They do well to relieve the pressure in key areas such as the hips and lumbar area.

Hybrid, memory foam, and pocket-sprung options provide a good balance between comfort and support.

Memory foam mattresses come in all shapes and sizes, with numerous layers making up their structure.

Hybrid mattresses offer the best of both worlds, as they have a layer of foam for comfort and a core of springs for additional support.

Memory foam is known to trap heat, so if you are a hot sleeper it’s important to look for design with enhanced breathability.

Emma rates the firmness of this mattress as 7.5 out of 10 on its firmness scale.

The Panda Hybrid Bamboo mattress is a little shallower than the 27-centimeter Simba Hybrid Pro and Nectar Premier Hybrid.

It has six layers of foam and 800 individual pocket springs to create a mattress that moves with your body and contours it gently.
