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.

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.

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

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!

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.

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

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.

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.
