Memory foam 

Using technology developed by NASA for the space programme, memory foam mattresses are a modern marvel. The dense foam provides outstanding support and cushioning by moulding into the shape of your body. This eliminates pressure points but gives you a softer feel. Perfect for side and back sleepers. 

Pocketed spring mattresses 

Pocket spring mattresses are made up of a matrix of individual springs sitting in their own cloth pockets. This allows the springs to work independently to adjust to your body, minimising movement transference. They are perfect for couples, even if one tends to wriggle a bit during the night.

Traditional open spring mattresses

These use a traditional open-spring core surrounded by comfort layers. They’re a great budget option and ideal for use as a spare room mattress. They do need to be maintained a little more often, with regular flipping and turning to avoid lumps, dips and bumps from forming.  

Hybrid mattresses

These combine a pocketed spring core with multiple comfort layers finishing with a memory foam layer for that ‘sink-into-bed’ feeling at the end of the day. They range in price from budget-friendly to top-end, and are easy to maintain.

Medium firm Orthopaedic mattresses are designed specifically to help soothe back and joint pain, while latex models add a touch of luxury and elegance. They’re also great for managing allergies.

Is medium a good mattress?

Medium mattresses are suitable for almost anyone, providing an excellent balance of both comfort and support. Medium mattresses give you that soft, 'sinking into a cloud' feeling that you want at the end of a hard day, but with no compromise on support. They're particularly suitable for side sleepers, and choosing a memory foam mattress with a medium firmness rating means that you'll be cushioned and supported along the length of your body, eliminating pressure points and providing you with a great night's sleep. Medium firmness sprung mattresses ensure you get all the comfort you need, while at the same time eliminating any movement transference so you don't disturb your partner if you wriggle around at night. Medium mattresses are also suitable for those who prefer sleeping on their backs, although front sleepers may prefer something a little firmer to give them the support they need. 

Which is better, a medium mattress or a medium firm mattress?

There isn’t a huge amount of difference between the two, but you will notice that a medium-firm mattress has a firmer feel when you press down, and springs back more quickly than a medium option. Studies have suggested that a medium or medium-firm mattress can actually be better for those with back problems than a extra firm option, as the cushioning effect provides a greater degree of comfort and support. A medium mattress is better for back sleepers, while a medium-firm mattress provides additional support for those who prefer to sleep on their front.
