Why shouldn’t I sleep on my mattress on the floor?

Why would I get damp and mold?

The flat surface underneath a memory foam mattress traps air from entering or escaping underneath the mattress. –

By using a memory foam mattress on a slatted or divan style bed base a good flow of air can circulate around the mattress and underneath.

By trapping this air, and moisture that gets trapped between the mattress and the floor will stay there – damp will spread and linger and eventually mold will start to grow.

Where does this moisture come from?

  1. There is always moisture in the air, this can’t be helped but by allowing air to move freely, this helps prevent mold from growing on surfaces.
  2. Damp can come up through the floor – not only in a room on a ground floor but in some rooms upstairs if you live in a very damp or old house.
  3. When you sleep in bed, you sweat – you can’t help this. A duvet helps to trap heat to keep you toasty but it also traps moisture. When this moisture can’t escape, it can travel down into the mattress.
