I wouldn't be surprised if it's also on sale.

Naplab [naplab.com] "The Casper Cooling Select is available in a single firmness, 6 out of 10, and with a medium-firm feel."

Mattress Clarity [mattressclarity.com] "Medium-Firm 7/10. Its medium-firmness offers the right amount of support to average and lightweight sleepers to achieve neutral spinal alignment. This mattress has a balanced-foam feel. The top comfort layers make the mattress feel soft yet responsive, and its base support foam layer is much firmer to elevate the lumbar region."

Sleepopolis [sleepopolis.com] "Overall, I gave the Casper Select a 7 out of 10 on the firmness scale, which is just a bit firmer than the industry standard for medium firmness of 6.5."

Sleep Foundation [sleepfoundation.org] "With three layers of foam and a medium firm (6) feel, the Casper One is designed to relieve pressure and support sleepers without feeling too soft."

Medium. The hybrid version of this is more firm.

Recommend getting the firmest foam mattress you can since all will soften over time, especially at this price point.

Just FYI last time I tried Casper it was insanely soft despite it being called medium firm. We need some concrete density specs to compare mattresses.

This bed literally took away my back pain. Highly recommend it. I just bought another, will be requesting a price adjustment. Thank you for this post.
