Product Description

The MA51 has 16 horizontal bladder cells to give a nice, smooth alternating pressure. Because of it's well thought out design, the MA51 will not bottom out when the mattress air hose in attached to the compressor power unit.
The economical MA51 comes with a powerful air compressor which puts out up-to 10 liters per minute (LPM) of air. The compressor alternates the pressure of the mattress to prevent pressure sores and is quiet enough to not wake you up during the night.
