Manufactured in the United Kingdom and approved by the National Bed Federation, the Sleepeezee Jessica Plush mattress is designed to adjust to all body shapes and ensure a good night�s sleep. Packed with individually pocketed springs, there�s more than enough support to spare and the levels of comfort are enhanced by Dreamzone body-contouring foam. If you�re a hot sleeper, the materials in this mattress help to transfer and regulate body heat.The Sleepeezee Jessica Plush mattress is designed to provide support and comfort for those who want to take their sleeping experience to the next level. Platinum breathable fibres ensure that heat is transferred away from the body during warmer weather and kept close during the colder months. Layers of memory foam and StayCool Gel help to reinforce the perfect sleep temperature and give an additional layer of luxury. At 16.5 inches, the mattress is substantially thick enough to accommodate sleepers of different weights but without giving way to that �rising and sinking� syndrome or unwanted roll-together. A great choice for those who like to sleep on their sides or back.Dreamzone foam is the perfect alignment of foam and springs to provide the comfort and support required for a good night�s sleep. 1800 individually pocketed springs provide tailored support, while a layer of body-contouring foam provides unparalleled snuggle-ability. Dreamzone was developed in Scandinavia to provide a resilient layer that is both lightweight and durable yet offers all the luxurious feel you�d associate with a high-end mattress.The materials used in the Sleepeezee Jessica Plush mattress are anti-microbial and resistant to dust mites, making this advanced mattress ideal for those with sensitivities to allergens and with allergen-responsive breathing difficulties. The fabrics are also resistant to the growth of moulds and mildew, for extra peace of mind. To ensure the mattress adapts to its surroundings, leave it to breathe for 48 hours before use. Superior wicking technology also ensures that the mattress is resistant to the damaging effects of the moisture found in breath and sweat.A white fibre support layer gives additional support to the layer of individually pocketed springs. White fibre is a calculated mix of synthetic and natural fibres, designed to enhance firmness and breathability. In addition to relieving the weight from pressure points, such as the shoulders, hips, and elbows, the mattress is long-lasting and comes with excellent heat-transfer rates.
