Extra firm

The Activsleep Ortho from Sealy has been rated to have extra firm tension, which is ideal for people that tend to have a larger stature or need more support. Achieved through the PostureTech Support System, the twice-tempered springs increase durability and stability. It also supports the areas of the body which are the most strained throughout the day, such as the back, hips, knees and neck.

Comfort foam

Comfort foam or 7 zone foam is similar to memory foam, and will mould to the contours and movements of your body whilst you sleep. Like the spring system, this layer will provide great support for the areas of the body that need it most. This foam provides an extra soft layer, meaning that you can still have extra firm support without sacrificing comfort.

Activsleep Ortho Extra Firm Support

Who is best suited for an extra firm mattress?

People best suited to an extra firm mattress are back sleepers and those of a heavier stature. For back sleepers, firmer mattresses help support your spine correctly by not letting it sink into the mattress, also evenly distributing your weight. If you're of a heavier weight, an extra firm mattress is more appropriate as the springs have a higher tension and won't be strained under your weight. If you were to sleep on a softer mattress, the springs would be overly strained and therefore couldn't support you properly. Overall, this would leave you waking up with pains in your neck and back.

What mattress is a front sleeper best suited to?

Front sleeping is something to be avoided due to the added pressure it puts on your neck and back. However if you can't stray too far from your favourite sleeping position then its best that you use a firmer, as opposed to extra firm, mattress as it will best support your spinal alignment.

What makes a good quality extra firm mattress?

Mainly a good quality extra firm mattress will have durable springs that won't lose their integrity over time. With Sealy's Activsleep Ortho, the springs are twice tempered to enhance this aspect of the mattress. Sealy also give a 5 year guarantee with this mattress, signalling it's a quality mattress.
