, Description:TECHNICAL FIELD
[001] The embodiments herein generally relate to a mattress and more particularly, to an adjustable mattress and a method of providing the adjustable mattress.

BACKGROUND
[002] Adjustable beds may contain at least one adjustable section which allows a user to control the position of the same. The user may typically adjust the position of the adjustable section by using a position adjusting mechanism. However, such position adjusting mechanisms which are used for adjusting the position of mattress sections are positioned external to the mattress sections and are connected to the bed movable frames onto which the mattress sections are positioned thereon. To adjust the position of the mattress sections, the position adjusting mechanism moves the mattress sections through the bed movable frames. Conventional mattress is a single planar mattress and is not adjustable (flexible). Therefore, providing adjustable mattress is difficult and is one of the challenges faced by original equipment manufacturers (OEM’s).
[003] Therefore, there exists a need for an adjustable mattress and a method of providing the adjustable mattress, which obviates the aforementioned drawbacks.

[007] Another object of embodiments herein is to provide an adjustable mattress which includes linear actuators (position adjusting actuators) disposed inside the mattress.
[008] Another object of embodiments herein is to provide an adjustable mattress which can be positioned on a bed or a floor or a platform.
[009] Another object of embodiments herein is to provide an adjustable mattress which is user friendly.
[0010] Another object of embodiments herein is to provide an adjustable mattress which can be placed an existing bed of corresponding size.
