The teak slats are framed with either stainless steel or black stainless steel. The cushions are given a sophisticated touch through the use of buttons and decorative stitching so they are not waterproof but the beauty is still undeniable. The cushions are available in either a weather durable Sunbrella fabric or in imitation leather with loose patches sewn together by hand and buttons added along the seams. The leather cushions are for indoor use only.
