These days there are growing numbers of outdoor furniture with interesting design and a twist in its material. Like this Bubble Club collection for instance. Made of polyethylene (plastic), designer Phillipe Starck again successfully make his signature on this modern piece with a touch of fun and traditional lines.
The collection comprises of sofa, armchair and table, which can fit into a moderate-big size backyard perfectly, or even in the living room for indoor use.
I personally think that the sofa is the best piece since you can just put it in the terrace by itself and it'll look and function great without any other furnishing. As for the table, it would look awkward without some seating. And the armchair.. well, it does look cute by itself, yet it won't function as much because of its single seater.
Yet, if you have the space AND the budget, no harm in investing on the whole collection :)
