The material that goes under the mattress is called HyVent. It is a firm material that resembles many layers of nylon mesh. Highly recommended for use on any platform bed in a poorly insulated area. Otherwise, moisture from your bodies and breathing will penetrate the mattress and condense under it, resulting in mold growth.
It is called Hypervent and it is pricy. I purchased a product few years back for a previous TC called Dry mesh that worked good but forgot to remove it when TC was sold. It was much cheaper than Hypervent. Cannot find a U.S. distributor now. I use blue or pink foam board that's works good too for around 10.00 bucks at Lowes.
