What exactly is a mattress topper?

It’s an extra layer you put on top of any mattress, to boost its comfort without buying a new one; they’re easy to move too, so they’re also ideal for sofa beds, students or travelling.

But most mattress toppers are just foam or fluff.

Simba’s are different: we pack them with our ingenious Aerocoil® microsprings, for cooler, superior comfort.

Which mattress topper is right for you?

All Simba toppers feature a non-slip base plus 4 elastic corner straps to secure them. And you can move them easily too; just roll them up and off you go.
