  • Heavenly Sleep
Size: California King Style: Element
I tried this mattress at an AirBnb and cannot wait to sleep on it every night. Been looking for years and this is the one.

  • So far so good 😊
Size: California King Style: Element
I was in need of a new bed I had an old Queen one that had just been beat up to death for the past 4 years.... After much online research and review reading I came across this one let it sit in my living room for about a week in the box procrastinating on setting it up but I finally set it up and let me tell you my back feels really good 👍🏾👍🏾 ... All update the review later as I just open this and I've only been in it for about 2 hours but I'll get back to you guys... ... show more

  • 100 days, yeah right... Save your money and time.
Size: California King Style: Element
Don't bother. Ours has a huge hump down the middle from where it was folded before being rolled up to put in the box. Beware of the 100 day trial... I left mine in the box for a few weeks before opening it and now that I want to return it, I can't because I'm at 108 days. If you buy these mattresses from Amazon, even from the Casper store, no one at Casper will talk to you. Your return have to go through Amazon but Amazon won't let you return it. It's a scam for a crappy mattress. ... show more

  • Didn't last 3 years
Size: California King Style: Element
Purchased in August 2021. Loved it, everything was terrific for the first year. Rotating as directed. In the second year, noticed a sag near the head of the bed, the base of the bed was just like new. Started to wake up with back pain from the "flimsyness" (I know that's not a word). By the third year, it just completely sagging at the head with even light pressure. The base is still as good as the day it came. So basically, I have a U shaped mattress. Tried to use the Casper "10 year" warranty, they said that since it doesn't have a visible 1" sag without load it is not a defect. Geez, I sit on the head of the bed and it goes from 12" to 3" (that's what she said), on the base it goes from 12" to 11.5" (as it should). Now if that is not a defect, I don't know what is. Horrible customer service. $750 down the drain. PS. I'm 6'4", 200 lbs, and using a proper platform base to support the mattress. And Casper is not a friendly ghost. ... show more

  • Comfortable and easy set up
Size: California King Style: Element
We have used this product for a little over a week now and really like it. It replaced our older (12 year old) Sleep Number California King mattress. We opened the Casper California King mattress in our 40 year old water bed frame and it fit perfectly. We put the rolled up mattress inside the water bed frame, unwrapped the mattress and got out of the way while the mattress expanded for a precise fit in the water bed frame. ... show more

  • Nice mattress
Size: California King Style: Element
I do like it so far . It does have an odor to it but it will probably be gone after a few days. It expanded quickly. It’s on the soft side.

  • Casper Element
Size: California King Style: Element
Best sleep I have gotten in a very long time. Very easy to unbox and since it's vacuum packed, it takes no time to become the best mattress I have owned.
