NM, PS, and RS patterns will have seams at the cushion break on the front seat, out-back, and in-back. The arm is bullnosed, so patterns will be centered on the out-arm, wrapping over the arm top horizontally and appearing upside down on the in-arm. The backs have a bullnose edge, so any pattern will be upside down on the backside and will not align with the seat cushion when turned. The extra pillows are 20" and non-welted. Pieces are held in place with non-skid legs. Please remember to remove plastic caps before placement.
