A chair having reclining capabilities is provided for use with infirm or geriatric patients. The chair includes a fabric seat and back which is formed from woven elastomeric yarns which allow by directional strips. The woven fabric provides air circulation to the patient to help prevent skin ulcerations and other ailments produced by prolonged contact. The woven fabric also allows for quick draining and drying due to liquid contact. The seat and back in the preferred embodiment are formed from extruded aluminum members which engage the fabric in a taut condition i.e. by resilient lateral supports.

1. In an articulated chair having a back and seat each for pivotable movement, the improvement comprising: a back frame, said frame comprising a pair of opposing side members, said side members each defining an exterior edge groove, a fabric layer, said fabric layer comprising elastomeric yarns, said fabric layer extending between said opposing side members and disposed within said exterior edge grooves, a tension support, said tension support positioned between said opposing side members to maintain said fabric layer in a taut configuration. 2. The articulated chair of claim 1 wherein said back frame side members each define an interior edge groove, a lateral back support, said lateral back support extending between said side members and contained within said interior edge grooves. 3. The articulated chair of claim 1 wherein said back frame comprises a metal extrusion. 4. The articulated chair of claim 1 wherein said fabric layer comprises polyester monofilaments. 5. The articulated chair of claim 4 wherein said polyester monofilaments are biaxially positioned. 6. The articulated chair of claim 1 wherein said seat comprises a pair of opposing side members, each of said side members defining an exterior edge groove, a fabric layer, said fabric layer extending between said opposing side members disposed within said exterior edge grooves. 7. The articulated chair of claim 6 wherein each of said opposing seat side members defines an interior edge groove, a lateral seat support, said lateral seat support extending between said opposing side members disposed within said side interior edge grooves. 8. The articulated chair of claim 7 wherein said seat side members comprises extrusions. 9. The articulated chair of claim 8 wherein said extrusions comprise aluminum. 10. The articulated chair of claim 8 wherein said extrusions are oval-shaped in cross section. 11. The articulated chair of claim 1 further comprising a recliner mechanism, said recliner mechanism attached to said seat and to said back. 12. The articulated chair of claim 11 further comprising a pair of side frames, a cross brace, said side frames joined to said cross brace, and said recliner mechanism joined to said cross brace. 13. The articulated chair of claim 12 further comprising a pair of movable arms, said movable arms each attached to different ones of said side frames. 14. The articulated chair as claimed in claim 11 further comprises a foot rest, said foot rest joined to said recliner mechanism. 15. An articulated chair comprising: a back frame, a seat frame, a foot rest, a recliner mechanism, said back frame, seat frame and foot rest pivotally attached to said recliner mechanism, said back frame comprising a pair of opposing side members, each of said back side members defining an exterior edge groove and an interior edge groove, a tensioned back fabric, said back fabric comprising biaxially oriented elastomeric yarns, a u-shaped lateral back support, said back fabric extending between said opposing side members and positioned in said exterior edge grooves, and said lateral back support extending between said back side members for tensioning said elastomeric yarns. 16. The articulated chair of claim 15 wherein said seat frame comprises a pair of opposing side members, each of said seat side members defining an exterior edge groove and an interior edge groove, a seat fabric, said seat fabric comprising biaxially oriented elastomeric yarns, said seat fabric extending between said seat side members and positioned within said exterior edge grooves, a lateral seat support, said seat support extending between said seat side members for applying tension to said elastomeric seat fabric. 17.
