I would like to recommend the protective cover completely. We have a 2-seater garden swing, for several years, and as many Protective covers bought and tried out - of really expensive to inexpensive - and no good experiences with it, until now! This case I have "übern thumb" bought, that I was not sure if it fits dimensionally and also with the material indication I could not do anything. Only the review I've read here, has prompted me to cover the purchase. The shell came was well packed in a plastic bag with zipper (whether that is again used, I do not know) and absolutely suitable for shipping. The shell itself is made of a relatively heavy plastic material, well sewn and matches our garden swing, as prepared for it - perfect. Due to the heavy weight of the envelope, this need not be additionally secured, even with more vigorous wind the sleeve remains on the swing. But one has the possibility of additional safety: In the shell below Metalloesen are recessed and supplied with a cord that can be pulled through the eyelets, the envelope can be tied down. A sophisticated product, what I further recommend very much.
