Experience the perfect balance of support and luxury with the Sleepeezee Cumulus 4000 Mattress. Designed with innovative features to ensure optimum comfort throughout the night, this high-quality mattress offers a sumptuous sleeping experience that adapts to your body’s every move. From its advanced spring system to temperature-regulating materials, every aspect is crafted to help you drift off into a deep, restorative sleep.

At the heart of this mattress is an advanced pocket spring system, engineered to deliver tailored support and exceptional bounce. The 4000 individual pocket springs move independently, providing optimal support and minimising motion transfer, making it ideal for couples and restless sleepers alike. The addition of graphite-infused memory foam works naturally to regulate temperature, ensuring you remain cool in the summer and warm during the winter months.

This mattress is finished with a plush, soft-knit quilted cover, creating a smooth, indulgent surface that enhances the overall comfort and elevates your bedtime routine. With medium firmness, it's perfectly suited for those who change sleeping positions, making it a versatile option for many sleepers. Easy to care for with a non-turn design, it simply requires regular rotation to maintain its shape and longevity.

  • 4000 individually responsive pocket springs for superior support
  • Graphite-infused memory foam for heat regulation and tailored comfort
  • Eco Comfort and Support Layer crafted from recycled materials

Rated by thousands of happy customers

We're proud to be rated 5 stars by thousands of customers. See what our customers are saying about us and leave us a review over on our reviews page.

From order to delivery, everything was seamless. I received clear updates throughout, and the delivery team assembled the furniture and took all packaging away. I've trusted Fishpools for over 50 years - always reliable. One very happy customer!
It’s rare these days, but Fishpools always does exactly what they promise - on time, every time. The quality is excellent, and spending a little more is worth it for the peace of mind you get in return.
Our 2-hour delivery slot was confirmed the day before, with a call 30 minutes prior. The fitters were friendly, professional, and careful - even protecting our hall floor. They checked I was happy before leaving and thanked me for the tea! Highly recommend Fishpools.
