Maui Backrest Absolute genius All Maui Backrests are not permanently fixed to the sofas and chairsinstead they are cleverly weighted to hold them in place and allow the user to position them as and where they see fit for maximum comfort. Sunbrella Fabrics are quite simply the best on the market for outdoor use: They were first manufactured in the 1960s with the intention of creating a fabric that was far longer lasting than cotton and Sunbrella have always maintained the belief that any fabric should be both durable and beautiful at the same time. Its robust performance characteristics offer resistance to both sunlight and chemical degradation over time. Sunbrella fabrics are also very quick drying as is the foam used within them to offer all round comfort even after a quick rain shower. These fabrics are also very easy to maintain.
