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.

VERY VERY firm indeed! Only 3 stars because why is there no handle on one of the ends? This makes it MUCH harder to lift and rotate the mattress - REALLY, REALLY, REALLY ANNOYING and such a penny pinching thing on an extremely costly mattress. Would NOT recommend for this reason.

I absolutely love my new mattress. It is so deep it's like sleeping on a cloud. I thought my old mattress still had a bit of life left in it, until I saw my new Relyon Hayford Ortho 1500 mattress and my previous mattress side by side. It was definitely time for an upgrade. I decided to buy Relyon as my previous mattress had given me more than 20 years of amazing nights sleep. This Ortho mattress is is "solid" heavy and feels amazing on my back, hips, legs. This mattress is an investment in my sleep which I value. Would I purchase this mattress again from mattress on line again? Yes I would. However I suggest that mattress on line have a word with the delivery team. The stores offers "delivery to a room of your choice" The delivery team refused to deliver to the room of my choice. I (61f) struggled with my son to get the mattress to my bedroom. The delivery team should be ashamed of themselves, I am very disappointed with your service. I would not recommend them.

Even with super firm mattress and with turning every week, mattress developed pronounced dips on both sides where we sleep

This is a very firm mattress that also somehow manages to makes you feel you don't sleep on the floor. All in all very happy - but please bear in mind this review is just 5 weeks post purchase.
