Comfort is very subjective. There are no universal standards of firmness in common usage in the UK. Because of this we don't give our beds a firmness rating like some manufacturers. Your main aim is to achieve good "posture" in bed. Too soft and your body will slouch - often leading to back pain - and too firm and you will cause discomfort at pressure points such as your hips and shoulder. Ideally the mattress should mould to the shape of your body while remaining supportive. When you lie on your side your spine should be horizontal and you should be able to turn easily.
The term 'orthopaedic' generally just means an extra firm bed; it is not based on any medical or other common standard, nor does it mean the bed has been professionally assessed or recommended. It is a term loosely used by manufacturers to refer to extra firm models in their range. Firmness is not determined by price, although comfort, luxury and durability and added features such as adjustability come with higher price tags.
Our Ortho products include the Pistachio, Timara, Kassia and Marie.
Most retailers will not exchange a bed if it proves not to be comfortable, hence the reason why we encourage consumers to try the beds they like before making a purchase.
