Density/Firmness Rating - What's Best For You?
Each type of mattress varies by comfort grade, from soft to firm. Our density ratings (provided by the manufacturer) are to be used as a guide. Every comfort grade has its advantages, and the right one for you depends on your personal preferences but also your favoured sleeping position.
The Roseland Sleep Onyx reflex ortho mattress is rated as Firm.

Gentle support system, conforming to the shape of your body. Great if you sleep on your side or front.
Provides essential support to maintain natural spinal alignment. Ideal for back or front sleepers.
Reflex Foam - Align Your Spine
Reflex foam is made up of tiny holes that slightly adapt to your body shape, but bounce back against you at the same time. Often found in orthopaedic mattresses, reflex foam can offer a firmer feel and provide good spinal alignment.
Reflex foam is very flexible and regains its original shape very quickly, hence the name 'reflex'. This type of foam is very versatile and can take various formations within a mattress.
