Whatever floats your boat, man. I have friends who prefer the opposite, they have two single beds pushed together, but a shared blanket. Whatever.

But the crazy thing is that every single goddamn store that sells bedding, will sell you solutions to your problem. It's not like you go to one store for single-person beds and their matching single-person bedding, and then a different store for double beds with matching double bedding. No, the same store that sells pillows and sheets and blankets sells them in different sizes and you can mix and match as you please.
