Oversized king comforters typically have dimensions of 114 inches by 96 inches. This is in contrast to the dimensions of normal king comforters, which are 96 inches by 96 inches.
The advantage of oversized comforters is their larger width, as they are able to fully cover one's mattress and box spring. Some stores that carry oversized comforters are CuddleDown.com, Walmart, and Better Homes and Gardens. CuddleDown.com has an entire category on its website dedicated to oversized comforters, and it offers several different patterns with synthetic or genuine down filling. The prices in 2015 range from $71.00 to $469.00, so its stock is appropriate for most budgets.
