Silentnight Healthy Growth Eco Waterproof Bunk Mattress im Test

The Silentnight Healthy Growth Eco Waterproof Bunk Mattress is a double-sided, 15cm single for bunk beds, with a waterproof sleep surface on one face and a soft knitted surface on the other. It costs £209 in UK single (90x190cm) from Silentnight, and it rests on the same medium/firm Bonnell open-coil unit as the brand’s other bunk mattresses.

What the waterproof side is for

The NHS notes that many children under 5 wet the bed, that most grow out of it, and suggests waterproof covers on the mattress and duvet in the meantime. This mattress builds that cover in. An accident stays on the surface instead of soaking into the EcoComfort fibre filling, which is the part of a standard mattress that never fully recovers. On a top bunk that saves real effort: stripping and remaking a raised bed at night is awkward, and a surface that only needs wiping and a fresh sheet is quicker. When the dry nights are reliable, you turn it over to the soft side.

Fit on a bunk

At 15cm the mattress meets the usual limit on single bunks. BS EN 747-1 requires the top of the mattress to sit at least 16cm below the upper edge of the guard rail, so this one needs a rail that stands at least 31cm above the slats; your frame’s maximum-thickness mark confirms it. Because a waterproof bunk mattress is usually bought for a younger child, remember that NHS advice keeps children under six off the top bunk altogether, so the bottom bunk is often where this mattress starts its life.

Limits

Like the rest of the Healthy Growth bunk range it comes in UK single only, and the interconnected open coils are simpler than pocket springs. The waterproof face is also less soft than the knitted side, which is the reason to turn the mattress once it is no longer needed. Silentnight’s guarantee runs 5 years as standard and 15 years when registered within three months.
