The Comfort Plus range provides the most effective system for fine tuning the level of comfort available in any air mattress today. If you are on eneven or bumpy terrain, the you can inflate the bottom layer of the mattress very firm at higher pressure as a barrier. You can then adjust the upper layer, using the fine tune valve, to a lower pressure to feel softer and more comfortable. The Dual layer design also ensure a level of built in redundancy. If you do end up with a puncture in one layer of the mattress, then you can still get through the night with the other layer of the mattress intact.
