The Easy King (formerly called the Create-a-King) is a neat little bedroom problem solver that you can use to turn two twin beds into a king size bed. The Easy King straps around your two twin mattresses, holding them together tightly, so they can’t scoot apart. But what about the crack between the two mattresses? The Easy King has a sheep skin center piece that covers and masks the crack between the two mattresses. We have tried this in our store and it is also helpful to get a high quality mattress pad to go on top of the Easy King and mattresses to further cover up the crack between the two mattresses. You can use the Easy King to connect two twin beds or two twin extra long beds.
