Abstract
Abstract Bedding configurations are disclosed having supporting surfaces the firmness of which may be selectively adjustable by remote control means, providing for a supporting surface which may be quickly and easily adjusted by a user for maximum comfort. Various air chambers, cylinders, and tubes are disclosed for use in the central or "lumbar" portions of the mattresses of such bedding configurations, which may be selectively inflated or deflated in order to provide corresponding firmness levels. In a preferred embodiment a body support is comprised of an array of barrel-shaped coils that define elongate gaps at their top and bottom portions, with an elongate, inflatable tube positioned at least in the gaps defined in the top portion of the body support.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
100 words
An innerspring construction, comprising: a plurality of barrel-shaped pocketed coils comprising a first row and having substantially parallel longitudinal axes; a plurality of barrel-shaped pocketed coils comprising a second row and having substantially parallel longitudinal axes, said second row being adjacent to said first row such that the longitudinal axes of said second row pocketed coils are substantially parallel to said longitudinal axes of said first row pocketed coils and top and bottom elongate gaps are provided intermediate said rows at the tops and bottoms of said pocketed coils; and an inflatable elongate tube portion positioned within said top gap.
Claim 2
Dependent Claim
100 words

Claim 4
Dependent Claim
15 words
An innerspring construction as claimed in claim 2, further comprising means for inflating said tube.
Claim 5
Dependent Claim
15 words
An innerspring construction as claimed in claim 1, further comprising means for inflating said tube.
Claim 6
Dependent Claim
121 words
A mattress configuration comprising: a head region; a foot region; a center region itself comprising; a) a plurality of barrel-shaped pocketed coils comprising a first row and having substantially parallel longitudinal axes; b) a plurality of barrel-shaped pocketed coils comprising a second row and having substantially parallel longitudinal axes, said second row being adjacent to said first row such that the longitudinal axes of said second row pocketed coils are substantially parallel to said longitudinal axes of said first row pocketed coils and top and bottom elongate gaps are provided intermediate the rows at the tops and bottoms of the pocketed coils; and c) an inflatable elongate tube portion positioned within said top gap; and means for inflating said tube portion.
Claim 7
Dependent Claim
