Is medium a good mattress?
Yes, medium mattresses offer the perfect balance between support and softness.
They’re ideal if you like a bit of ‘sink-in’ comfort without too much give, making them great for side sleepers or those with a lighter to average build.
Why choose a medium mattress?
Medium mattresses give you plush comfort with just the right level of support. If you find firm mattresses too hard and soft ones too sink-in, a medium mattress is a great middle ground.
Try it risk-free with our 60-Night Comfort Trial.
