Abstract
A mattress having variable height and hardness is disclosed. The mattress comprises a base layer held by a mattress cover using an extendable attachment system. The mattress further comprises one or more top layers made of resilient material which are stacked on top of the base layer. Only friction between the material of the top layers limit the lateral or longitudinal movements of a layer with regard to another layer.
Claims21
1) A mattress with adjustable height and hardness, the mattress comprising:
- a base layer comprising a top surface, a bottom surface and a plurality of side surfaces;
- at least an upper layer comprising a top surface, a bottom surface and a plurality of side surfaces, the upper layer being made of resilient material and being adapted to stack over the base layer;
- a flexible cover adapted to cover the top surface of the topmost upper layer and to cover at least partially the side surfaces of the upper layers;
- a plurality of attachment mechanisms having a length adapted to vary according to the height of the mattress, each attachment mechanism comprising:
- a first member attached to the flexible cover;
- a second member secured to the base layer;
- wherein the first member and the second member are adapted to detachably mate to one another to solidly maintain the flexible cover to the base layer.
12) A method for building a height and/or firmness adjustable mattress, the method comprising:
- providing a base layer adapted to receive a predetermined load;
- stacking one or more resilient upper layers on top of the base layer based on predetermined desired characteristics;
- wrapping a top surface and at least partially covering side surfaces of the topmost upper layer with a flexible cover;
- adjusting length of each of a plurality of attachment mechanisms according to the height of the stacked base and upper layers, each of the attachment mechanisms being mounted to the base layer and to the flexible cover;
- securing, for each attachment system, the first attachment member to the second attachment member;
- and
- tightening each of the attachment mechanisms to limit movement of the base and upper layers.
17) A method for adjusting height and/or firmness of a mattress, the method comprising:
- detaching one or more attachment systems holding a cover to a base layer of the mattress;
- removing a cover wrapped over a top surface of the topmost of the upper layers of the mattress;
- replacing one or more upper layers with one or more replacement upper layers;
- and
- adapting length of the attachment systems to compensate for the difference of height after replacement of the one or more upper layers.
