1. A seat cushion comprising:
- a foam bun, including a central region bounded on two opposite sides by elongated trenches; and
disposed in each trench, an elongated touch fastener strip having an exposed surface that carries a plurality of fastener elements;
wherein at least a portion of one of the elongated trenches has a bottom surface that is inclined with respect to the central region, and wherein substantially the entire width of the touch fastener strip is disposed on the inclined bottom surface; and
wherein at least a portion of one of the bottom surfaces of the trenches is inclined at an angle selected to allow the fastener strip to extend around a sweeping curve having a radius of curvature of at least about 15 inches.

Abstract
Seat cushions are provided including a foam bun, including a first, generally planar central region and a second, generally non-planar region, the first and second regions being separated by an elongated trench, and, disposed in the trench, an elongated touch fastener strip having a first surface that is bonded to the bottom of the trench and a second surface that carries a plurality of fastener elements. The trench has at least a portion of its bottom surface that is inclined with respect to a plane that is generally parallel to the planar central region, allowing the touch fastener strip to be extended around a curve in the trench without buckling.
