Mosticare Materasso, Envelope Mattress Mosquito Net
The mattress is the barrier, nothing hangs above.
- Factory-impregnated permethrin, bound into the fibre, never sprayed
- Three-year effective lifecycle under normal use
- Ships with recycled-cotton carry sachet and deployment card
A WHO-standard mattress mosquito net designed as an envelope that encases the mattress itself rather than hanging above the bed, a canopy-free solution for low-ceiling rooms, bunk beds, boat berths, and camper vans, and a good fit for homes right across Europe, southern, eastern, western, and northern. Polyester mesh at 156-count density, from 90 g. Three-year effective lifecycle.
Not every bed has a ceiling to hang a canopy from. A bunk bed sits directly under the bunk above. A cabin on a yacht has a headliner twelve centimetres above the pillow. A low-attic bedroom in a Provençal longère has exposed beams at sitting height. A fold-down bed in a camper van, a pull-out sofa, a child's mid-sleeper, a bunk in a mountain refuge, none of them can take a four-corner canopy or a single-point wedge. The Mosticare Materasso is built for exactly these beds: an envelope-style net that wraps the mattress itself, so the mattress becomes the barrier and nothing needs to hang above it. Two sizes, Materasso Uno for single mattresses and Materasso Due for double, share one engineering specification and one claim stack.
What these nets are, exactly
The Materasso Uno is an envelope net sized for a European single mattress at 220 × 110 cm, packed weight 90 g. The Materasso Due is sized for a European double mattress at 220 × 220 cm, packed weight 165 g. Both are knitted from durable 75-denier polyester at a 156-count density (25 holes per cm²), the same WHO-standard mesh used across the full Mosticare range.
The fibre is factory-impregnated with permethrin at 9 g/kg (0.9% w/w), a WHO-recommended pyrethroid bound into the yarn during manufacture rather than sprayed on. Both variants are WHO-standard as long-lasting insecticidal nets and authorized for European Union market release under the EU Biocidal Products Regulation (authorization EU 0026815-0000 2035). The treatment stays locked into the fibre, does not leach meaningfully onto skin, and does not release into the air of the room.
Critically, the Materasso is an envelope, the mattress slides inside like a duvet slides inside a cover, or a pillow into a pillowcase. It is not a fitted slip (no elastic corners) and not a flat drape (it does not simply lie on top). The encased mattress then goes onto the bed frame as normal, and the barrier is the mesh envelope itself, protecting the sleeper from beneath and from the sides.
Why a physical barrier is the right approach, especially when there's no ceiling
The traditional canopy assumption, "hang a net above the bed", breaks down the moment the bed is on a second tier, inside a cabin, in an attic, or in a van. The industry's answers to those scenarios have historically been worse, not better: plug-in diffusers pumping pyrethroid into a camper van's tiny air volume overnight, coils burning in a ship's cabin, aerosol sprays in a refuge bunkroom where ten people are trying to sleep.
The Materasso collapses that bad choice into a clean third answer, a physical barrier at the mattress surface, so the protection moves with the bed no matter where the bed is. The permethrin in the fibre reinforces the barrier at the point of contact, bound into the yarn at a deliberately minimal dose and never diffused through the room, so the chemistry stays on the outside of the envelope and the air stays as clean as the confined space will allow.
Who it's for
The Materasso is for anyone sleeping in a space where a canopy cannot be hung: bunk-bed users (bottom or top bunk, children's mid-sleepers, hostel dorms, university halls with bunks), caravan and camper-van travellers, boat owners and sailors sleeping in cabins or berths, low-ceiling attic or mezzanine sleepers, fold-out sofa users, and owners of beds where the frame will not accept a canopy or four-corner suspension.
Sold right across Europe, southern, eastern, western, and northern, wherever mosquitoes now reach, the Materasso is built around European mattress sizes. The Uno is sized for European single mattresses up to 220 × 110 cm; the Due for doubles up to 220 × 220 cm. Above that, European king beds, the Mosticare Cubo Tre canopy is the natural upgrade (ceiling permitting). For a bed that can take a canopy and whose user prefers the visual separation of one hanging above, choose Cubo Uno / Due / Tre or Rondo instead.
How to use it well
The Materasso installs in a couple of minutes per mattress and stays in place through the season.
- Remove the mattress from the bed frame and lay the envelope net flat alongside.
- Slide the mattress into the envelope opening, exactly as you would a pillow into a pillowcase or a duvet into a cover.
- Close the envelope at the opening and place the now-encased mattress back onto the bed frame.
- Make the bed normally, sheet, duvet, pillows all go on top of the encased mattress.
- Inspect the mesh visually at the start of each summer season; repair small damage with the Mosticare Net Repair Kit.
- Don't wash it, by design. In normal use the mesh doesn't get dirty, it just ages. Washing strips permethrin out of the fibre and into wastewater, which harms aquatic life and weakens the protection you bought. When the net reaches the end of its protective life, replace it rather than washing it.
- Expect a three-year effective protection lifecycle under normal use.

Before you decide.
How is the Materasso different from a fitted mattress protector?
Will it make the mattress hot or feel different to sleep on?
Does it work on a bunk bed where there is no headroom?
Will it fit my mattress?
Is it safe to sleep on night after night?
Mosticare exists to protect people from the world's deadliest animal without poisoning the room in which they sleep, including when that room is a cabin, a camper, a bunk, or an attic. The Materasso is a quiet, certified way to do that where a canopy can't be hung: the mattress becomes the barrier, and nothing hangs above.
