Though this Urban Outfitters Rattan Pouf ($88) isn't a huge splurge, I think nearly 100 bucks (when you add shipping) is a lot to spend on a simple rattan cushion. This is especially true for me since I'd like to buy a few of them! It's such a great durable indoor/outdoor product that you can pull up as extra seating when you've got a full house. I do know of a more affordable alternative that's just as versatile and handsome, though. To see where you can get it, read more.
The Ikea Alseda Stool ($29.99) will save you 50 smackers on your spare seating. Although not as "poufy" as the Urban Outfitters pouf, it's just as comfortable (I can attest) and certainly good-looking. This alternative also stacks up well since it's more flat, which is ideal if you're buying more than one.
