One great sleep. One giant leap.

How exactly do we test mattresses?

We're proud of Emma products (naturally). But we test all brands with the same methodology and scoring criteria. Fair is fair.








Ease of use


In other words, how comfy and supportive your mattress is. We measure it three different ways.

Point Elasticity

How well will your mattress isolate motion on a single side? If your sleeping partner tosses and turns on the bed a lot and you don't wake up, then you're on a winner.




Our favourite test. How firm and supportive will your mattress be in a few years? To find out fast, we run it through a heavy rolling mill to simulate 4-5 years of body movements. If it’s still in good shape after all that, we’re suitably impressed.


A well-crafted cover helps your mattress last longer. We measure shrinkage after washing it to the manufacturer's instructions.

Ease of use

Hopefully, you won't be hauling your mattress around too often. But we still want to test how easy it is to move compared to its weight and how helpful the handles are.
