The Activsleep Ortho Extra Firm 3ft single mattress from Sealy

Do you wake up easily during the night due to a partner or pet moving?

Sealy’s PostureTech Zero Deflection (ZD) system combats both weight and movement to avoid motion disruption, allowing you to wake up feeling rested and refreshed for the day ahead.

Allergy sufferer? We have the perfect solution!

Purotex microcapsules release friendly bacteria into the fabric of the mattress to clean up allergens, reduce humidity and create the perfect healthy sleeping environment. Adaptive uses the body’s energy to accelerate moisture wicking, evaporation and cooling- the ideal solution for a cool, dry sleep.

Listed spring counts are based on a king size spring unit (measuring 5ft x 6ft 6in /150cm x 200cm). The number of springs will alter on a pro-rata basis dependent on mattress size and spring unit surface area.
