softer than expected

We had read the ratings of softness of 7. 8/10, but find that the mattress seems much softer that expected. . Even getting in/out the edges mostly compress. We may try to find a firmer topper to add to it, although that will make it too tall perhaps.

We've bought this mattress twice.

We've bought this mattress twice. Loved it the first time I purchased it. The 2nd time, felt a little different. But, after two weeks, I am sleeping just fine and am glad I bought this again.

Highly recommend

[This review was collected as part of a promotion.] I was looking for a new mattress due to starting sciatica and plantar fasciitis issues. One of my friends suggested Casper because she was so happy with her purchase. I looked into reviews and compared prices of other mattresses and decided to try it out. So happy I did! 2 years later and it's still the best sleep ever. No more pain. No more tossing and turning. Highly recommend this bed.

Amazing Foundation

Extremely sturdy and good value for the price. Had on older foundation for a smaller bed for 6 years and it still looks new and holds up. Highly recommend to anyone needing a good and strong foundation for their bed.

Best pillow

I have been looking for a new pillow for a while and finally found them! Casper pillows are soft while also keeping their shape throughout the night. I love them! Highly recommend.

Comfortable support

My son has a Casper that I sleep in when I visit. It impressed me so much that I had to have my own! It supports my back and hips so well without creating pressure on them. I’m very happy and I’m sleeping so much better now!

[This review was collected as part of a promotion.] mattress is comfortable at first but starts to get a little hard and uncomfortable after a few months of sleep

Dollar for Dollar

We reviewed several mattresses from multiple review sites. We finally subscribed to Consumer Reports and their evaluation confirmed everything we had thought. The One is the best memory foam mattress for the money. Its edges have decent support. The motion transfer is minimal. We’re both side sleepers and we love it. The sides have enough support to not roll when you near the edge

Comfiest mattress I’ve ever slept on

[This review was collected as part of a promotion.] I originally bought this bed because of my friends raving reviews. My back doesn’t hurt in the mornings but I still have such a hard time getting out of bed each morning because this bed is so very comfortable!!
