3D mesh mattress underlay: reviews and experiences
All reviews from our shop, the good and the bad, plus the ratings on Amazon: what customers report about Matnext Airflow in the motorhome, roof tent, boat and bedroom.
3D mesh mattress underlay reviews: the essentials first
In short: Most reviews report that the mattress stays dry from below with the 3D mesh underlay: in the van, the roof tent, the caravan, on the boat and at home. Customers also praise how easy it is to cut to size and the service. The only criticism in our shop so far is a long delivery time. On matnext.de, our German shop, two reviews also say the underlay did not help against moisture, and in two others 20 mm was too high for the roof tent.
We sell the underlays ourselves. That is why this page shows every review from our shop, including the critical ones, and next to them the number of ratings on Amazon.
- Many report a dry mattress
- Easy to cut with scissors
- Roof tent: 10 mm when height is tight
- Room air too humid: also air and heat

All reviews from our shop
Newest first, with all stars.
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!

What customers praise
The mattress stays dry
This is the point most people mention when they write about the effect. A few voices from our shop:
- “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!” (Rosie, Matnext Airflow 10 mm, May 2026)
- “Excellent for boat beds. Stays dry even in humid conditions! Definitely worth the price for the quality you get.” (Sarah, Airflow BALANCE 15 mm, October 2024)
- “We use it in our roof tent. Perfect against mold!” (Ingo A., Matnext Airflow 10 mm, April 2021)
- “Installing the Matnext Airflow 20mm in our campervan has made a world of difference. The mattress stays dry and the added comfort is noticeable on every trip.” (Emily, Airflow PLUS 20 mm, August 2024)
- “Ideal for our caravan. No more mold! The material feels sturdy and is easy to cut to size.” (Daan, Airflow BALANCE 15 mm, February 2025)
Easy to cut to size
The underlay can be cut to size with scissors, including cut-outs:
- “Great for ther RV. Lightweight and easy to cut. Keeps moisture away efficiently.” (Charlotte, Airflow BALANCE 15 mm, November 2024)
- “The Matnext Airflow 10mm was exactly what we needed for our bed in the caravan. It's easy to cut to size and has significantly improved the air circulation. We now wake up without a clammy mattress, what a difference!” (Arjen, Matnext Airflow 10 mm, August 2023)
Recycled material and a little padding
- “High-quality material, love that it's made from recycled fabrics. Great for both home and travel use.” (David, Airflow BALANCE 15 mm, October 2024)
- “Keeps my bed dry and adds little padding. Worth every penny. I’m impressed by how durable it is.” (Oliver, Airflow BALANCE 15 mm, September 2024)
Important: the underlay belongs on a closed, level surface such as a board or the floor, not directly on the slats of a slatted base.
Service
- “Thank you to Michael and the Matnext team for being so responsive and helpful!” (Rosie, Matnext Airflow 10 mm, May 2026)
Criticism and bad experiences
This is part of it too. In our shop, one review with 3 stars criticises the delivery time (as of November 2026):
- Delivery time: “The Matnext Airflow 20mm is a really great product and has significantly improved the comfort in my camper. However, I'm only giving 3 stars because shipping took much longer than expected, which was disappointing. Overall, I'm happy with the product, but I hope the shipping service improves.” (Andrea, 3 stars, Airflow PLUS 20 mm, May 2024)
Three further reviews give 4 stars without naming a point of criticism. On matnext.de, our German shop, there are more critical reviews. We show them here translated, but do not count them:
- Did not help: two reviews of the Airflow PLUS 20 mm. “I am disappointed, the problem with the moisture persists.” (Sarah H., 2 stars, February 2025, review on matnext.de, translated from German) and “Unfortunately does not work at all in our motorhome. Mould still appears.” (Marie K., 1 star, October 2025, review on matnext.de, translated from German)
- Height in the roof tent: “A bit tight on height with 20 mm, though.” (Heinrich J., 4 stars, January 2020, review on matnext.de, translated from German). In another review on matnext.de, 20 mm was exchanged for 10 mm in the roof tent.
- Price and packaging: “A bit expensive but simply brilliant” (Hildegard Z., 5 stars, October 2021) and “Only the shipping packaging was a bit flimsy.” (Melanie W., 4 stars, December 2024), both reviews on matnext.de, translated from German.
Why an underlay alone is not always enough
We do not know why it did not work in those two cases. What is clear: a 3D mesh underlay creates an air space under the mattress so that the moisture from the night can escape sideways. It does not lower the humidity in the room or in the vehicle. If the air is permanently too humid, water still settles on cold surfaces, such as windows and outer walls.
The German consumer advice centre (Verbraucherzentrale) recommends 40 to 60 percent relative humidity for living spaces. If it is higher, regular airing and heating helps, and in a motorhome in winter also a dehumidifier. More on this in the guide moisture in the camper.
Which thickness? Experiences by place of use
Matnext Airflow comes in 10, 15 and 20 mm. This is how the 51 reviews in our shop are spread across the places of use (as of November 2026, reviews without a place are not listed):
| Place of use | What the reviews say | Thickness in the reviews |
|---|---|---|
| Van and motorhome | no more condensation under the mattress, more comfort | 16 reviews: 7 with 10 mm, 6 with 20 mm, 3 with 15 mm |
| Roof tent | mattress stays dry, no more condensation | 7 reviews: 4 with 20 mm, 3 with 10 mm |
| Caravan | no clammy mattress in the morning, easy to cut to size | 6 reviews: 4 with 10 mm, one each with 15 and 20 mm |
| Boat | air between mattress and bed base, stays dry even in humid conditions | 3 reviews: 2 with 15 mm, 1 with 10 mm |
| At home | breathable, fits under the mattress | 3 reviews, all with 15 mm |
In our shop, 20 mm also works in the roof tent. On matnext.de, however, two customers found 20 mm too high or tight there. Where every millimetre counts, Matnext Airflow with 10 mm is the safe choice. Airflow PLUS with 20 mm gives the largest air space and a little more height. In between is Airflow BALANCE with 15 mm, according to the product description made of 70 percent recycled material.
Where the reviews come from
- Our shop: reviews that customers have left in our shop, with all stars. We do not check whether a review comes from someone who bought the product. Reviews whose text appears more than once are neither shown nor counted. Many reviews were written in another language, in that case we show a translation and say so.
- matnext.de: quotes from reviews in our German shop, translated from German and marked as such. They are not counted in any figure on this page.
- Amazon: average and number of worldwide ratings on amazon.de, read by hand, with date. Here too we do not check whether the ratings come from people who bought the product.
Our recommendation
For a mattress on a board, the floor or in a motorhome we recommend Matnext Airflow PLUS with 20 mm: it gives the largest air space. If height is tight, Matnext Airflow BALANCE with 15 mm or Matnext Airflow with 10 mm fit. Our underlays come in standard sizes and as a custom size.
Frequently asked questions about the 3D mesh mattress underlay
What experiences are there with Matnext Airflow?
Many customers write that their mattress stays dry from below, in the van, roof tent, caravan, boat and at home. They also praise how easy it is to cut with scissors. The only criticism in our shop is a long delivery time. You will find every review from our shop at the top of this page.
Does a 3D mesh mattress underlay help against mould?
It prevents it: an air space forms under the mattress, the moisture from the night can escape and does not build up on the underside. It does not remove existing mould, and against permanently too humid room air only airing, heating or dehumidifying helps. More in the guide preventing mould on the mattress.
Which 3D mesh underlay for a roof tent?
In our shop, roof tent reviews mention both 10 and 20 mm. If the height is tight when closing the tent, Matnext Airflow with 10 mm is the safe choice, on matnext.de two customers found 20 mm too high or tight. More in the guide moisture in the roof tent.
Is there a 3D mesh underlay with 30 mm?
Our underlays come in 10, 15 and 20 mm. The Matnext Airflow Topper is 30 mm high and has a 20 mm 3D mesh inlay. However, it lies on top of the mattress, not underneath.
Is the underlay available in 140 x 200 or 140 x 240 cm?
Yes. Matnext Airflow comes in many standard sizes between 70 x 200 and 200 x 240 cm, including 140 x 200 and 140 x 240 cm. For other shapes, such as over-cab beds, berths or bench seats, there is the custom size.
Is a mattress underlay worth it?
Above all where the mattress lies on a closed surface, such as a board, the floor or in a vehicle. Otherwise the moisture from the night cannot escape downwards there. On a slatted base with air underneath, the mattress usually gets enough air without an underlay.
Try it yourself
Matnext Airflow comes in 10, 15 and 20 mm, in your width and length or as a custom size.
