What will we do with your old bed/mattress?
We will do one of three things:
- A local charity may want it. We have given them many items in the last year
- We may recycle the mattress
- Some mattresses cannot be recycled, and so we use a local disposal service to take care of the goods.
Product Description
THIS ITEM IS NOW DISCONTINUED
Mammoth has built a range of mattresses that have been developed in conjunction with sporting bodies and medical professionals from around the World. Backed by professional sportsmen and women and used by Olympic Athletes and International football and rugby players alike, this range of mattresses boasts scientifically proven improvement to your sleep, and therefore a better rate of recovery for your body. The Mammoth Performance 240 mattress is a best selling part of this hugely popular Mammoth mattress collection.
The Performance 240 mattress is designed to offer a medium / soft feel and is aimed at those who want a luxurious yet supportive mattress.
Because of the unique and precisely engineered specification that Mammoth has pioneered, this mattress will offer the very best levels of support and comfort, night after night. Mammoth mattresses boast a clever network of V shape foam blocks, each working independently of one another to ensure accurate and uncompromised support, much like Pocket Springs, but without sound and with a much more gradual rate of progression. Mammoth began this technique with experiments and science, and the outcome offers accurate support, vastly superior to a normal solid block of foam.
This Performance 240 mattress is intended to be medium firmness. The feel of this mattress is luxuriously and 'cloud-like' but thanks to Mammoth's unique construction, the mattress still offers incredible support, which boosts recovery during the night, and ensures the body enjoys enhanced posture support.
This Mammoth mattress boasts 3 Zones, which all work to support the body in different ways. The lumbar region of the body is supported precisely as it needs to be, as the main area where body weight is applied to the mattress.
The cover of this mattress is finished in a luxury quilted cover, which can be removed and washed when required. This cover material is a Tencel fibre material, perfect for maintaining a comfortable heat and moisture level.
We deliver this mattress with our 2-man service and deliver to the room of choice.
