How it works
Everyone gives off moisture while sleeping. It sinks through the mattress and condenses at the coldest point: the underside, where it rests on a solid base. The 3D mesh lifts the mattress onto an open air gap, so the moisture escapes before it can settle.
On a bed box, the floor or a boat berth the moisture has nowhere to go. It collects under the mattress, the first mildew stains follow.
The 3D mesh
Upright polyester threads hold the air gap open under several hundred kilos and spring back into shape.

Areas of use

On the road
Stops trapped moisture between the bed box and the mattress, without daily airing.
In box spring beds, on closed slatted frames or on the floor against a musty smell.
The 10 mm version still lets a hard shell tent close safely.
Keeps the mattress in the berth dry and helps prevent mildew stains.
Customer reviews
“With the underlay there really is no more moisture under the mattress. We use 2 of them in the caravan.”

“I ordered Matnext Airflow 3D Mesh 10mm for under our mattresses on a sailboat a month ago (I have also used them on a previous boat). They have been amazing at keeping airflow between the mattress and bed base, as well as preventing moisture from being trapped between the two. I would 100% recommend these to anyone! Thank you to Michael and the Matnext team for being so responsive and helpful!”
“Great for ther RV. Lightweight and easy to cut. Keeps moisture away efficiently.”
“Excellent for boat beds. Stays dry even in humid conditions! Definitely worth the price for the quality you get.”
FAQ
Yes. Curves or corner cuts are easy to do yourself with a good pair of household or tailor’s scissors.
No. The honeycomb structure keeps its stability without sewing. Tip: cut it where you can vacuum afterwards, because a few loose threads come off at the edge.
Yes. The stain resistant polyester mesh can be washed in the machine at up to 40 degrees. It does not absorb odours or moisture and dries very quickly.
Both reduce condensation and help prevent mould. For small areas without a gain in comfort, the 10 mm version is enough. For noticeably softer lying and wide areas, choose the 20 mm PLUS.
Yes. For hard shell roof tents we recommend the thinner 10 mm version, because the 20 mm version may not let the tent close.
