Dune Fitted Sheet (Double) Review

What’s in the box

A double fitted sheet in 300 thread count cotton, with deep 14 cm sides and elastic all the way around the edge. It comes in a grey drawstring storage sack with the label sewn on, and Dune gives it a 12-month warranty. It’s made to fit Dune’s own 4WD self-inflating mats and comes in single, double and queen.

Quick Specs

On our rooftop tent mattress

Fitting it is easy, even in the tight space of a rooftop tent. It slid straight on and had plenty of give to wrap around the mattress without a fight.

The double fits the mattress perfectly, right into the corners, and the elastic all round holds it in place, so the sheet stays put when you roll over at night. The deep 14 cm sides are made for Dune’s thick self-inflating mats, so it has no trouble wrapping around a thinner tent mattress.

Sleeping on it

What you notice most is the feel. The cotton turns the mattress from a slightly synthetic surface into something soft that feels like your bed at home, and it felt cooler than the bare mattress straight away, which is what you want on warm nights in the tent. The 300TC cotton is dense and smooth, and the stitching around the edge is neat.

It also keeps the mattress cleaner. The dirt, sweat and oils of a trip end up on the sheet instead of the mattress, and a sheet is far easier to strip and wash than a tent mattress is to clean.

Washing and care

The care label is simple: a cold machine wash, separately, on a reduced spin, no soaking or bleach, no tumble dryer, and line dry in the shade. We wash ours when we get home from a trip. Cotton isn’t the fastest fabric to dry, so let it dry fully before you pack it away.

Packing it

The double weighs 500 g and packs into its own drawstring sack, about 24 × 33 × 6 cm, so it slides in with the bedding or the clothes bag without taking up much room. The sack is basic, but it keeps the sheet clean and folded until the next trip.

Single, Double or Queen?

The sheet comes in three sizes. All three are the same length and depth, so the only difference is the width: pick the one that matches your mat or mattress. The sizes and prices below are from the Anaconda listing when we checked in November 2026, so prices may have changed. The label on our double says 130 cm wide, so measure your mattress before you buy.

Conclusion: Dune Fitted Sheet

The Dune 4WD fitted sheet is a cheap, simple way to make a tent or 4WD bed feel more like home. The 300TC cotton is soft and cooler than a bare mattress, it keeps the mattress clean, and it weighs 500 g packed in its own sack. The double fits our rooftop tent mattress perfectly, there’s a single and a queen too, and it only comes in grey. For about $30, it’s one of the best small upgrades we’ve made to our sleeping setup.
