Sleep Super King Memory Foam Mattress

£ 299.99

Our best selling super king memory foam mattress, offering great value for money while providing ultimate comfort.

Featuring our luxury 50kg/m3 memory foam and our 36kg/m3 high density support layer CNC cut with our unique tear airflow system to ensure that you get a brilliant night’s sleep without overheating. The combination of temperature sensitive memory foam and a high density support layer means our  mattresses closely conform to your unique shape and helps cradle your body and avoid unnecessary pressure on your body and muscles. Resulting in a deeper more restful sleep.

Unlike a coil spring mattress, there are no pressure points in places like your shoulders, hips, and knees. Your back is better supported because the mattress conforms to your back and helps it hold its natural shape.

    I'm a big fan of this mattress, my old one was around 9 years old and was in serious need of replacement. My quality of sleep since owning this has improved dramatically. I can't believe I put up with a bad one for so long.
