As a 65 Kg (144 lbs) stomach sleeper who occasionally switches to side and back sleeping, I decided to try the Casper Original mattress. Here's a detailed account of my experience:

Ordering & delivery: I placed my order on Casper.com (Mar 18) and was pleasantly surprised by the quick delivery, receiving the mattress just a few days later (Mar 21).Unboxing & setup: The box was quite heavy, making it difficult to handle alone, but I managed to unpack and set up the mattress without assistance.

First impressions: Upon inspection, the mattress showed an unusual firmness in the middle third and softness at the head and feet thirds. Although that difference in firmness felt odd to the touch (like there is a concrete block somewhere under the middle third), it proved to be comfortable to lie on.

First night: My first night on the Casper Original was a welcome change from my old, worn-out IKEA spring mattress, resulting in a restful and enjoyable sleep.

First week: Throughout the first week, I would say my sleep quality was consistently good, and I was quite satisfied with my purchase.

Second week & emerging issues: However, in the second week, I started to notice the mattress slept hot, and it softened significantly overnight as my body heat transferred to the mattress (most likely the memory foam softening as it was heating because I noticed it was nice and firm in the evening when the bed was still cool). The most affected area was the middle third, which lost support as the night progressed.

Worsening issues: As weeks went by, the mattress continued to soften at night and I began experiencing lower back pain. This was likely due to inadequate support in the hips area for my stomach-sleeping position.

Decision to return mattress: Early this month, after another poor night's sleep and lower back pain, I concluded that the Casper Original mattress wasn't suitable for my needs, and I decided to look for another option. I did my homework prior to purchasing the Casper mattress so I had a second option, although a pricier one (I chose a Novosbed firm mattress, which so far has provided the firm support and pressure relief I was seeking).

Returning the Casper mattress: I called Casper support today to schedule the return. The customer service team was helpful and made the process hassle-free, barely asking why I wanted to return the mattress (I hope they'll later ask for my feedback). The return is set for tomorrow via Got-Junk, and my refund will be processed once Casper receives proof of pickup.

In conclusion, while the Casper Original mattress initially offered comfort and quality sleep, it ultimately failed to deliver consistent support overnight, especially for a stomach sleeper like me. If you're considering this mattress, be aware of potential heat and support issues especially if you're a stomach sleeper, and make sure to take advantage of the return policy if it doesn't meet your expectations.
