We will do one of three things:

Product Description
The Mammoth Performance Pocket 1600 mattress is the perfect blend of highly effective Medical grade Foam and a more traditional Pocket Spring unit. This combination of Pocket Springs and foam is an excellent way to ensure the support and comfort on offer a well balanced. This is a hybrid mattress in it's truest form.
The Performance Pocket 1600 mattress has a 7cm deep layer of foam on the surface, acting to provide a comfortable sleeping surface at all times. Furthermore, this layer is of the Mammoth specification, which means it boasts V-Max Cell Technology, allowing air to move freely through the mattress, cooling it as it moves. These cells also act like Pocket Springs, but with a softer, comfort-based approach.
The 1600 Pocket Spring system at the core of this Mammoth mattress act like pistons, moving up and down exactly as required according to the amount of weight applied. This means that the body will receive the correct level of support for a very small, precise area of the body. This happens instantly, enhancing comfort and encouraging good posture.
This mattress is also foam encapsulated, so all sides of the mattress are encased in a foam layer. This creates a stronger edge to the mattress, preventing any roll off and also increasing the lifespan of the mattress. The Performance Pocket 1600 is finished in a smart material, Tencel. This fabric is natural, and superb at controlling heat and moisture in the mattress. The cover is also removable and machine washable for added convenience.
This Mammoth mattress is Zoned, offering a higher level of support than other mattresses. the mattress is made to a slightly different, more supportive specification in the lumbar region, ensuring the hips and back remain perfectly well supported, and preventing aches and pains in the morning.
Mammoth mattress are fully endorsed by numerous sporting bodies and medical groups, and are scientifically proven to enable you to go to sleep quickly, and for the body to recover quicker too, hence the popularity of Mammoth mattresses among sportsmen and women.
We deliver this mattress with our 2-man service and deliver to the room of choice.
