I was very impressed by the service from Mattress Online, especially Chris in customer services and Craig the manager of the Doncaster shop. My online purchase wasn't supportive enough. I visited the Doncaster store and Craig was brilliant, advising on the type and firmness of mattress best for me and I selected the Wentworth Mercer. Chris at customer services arranged delivery of it the following day. Excellent service by Craig and Chris. Thank you Mattress Online

Awful mattress. Too soft for a med-firm mattress, didn't support - slept like the letter U & got back ache. Also the wool/cashmere/silk top is really warm so don't be tempted if menopausal! Needless to say returned this & we're wonderfully happy with Silentnight UltraGel 1400 Mirapocket Mattress which is firm but the gel top feels cushioned. We're both side sleepers, normal weight & sleeping like babies now with no backache!

Supportive and comfortable. I was worried if medium would be too soft and uncomfortable. This is perfect.

Very comfortable hut supportive. No sagging or dipping after a few months of purchase. Perfect for anyone whose not quite sure whether to opt for firm to medium mattress. I would rate it a medium mattress but with a very comfortable feel.
