The Westminster Cantilever Parasols are truly great examples of modern cantilever parasols. Both are manufactured using high performance aluminium, hard wearing 300 gram Polyester fabric canopy, including base st&, all weather night bag & feature smooth & easy to operate opening & closing mechanisms. Mercury parasol bases should be filled with water or sand & have adjustable wheels for ease of movement. If required the Mercury Parasol can be fixed directly to the ground without the presence of the supporting base st&, in the case however the swivel option will not be usable. Parasol fabric can develop mould in excessively damp conditions & stains will appear if left under trees. Black parasol fabric can be more vulnerable to fading than the Natural colour & we recommend use of the all weather cover when parasol is not in use.
