The rectangle is 1800mm x 1400 and the triangle is 1400 x 1200 x 900 so yes pretty big - good to throw in the home theatre for movies when needed. - yes they are for indoor and outdoor - they are waterproof, fireproof and.... oilproof??
I got one of each so I got the triangle for DS's room in bright blue (figure I can squish the triangle shape in better) and then the large green rectangle - will probably live in the Rumpus as for the moment it will be DS's play room until DH converts it in to his games room... It will add some colour with lime green and plenty of space there.
I will also have to visit Ikea for this room too as I will need some nice storage shelving for all the toys!
