We have been using our king-size Casper Dream mattress for 2 weeks, and it is great so far. I have back and neck issues, and this mattress, along with a pillow designed to support the cervical spine, has helped me tremendously. Yay!
So, far, so good! I had the delivery service, and I cannot recommend these men enough! I am sixty-five years old and suffer from arthritis in my back. I opted for the hybrid mattress. It is wonderful!
