Ypsilon sofa is a fun way to add style to the chill-out area of your house. It is an entirely modular island sofa with square quilting - perfect on its own and sublime with other island units, whether they be square or rectangular. The two different backrest cushions can be placed to taste on the sofa and have a counterweight so they can be positioned in two different ways (sleep & talk). This sofa is a 24/7 affair.
