The beds built here at Deep Creek are designed specifically for mail-order mattresses (like Casper, Tuft & Needle, Purple, Leesa, Nectar and the like), but they work great with traditional spring mattresses, too.
While it is true that foam mattresses can lie on a normal bedframe or boxspring, foam mattresses do require good airflow to the bottom of the mattress. I, personally, have experienced mold and mattress discoloration due to improper ventilation. That led me to design these beds—to maximize comfort, airflow, and to bring the beauty of real wood to your bedroom.
