The Sleepeezee ActivFlex Response 3600 Pillow Top Mattress offers enhanced cooling and pressure sensitive features, along with sumptuous cushioning and innovative support.
Responsive layer
Featuring a layer of ActivFlex™. It's a profiled design allows more flexibility and helps improve airflow. It combines the benefits of pocket springs with foam to bring enhanced responsiveness. The ActivFlex™ layer adapts and flexes to your unique body shape and movements while you sleep, providing soothing pressure relief.
Refreshingly cool
The StayCool™ gel foam layer helps to regulate your temperature by drawing heat away from your body and promoting airflow. This helps keep your mattress cooler throughout the night and could be beneficial for those who tend to sleep hot.
Triple-layer spring system
Designed for optimal support and durability, this mattress features three layers of pocket springs. At its core 1200 traditional pocket springs provide a sturdy foundation of structure and support. Adapting to your weight and movements, these springs tailor strong support throughout the night.
This fully encapsulated spring unit delivers reliable edge-to-edge support maximising the usable sleep area and extending your mattress's lifespan.
Above this core layer, 1400 mini pocket springs enhance responsiveness, effortlessly adjusting to your body's movements and increasing comfort. Finally, a top layer of 1000 mini pocket springs is nestled within the pillowtop, adding a plush, cushioned feel for a soothing sleep experience.
Breathability
A microquilted cover promotes airflow and has moisture wicking properties that help keep your mattress surface fresh and dry. The addition of air vents along the border promote breathability, allowing more air to flow through the entire mattress.
Convenient care
There's no need to turn the mattress over - just rotate regularly to ensure longevity and continued comfort. Convenient flag-stitched side handles aid rotation of the mattress. A mattress cover made of 100% polyester is both durable and easy to clean. Comes with a 10 Year Guarantee.
Please note: pocket count is based on a King Size mattress.
This mattress comes with a 60-Night Comfort Trial - like all of our mattresses!
The trial lets you test your mattress for up to 60 nights. If it's not quite right for you, you can exchange it for a new one.
It can take some time to get used to a new mattress, which is why we ask you to sleep on your mattress for 30 nights. If you're not happy with the feel after 30 nights, simply contact our Customer Service Team, and we'll arrange a mattress exchange.
