    Product Description

    The Sleepeezee 4500 Memory Ultimate mattress features an impressive system of 4,500 pocket springs, combining traditional pocketed springs with delicate mini-pocket springs. Each spring is housed in its own fabric pocket, allowing them to adjust independently to your body shape, distribute weight evenly, and completely eliminate partner disturbance or rolling together. This is a supportive mattress, yet not rated firm. The top layers are very comfortable and the springs are supportive, giving an overall medium-firm feel.

    Above the advanced spring core sits a deep layer of innovative graphite memory foam. Unlike standard foams, this specialised graphite-infused layer has a unique cell structure that allows air and moisture to pass through freely. This structural core is cushioned by durable, soft white fibre fillings, offering exceptional recovery and rebound. The entire mattress is built with a fully encapsulated side support system, creating a rigid foam perimeter frame around the edges. It is beautifully finished with a breathable, microquilted, soft-knit cover and integrated air vents.

    Enhanced posture and reduced pressure points
    Say goodbye to morning aches and pains with a sleep surface specifically engineered for deep, pressure-relieving comfort. The 4500 pocket springs provide focused support to your hips, shoulders and spine, promoting healthy spinal alignment while reducing pressure points that cause turning and tossing. These springs will target the areas that require the most support and will provide that support instantly, even as you move during your sleep. The end result is deep, uninterrupted sleep that aids recovery.

    Heat control with cutting-edge materials
    For those who suffer from overheating at night, the advanced graphite memory foam actively draws heat away from the surface and disperses it from your body, maintaining an optimal sleeping temperature. As well as this, the cover material is infused with Graphene, a microscopic material with incredible heat-dissipating ability. The fully encapsulated edge-to-edge support ensures you can use the complete mattress surface without any side sagging, effectively maximising your sleeping space so you can sleep right up to the edge without fear of rolling off. Additionally, the high-quality white fibre fillings make this mattress completely hypoallergenic, resisting dust mites, mould, and bacteria, which provides a clean and healthy sleep environment ideal for allergy or asthma sufferers. With its medium-firm comfort rating, it delivers the perfect balance of cosy cushioning and firm, supportive relief for all sleeping positions.

    Easy maintenance
    Investing in a premium bed shouldn't mean high-maintenance upkeep. This mattress features an easy-care, single-sided design, meaning it is non-turn and never needs to be flipped. To keep the fillings evenly distributed and extend your mattress's overall lifespan, simply rotate it head-to-toe (spin it around). The process is completely strain-free thanks to the durable, flag-stitched handles securely attached to the sides. With a luxurious total depth of 26cm, it easily fits standard premium bedding while offering a substantial, high-quality profile.

    High quality and great durability
    Sleepeezee has been creating exceptional beds and mattresses since 1924, refining traditional skills alongside current innovation in their factory in Kent, England.

    Features of the 4500 Memory Ultimate

    Deep, luxurious and practical.

    No Turning
    The  4500 Memory Ultimate mattress simply requires rotating (spinning around) once per season. There is no need to lift the mattress, and, as we place the mattress on your bed for you when we deliver, it will never need lifting again. This makes maintenance of the mattress practical throughout its long lifespan.

    Strong Edges
    Sleepeezee has wrapped a perimeter wall of support foam around this mattress, creating very, very strong edges. As such, you can sleep right up to the edge of the mattress without fear of rolling out, and the everyday practicality is improved as you can comfortably sit on the edge when required.

    Deep Comfort Layers
    The  4500 Memory Ultimate has deep layers of comfortable, sumptuous fillings at the top of this mattress, as well as a double-depth layer of graphite-infused memory foam. This foam is designed to draw away excess heat and moisture and works perfectly with the breathable fibre fillings above.
