Description
The onethird Ortho Mattress offers excellent value without compromising on quality and comfort. It features a medically proven castellated layer, a TrueGel naturally cooling pocket layer, 1000 pocket springs, and Komfi's unique Ecofoam.
Health-focused design
Komfi’s medically-proven castellated foam is the result of the GNG Groups 40 years’ experience producing mattresses for healthcare settings in the UK. The foam is shaped into grid-like sections creating individual zones that move independently. Promoting airflow, minimising motion transfer and distributing body weight more evenly.
TrueGel comfort
The OneThird Ortho Mattress comes with a specialised TrueGel layer. This layer offers exceptional temperature regulation properties. The gel works to draw excess heat away from your body. While also providing targeted pressure relief by adapting to your body’s contours. Your weight is more evenly distributed and pressure points are reduced, easing muscle strain and relaxing your body.
Pocket Springs
A layer of pocket springs deliver tailored support, adjusting to your body’s unique shape for optimal comfort. This design minimizes motion transfer and promotes healthy spinal alignment. Ensuring you enjoy a restful, rejuvenating night’s sleep.
Sustainable manufacture
Committed to keeping our planet green, Komfi uses sustainable Ecofoam for the climate conscious. This specially designed foam is not only durable and resilient, but is naturally dust mite resistant too. Manufactured by a carbon neutral company and 100% recyclable at end of use.
Strenuously tested
Komfi strenuously test their mattresses with advanced pressure-mapping software. They test all sorts of sleeping positions to ease pressure points for every type of sleeper. These tests demonstrate that TrueGel technology excels at relieving pressure. Delivering a sensation of weightlessness for both body and mind as you drift into restful sleep.
