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

Love this mattress so comfortable. Our second Casper. Will never sleep on anything other mattress!!

Just purchased in March, loving it. Very Comfortable. Feel am sleeping better than the King Tempur-Pedic I replaced with the Casper

All of my dads side of my family (including myself) suffer from chronic back pain, we're also mostly above 6' tall (I'm 6'6 lol) and have struggled with severe pain since I was a kid. Growing up, and until now I had typical hybrid mattresses with coils and whatnot. My neck, shoulders and back would all be stiff when I woke up. Not with Casper. It's an absolute game changer if you struggle with pain or sleep in general. The top layer is extra soft for your pointy bits, but is still extremely supportive. I've never experienced this much comfort in a bed before. It costs a pretty penny, but in my opinion, it's worth every cent.*It is on the softer side. So if you prefer a stiffer mattress I'd recommend going up a level.Thank you, Casper.

The Caspar Original is advertised as a medium-firm memory foam mattress. While there is no standardized rating system for the firmness of a mattress, of the various memory foam and innerspring mattresses that I've experienced I would categorize this as a soft mattress. I haven't tried the other firmness designations of Casper memory foam mattresses so I can't speak to how their medium-firm mattress compares against what they would call firm and soft (I couldn't find a description of firmness on their site nor any product labeled 'firm' or 'soft') but to my body this is a soft mattress. That doesn't mean bad, it is very comfortable, it's just out of line with how most other memory foam mattress manufacturers use of the term 'medium-firm'. It is a very comfortable mattress and unlike many other memory foam mattresses does not even mention needing to let the mattress expand fully over a number of hours or even days, nor is there any talk of odors of any kind, only that it is ready to sleep on as soon as it is unpacked, which in my case I did. There was only the smell of my own worn socks which I could have done without if I had only thrown them in the hamper instead of leaving them on the floor next to the bed... It's a great mattress but it should be understood that it may seem soft to by comparison to other mattresses labled as 'medium-firm'.

This mattress is the best I’ve ever slept on - I’m saying I actually get a good nights sleep. I have pain in my back and pain in my hips never really comfortable before this dream mattress came along. I set it up alone and it was Super easy and a fast set up. I also purchased the foundation https://a.co/d/33ZXfKQ with Amazon FYI it will fit inside a queen size bed frame!! I couldn’t be happier with this purchase ❤️

Absolutely hated this thing. Got it in 2020 during Covid. Great time to get it- because when I decided I didn't like it during the trial period, the company told me they couldn't send anyone to pick it up and to keep it. Put a 120 dollar memory foam topper on it and have used it since- but without that topper, this thing was like sleeping on a coffee table.

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.

There's not really much to write about this mattress, except that it's wonderful and that after two years, it still holds up and it has been amazing for my back in my spine. I highly recommend this product!
