Hot on the heels of today's Tron chair post is another type of unusual seating - albeit a little more portable than Dror Benshetrit's design.

Blow sofa is perfect for people who do a lot of moving or camping since its easy to transport when flat and simple to inflate.

Made from 100% recycled paper dunnage bags (which are water resistant) with a metal rack and rubber straps; and each section can be personalised with a pen too.

We think this is a great version of old school inflatable seat pads, and a darn sight more comfy too.
