Motion Isolation

Sealy's mattresses, particularly those with memory foam or hybrid designs, often feature good motion isolation. This means that movement on one side of the bed is less likely to be felt on the other side, which can be beneficial for couples.

Cooling Technology

Some Sealy mattresses come equipped with cooling technologies, such as gel-infused memory foam or breathable covers. This helps regulate temperature and prevents the mattress from becoming uncomfortably warm during the night.

Sealy set up the Orthopaedic Advisory Board in 2007. This group is made up of orthopaedic surgeons and clinicians.
