One reason I like the look is that it reminds me of one of my favorite rooms in design history, the family room of Swedish artists Carl and Karin Larsson, depicted in Carl's 1898 watercolor, "Lazy Corner":
The Larssons' home (you can read all about it here) was above all a family home (they had 8 kids). You can see from this painting that it was important to them that the home be livable and comfortable: instead of a formal portrait of an impeccable sitting room, Larsson includes the dog, the mussed-up rug, the scattered newspaper, the slippers — and the wrinkled, just-sat-on slipcover on the couch. Like most of the textiles in the home (the rag rugs, the curtains, the bedclothes, etc.), the slipcover was handmade by Karin. Its wrinkled appearance was another sign of a warm, idyllic family life.
Some of today's loose slipcovers also suggest a cozy, comfortable home life, while others exploit the sensuousness of drapery. The Italian company Busnelli (image 4) has even made their slipcover non-removable, button-tufting the front and letting the back hang loose, evoking the dress of Classical marble statues.
What do you think about loose slipcovers?
