A panel assembly wherein plurality of upper panels are connected by a plurality of elongated couplers. Each upper panel is made of an elastic material and curved convexly outward at both the side edges thereof and extend in the transverse direction of the panel assembly. Each coupler extends in the transverse direction of the panel assembly and has inner curved surfaces which have curves coincident with those of the upper panels and extend in the face of each other on the upper portion thereof so that a gap, into which two of the upper panels can be inserted, is defined between the inner curved surfaces. A support member having nearly semicircular curve coincident with the curve of the panel and a plurality of couplers is inserted into the gap, so that the support member is fixed to the panels.
