I've been spending a substantial amount of time trying to cruise the Internet for steals and deals, and my latest hunt uncovered these super-cute Polka-Dot [1] covers from Pottery Barn. With medium ($24.99) and large ($29.99) still available, if you've picked up a bed insert [2] in the past (or already own any cushion either 36-x-48 inches or 50-inch square), here's a great way to switch up the pattern this season. At these highly discounted prices, it's definitely cheaper than buying a whole new bed instead. Sweet dreams!
