ActivFlex™ Spring Foam – Sleepeezee’s own profiled gel technology sits at the heart of this mattress, delivering a unique combination of plush comfort and responsive support that adapts to your body rather than working against it.
Staycool™ Gel Technology – Designed to regulate your body temperature throughout the night, the Staycool gel layer responds instantly to your body shape, helping to prevent overheating and keeping you in a deeper, more comfortable sleep for longer.
Medium/Soft Comfort Rating – Perfect for those who love a softer, more enveloping feel, this mattress gently cushions pressure points including the shoulders, hips, and lower back, making it particularly well suited to side sleepers.
Generous 33cm Depth – At a substantial 33cm deep, the ActivFlex Response 3600 has a premium, luxurious feel from the moment you lie down, and pairs beautifully with any divan base or bed frame.
No-Turn Design – Maintenance couldn’t be simpler. The ActivFlex Response 3600 is a non-turn mattress, so there’s no heavy lifting involved, just an occasional rotate to keep it performing at its best.
Handmade in the UK – Every ActivFlex Response 3600 is crafted by hand at Sleepeezee’s factory in Kent, ensuring a level of quality and attention to detail that mass-produced mattresses simply can’t match.
10 Year Guarantee – Backed by a full decade of manufacturer confidence, this mattress is built to last. It’s a long-term investment in better sleep, supported by one of the UK’s most trusted bed makers.
Product Details
The Sleepeezee ActivFlex Response 3600 is a premium medium/soft mattress designed for sleepers who want the best of both worlds, a plush, body-hugging feel without sacrificing the support needed for a genuinely restful night. If you’ve previously owned a PocketGel Plus mattress, the ActivFlex Response 3600 is its next-generation successor, delivering all the same luxurious comfort with enhanced technology throughout.
The standout feature of this mattress is Sleepeezee’s own ActivFlex spring foam, a profiled gel layer engineered to strike the perfect balance between softness and support. It responds to your body shape as you move, gently cradling pressure points such as the shoulders, hips, and lower back, making it an excellent choice for side sleepers or anyone who prefers a more cushioned sleep surface.
Working alongside the ActivFlex spring foam is Sleepeezee’s Staycool gel technology, which provides pressure sensitive support that instantly adapts to your body while actively helping to regulate your temperature throughout the night. If you tend to sleep warm or find yourself waking up uncomfortable in the early hours, this is a particularly welcome feature that sets the ActivFlex 3600 apart from standard foam mattresses.
At 33cm deep, this is a generously proportioned mattress with a medium/soft comfort rating, making it well suited to those who enjoy a softer, more enveloping feel. It is a non-turn design, so all that’s needed is an occasional rotation to keep it in great shape, no heavy lifting or complicated maintenance routine required.
Like all Sleepeezee mattresses, the ActivFlex Response 3600 is handmade in the UK at their factory in Kent and comes with a 10 year guarantee, reflecting the high standards of craftsmanship that go into every mattress they produce. Available in single, small double, double, king, and super king sizes, it’s a versatile choice for any bedroom and a sound long-term investment in your sleep health.
