My apartment back then was certainly tiny, but we were able to fit that behemoth sofa in there somehow. Yet now that I know that sleeper chairs exist, I don't think I'll ever put myself through that kind of struggle again.
Just as Erin at Unclutterer posted this awesome entry about sleeper chairs, I got a comment on a previous entry asking about them. yeyejoijoi said that they were "looking for a small, comfortable, makes-into-a-bed-but-not-a-futon alternative. Then it would be multipurpose and the guilt would be relieved. Right?" Right!
My suggestion to yeyejoijoi was this piece from JC Penny's home furnishings; I'd actually been considering it myself.
These babies are on sale right now; some models have been marked down to $499 from their original price of $1,399. (Yeah -- big difference!)
IKEA also has a few offerings for smaller-than-sofa sleepers. Their HAGALUND is a loveseat sleeper that has storage space under the seat, and the PS LÖVÅS is super-affordable with a base price of $209. They also have cute slipcovers to change up the look and make it seem a little less like a sleeper.
Over at Unclutterer, Erin covers many more cute and non-gigantic options. My favorite is the Vincent twin sleeper from CB2. It's a bit more costly, but looks sleek and modern.
