The Sleepeezee ActivFlex Response 3600 Memory Mattress, paired with the Premium Divan Bed, offers unparalleled full-body cushioning and innovative support. Designed with advanced spring and foam technologies, this pairing delivers optimal posture control, cooling comfort, and clever under-bed storage options to complement your home.
Innovative support for posture control
The mattress features a core combination of full-size pocket springs and mini comfort springs that adapt to your body, providing targeted support and essential posture control with a balanced medium feel. An additional innovative ActivFlex™ spring foam layer enhances this support by combining the precision of springs with the contouring properties of foam, offering relief at every pressure point. The sumptuous pillow top layer houses an extra 1000 mini comfort springs for closer, tailored support, ensuring a soft yet supportive sleep surface. Paired with the Premium Divan Bed’s solid platform base, this set-up guarantees long-lasting comfort and stability.
Cooling comfort and breathable design
Two layers of Staycool™ gel actively draw heat away from your body, providing consistent cooling comfort throughout the night. This innovative material, combined with the mattress’s breathable pillow top layer, ensures a refreshing and temperature-regulated sleep surface. Together with the Premium Divan Bed’s airflow-enhancing design, this pairing promotes a cool, restful sleeping environment.
Sumptuous cushioning and practical elegance
Soft polyester comfort layers add luxurious full-body cushioning, delivering a sink-in feeling your body will thank you for after a long day. Finished with a luxuriously soft-knitted cover, this innovative Sleepeezee mattress offers a sumptuous touch of comfort. The Premium Divan Bed complements these indulgent features with customisable upholstery and practical storage options, such as drawers or an ottoman base, blending elegance with functionality.
While this divan does not come with one, it is perfectly designed to fit all of our headboards. Whether you prefer an elegant, buttoned design, or a simple, contemporary aesthetic, we'll have the ideal headboard to suit your style. You can also customise any of our headboards to match your chosen divan upholstery, creating the perfect divan set.
