To buy or not to buy, that is the question

I am coveting very much these chairs (scroll down to see more of the fabrics available). I think one of these would look perfect in the Old Shed. And there are some Cath Kidston ones available for just £99 + p&p. Now, admittedly, that's £99 I haven't got. But I expect I could scrape it together from somewhere. Though I'd really been wanting to save up for a sofa. Maybe this one. Or, in my wilder dreams, this one.

I'm not sure how comfortable the chairs look. But they're so pretty.

What would you do?

ETA: Okay, a bit more hunting round the internet and I've come up with this alternative. It claims to be available in over 2000 fabrics, but they don't have samples online. Looks cosy and is only 150cm wide. By comparison, the John Lewis Portia sofa is 136cm, and the pretty Delft one is 141cm. The IKEA sofa amamama suggested is 177cm which I think is going to be just too big for the space.
