For a top bunk or an occasional bed, the Bedmaster Ethan Mattress does its job. 16cm keeps it under the guard-rail limit on most bunks, and on a top bunk that comes before comfort. I wouldn't use it as a child's everyday bed in a single, though, because the core is an open coil.
Thin on purpose, and open coil inside
Bedmaster builds it on an open coil spring unit with white fibre fillings, a quilted stretch-knit cover and a wire edge border. It's 16cm deep, double-sided and rated soft to medium, and Bedmaster markets it for bunks, cabin beds and mid and high sleepers.
On a bunk, thin is right: a deeper mattress raises a sleeping child closer to the top of the guard rail. Keep anything extra off a top bunk mattress. The open coil is the compromise: linked springs share movement and dip where a child sleeps every night.
What owners say
Owners are content: comfortable, soft and, in one owner's words, "adequate for the cost". That's a fair description of a budget bunk mattress. One owner's note is the useful one: fine for children, while adults may need the next step up.
Use it here, not there
Buy it for a top bunk or a cabin bed that a child uses now and then, or for sleepovers. For a child's main bed with no depth limit, buy pocket springs, and make sure the mattress meets the frame all round, because a growing back gets the better support.
What to buy instead
If the bunk is your child's nightly bed, a pocket-sprung bunk mattress is the better buy; Jay-Be's Graffiti Art e-Pocket is one at 14cm. For a single bed, a deeper pocket-sprung mattress is the better buy.
