For specialist support, the Spring King® Ruby Ortho Extra Firm Mattress is one of the firmest sleep surfaces you can find. For those of a particularly heavy build, those who have been recommended an extra firm mattress by a medical professional, or anyone who simply feels they need specialised help with back pain, this orthopaedic mattress can help to align your spine for a more comfortable sleeping position.

Consistently firm support

A traditional open coil spring unit features one continuous high tensile spring formed into a lattice shape. This innovative shape allows for a firmer, more consistent level of support, while a deep, firm filling of breathable white fibres ensures targeted pressure relief exactly where you need it. This expert level of tension relief can help you enjoy a more rejuvenating, refreshing night's sleep, with the enhanced air circulation within the mattress preventing overheating and encouraging a fresher sleeping environment.

Double-sided for even wear

Luxuriously hand-tufted to keep all fillings in place, the Spring King® Ruby Ortho Extra Firm Mattress is finished with a soft damask cover for a final touch of luxury. Double-sided, this mattress features robust turning handles to help you flip it each season, ensuring even distribution of fillings.
