Targeted support
With a generous 1400 Mirapocket springs, this mattress provides pressure relief to key points such as the back, hips and joints. The individually-nested springs react independently to movement, preventing roll-together and partner disturbance during the night.

Hand-made finishes
Careful hand-tufting finishes the mattress and secures the fillings for longer use and better performance.

This mattress comes with a 60-Night Comfort Trial - like all of our mattresses!
The trial lets you test your mattress for up to 60 nights. If it's not quite right for you, you can exchange it for a new one.
It can take some time to get used to a new mattress, which is why we ask you to sleep on your mattress for 30 nights. If you're not happy with the feel after 30 nights, simply contact our Customer Service Team, and we'll arrange a mattress exchange.

I am pleased with the Mattress, as it is Very good quality at a Good competitive price. I would advise paying a little extra for the White Glove Service. This will save you unpacking it and getting it onto the bed. My fault, should have read the small print. Nevertheless I Highly recommend this Mattress
