The bed rug is a one-inch mat made of coconut fiber (coir) with natural latex. The bed rug is porous and allows air to circulate between the bottom of a mattress and a platform bed's surface. It is strongly recommended for breathability under any foam mattress on a solid-platform bed. Where inadequate air circulation is a concern, a bed rug may be advisable on a slatted platform.
We recommend adding two bed rugs under a mattress in any highly humid environment for better air circulation.
Note: King bed rugs are two 38" x 80" pieces. Queens are two 30" x 80" pieces. (California King is not available.)
