At Kleinsleep, we expect all of our mattresses to supply comfort and support for at least 15 years, and we back that up with a 15-year Non-prorated warranty.

The Kleinsleep Alder is a high-quality mattress with proper support for the master bedroom. Old-school construction provides great pressure relief, which leads to a solid night's sleep. This mattress uses an organic GOLS-Certified cotton cover, ensuring a cool and dry night's sleep.

This pillow top mattress has an ultra luxurious surface, with firm support at its core. The Alder is designed to contour to the natural shape of your spine. If a ten were the firmest, this would be a 3. Feel free to contact one of our sleep experts at 203-846-2233 to see if the Alder is a good match for you.
