Mah Jong modular sofa by Roche Bobois; each part (i.e. cushion, back) is about £600 (could be more depending on fabric). So, four pairs of two cushions + two backs (for two facing units) would be min £6,000 Could start with only one cushion.
PB Teen Furlicious Beanbag, Large, Ivory at Pottery Barn Teen - Bean... (£66) ❤ liked on Polyvore featuring home, furniture, chairs, accent chairs, bean bag, cream chair, pbteen, antique white chairs and circular chair
I've been desperate for a beanbag for a very long time now and after seeing this fluffy one on PBTeen, I'm dead set on it. Sadly, there's no such thing as PBTeen in Singapore, but that's what online shopping is for :)
