It is essential you can easily take cushion covers off and throw them in a machine wash without skrinkage or fading. Naturally, cushions get dirty with food, sweat and enviromental sources. All our covers have been cleverly designed with hidden, easy to access openings using YYK, non-corrosive, marine-grade zips and easily removed for machine washing. Importantly, also easy to put back on so they look as good as new.
