulfill my needs. After sleeping on my new mattress for the first time, my back and neck pain was surprisingly relieved. My hips don't feel sore when laying on my side and I feel no more aches and pains in the morning. I am now sleeping better and longer. I love this mattress. This mattress has been a game changer. It’s great for my back, hips, and neck. I have no complaints. This mattress has been a dream and am very happy with it. 5 stars!!!

An affordable mattress that feels like luxury!

[This review was collected as part of a promotion.] My 10 year old son, who is on the spectrum, just got his first big boy bed with the SERTA Members Mark Firm Queen Mattress, and it has been a game changer. He proudly made the bed himself, complete with his pillows and stuffed animals, and told us it was the best he’s ever slept. That kind of comfort and confidence means the world to us. The mattress strikes a perfect balance between firm support and overall comfort. It offers great back and body support, which helps him feel secure and well rested. The firmness is exactly what we hoped for, not too hard, but definitely sturdy and reliable. One thing that stands out is how well it regulates temperature. My son tends to sleep warm, but he’s been sleeping through the night without getting overheated. It also feels durable and well made, like it will hold up for years to come. For the quality, comfort, and peace of mind it provides, this mattress offers incredible value. It’s a great choice for anyone who needs reliable support and comfort, especially for kids who need consistency and restful 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!

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.

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
