## Customer Reviews

### ⭐⭐⭐⭐⭐ Love this mattress for a perfect nights sleep!!
*by D***L on June 22, 2025*

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

### ⭐⭐⭐⭐⭐ Expensive, but absolutely worth it
*by M***N on May 9, 2024*

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.

### ⭐⭐⭐⭐⭐ Comfort
*by F***Y on April 1, 2025*

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