Great!
I've been struggling to find the right mattress for me. I bought an Eve mattress for my teenage son who kept telling me how well he slept.
The mattress is firm but supports your body really well. I used to wake up aching in the hips and back. I've had the mattress for 2 months now and not had any problems since.
I particularly love that you can unzip the top cover of the mattress to pop it in the wash.
