Natural rattan and cane is only suitable for indoor use

Natural rattan and cane conservatory furniture is not suitable for use outside either in summer or winter. It is purely indoor furniture; although it could be used outside on a dry day and stood on a hard surface. Standing the furniture on grass can cause the legs to swell and split owing to the natural moisture levels in the grass. The furniture must be brought indoors at night.
If you want the furniture for a garden room then you will have to consider the humidity levels from the plants as excessive moisture could cause the natural materials to warp and moulds to form.
The furniture needs to be kept dry and frost free in winter in order to prevent the natural fibres from breaking and splitting.
