Premium cover that was ordered a bit too tight for my tub, resulting in some seam separation (photos). Partial restoration recently including removal, drying and waterproofing of styrofoam inserts, sewing of side seam separation, and closure of factory drain holes on underside (a major design flaw, IMO). Well kept and frequently treated with protectant. Mold free inside and out as it was used with saltwater chlorine sanitizer system - the trace level chlorine gas when covered kept everything virtually sterilized. Fits tub 73-75" x 78-80".
