CasperSleep Original Foam, King Size Mattress with Zoned SupportTM - Medium Firm Memory Foam Bed in a Box - 100-Night Trial - 10 Year Warranty - CertiPUR-US Mattress, Light Grey

The mattress has been wonderful for my husband and I. We sprawl out when we sleep, and can't sleep if we're touching each other, and also, with a baby on the way, I need lots of pillows to stay comfortable. The mattress is perfect for all of that. HOWEVER, we're new at purchasing mattresses, and bought it based off of the common review that it wasn't too firm or too soft, and slept cool. We have a different opinion on that. If anything, the purchase has taught us that we prefer a firmer mattress with even MORE of a cooling element, which this is lacking on. BUT, overall, the mattress is great, soft, and fits our need of space.

This is a nice bed we went from a sleep number to the Casper and it is very comfortable and surprisingly not hot!

Purchased 3 Casper mattresses and they will not expand correctly. These are like seconds in my opionion Two of the mattresses the corners are not square and not fully expanded. My phone experience with Amazon was terrible. They do not send somebody to pick up the mattresses to be returned. Not sure how they expect us to take 3 king sized mattresses to a courier. When I asked the customer service lady very nicely how this was feasible she explained the same thing over again and told me she would disconnect the call which she did. I am astounded at their lousy service. Buy Casper in an actual Casper store!

A couple of years ago I replaced an extremely soft traditional spring mattress (that had become severely warped) with a middle-of-the-line Ikea foam mattress. The Ikea mattress, at least on a boxspring (as opposed to slats or directly on springs) was unbearably hard for me. I am overweight, and when I would lay down on my back on the Ikea mattress, my lower back would arch several inches over the mattress. I developed very frequent lower back soreness because of this. I finally had enough of the Ikea mattress, so I started researching alternatives, with the limitation that because of the pandemic I wouldn't be able to try out any mattresses at a store. Also, because of my very narrow stairs, I knew that the only King size mattress I would ever be able to move back downstairs when needed was an all-foam mattress (so hybrid options were out of the question for me).I researched mattresses extensively for a few weeks. I started with Consumer Reports, which rates Casper's mattress very highly. I read and watched review after review online. I also asked my friends on Facebook what mattress-in-a-box they recommended, and a friend wrote to say that her guest beds are Caspers and that her guests always mention how comfortable they are. I finally settled on the Casper original (all-foam) and I couldn't be happier. I find it very supporting and I like that I don't sink into it. It's funny to see some reviewers on here write that it's way too firm, and others say that it's way too soft. I think it's a pretty perfect balance of softness and support. I am very happy with my purchase and I would highly recommend it.

I like it but can't sit on the edge of it. I don't like that part.
