Cushioned heaven
Sink-in to the comforting embrace of cosy, breathable fibres. Two layers are formed from a blend of cotton and polyester fibres for cushioned comfort. Cotton fibres help to wick away moisture whilst the polyester fibres increases airflow to keep you feeling fresh.
Adding to the comfort are two layers of soft white fibres which enhance breathability further for a refreshing slumber night after night. These fibres are durable, ensuring you can enjoy their comfort for longer and help the mattress retain its shape.

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.
