Our couch used to be brown, but we recently ordered a replacement slipcover from Bemz. Bemz makes slipcovers for IKEA furniture in cool colors and patterns not available from IKEA. The guality is great (this green fabric is a cotton/linen blend) and the fit is perfect. Looks even cuter in person.
We removed the uncomfortable bolsters on our couch and replaced them with a row of fun handmade pillows. From L to R: Decaf Plush, Donna Wilson, Cathy of California (she doesn't sell these though), My Imaginary Boyfriend, BennyandHeidi, Decaf Plush.
