Super comfortable

[This review was collected as part of a promotion.] This mattress is so comfortable! It has to be one of the most comfortable mattresses I've ever owned. It's firm but still gives great support to my back and hips. The price is great for this mattress. It really feels like this mattress will last a long time and be very durable. Even my 6 foot husband finds this mattress super comfortable. We haven't had any "holes" where we sleep either. It keeps its form and doesn't sag anywhere. I would definitely buy another one of these mattresses in the future.

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.

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!

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!

Love the firmness

[This review was collected as part of a promotion.] First, thank you! Skeptical as most mattresses are too soft. This is the exception! Nice and firm. I love it. Used before we turned on AC, no sweating,or shifting sheets. I find myself not tossing and turning, not sinking into a squishy mattress. So nice to lay down and it is firm. Passed the bouncing test as my 2 yr old granddaughter gave it a try. It did not show indentation where she walked and bounced. I can climb on it and it doesn't sink in. I am very pleased and thankful.

Great mattress, especially at its pricepoint

[This review was collected as part of a promotion.] A very comfortable mattress that seems durable and a great value for its price. It is not too soft, not too firm. It was not difficult to unpack or put on the frame. It was easy getting sheets on it as well.

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.

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!!!

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.

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.
