Abstract
Abstract A seat arrangement has a support surface for the buttocks, and a support or bearing surface for the knees and the shins, the two surfaces being connected to one another via a common framework. The framework has a base portion, which extends beyond the downwardly extending projections of the support and bearing surfaces. The base portion is a substantially continuous frame. The seat arrangement also has a base support consisting of two halves, each possessing an interior recess or sleeve for surrounding the respective metal tube of the other half of the base portion for fitting the two halves together.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
255 words
A seat arrangement comprising: a common frame including a horizontal base having a pair of spaced-apart ends with longitudinal side members extending therebetween, a first vertical support strut extending upwardly from a center of one end of the pair of spaced-apart ends and a second vertical support strut extending upwardly from the other end of said spaced-apart ends, said first vertical support strut being connected to an edge of a first support frame with the first support frame being a cantilever spaced above the base and extending inwardly from the first strut towards the second strut with a projection of the first support frame being within the confines of the base, said second vertical support strut being connected to an edge of a second support frame with the second support frame being a cantilever spaced above the base and extending inwardly from the second strut towards the first strut with a projection of the second support frame being within the confines of the base; a first unitary support surface for supporting the buttocks of a person seated on said seating arrangement, said first unitary support surface being mounted on said first support frame inward of the first vertical support strut; and a second unitary support surface for supporting the knees and shins of said person, said second unitary support surface being mounted on said second support frame inward of said second vertical support strut so that both the first unitary support surface and the second unitary support surface are within the confines of the base.
