The enormous boiler suit doesn't look so bad, but things take a more sinister turn when two artists haul out a pair of plastic canisters ominously marked 'A' and 'B'. These chemicals make up the polyurethance mixture. I pour them into a bucked, along with a blue pigment, then jump on the fabric mould while the artists stir the goo.
Before I can say 'bottoms up' the mixture grows before my eyes. It's poured into the mold where it will expand up to 18 times its original volume. A warm, soothing sensation creeps up my legs, then the temperature suddenly increases. Help, my pants are on fire!
The artists rescue me. Phew! We wait 15 mnutes for the foam to cool and finally peel away the fabric to reveal a one-of-a-kind Rebecca's-bottom-shaped foam chair. It's pretty roomy. Damn – it even shows up the cellulite.
This interactive design experience hosted by designer Martijn Rigters is an opportunity to make a bespoke piece of futuristic furniture. Rigters will help you create a unique foam chair that follows the contours of your body. The event is part of a month-long programme curated by the House of Peroni. The doors open from 4.30pm and you can enjoy a beer and Italian food created by Michelin starred chefs on the terrace as well as exploring the new wave Italian art and design throughout the house. Admission is limited to over-18s. Visit the website to book your slot.
