Choose the size you need your slats to be at the top of this listing! This listing is for a brand new set of king size replacement bed slats. These slats are used to provide extra support to your box spring and mattress and your exisiting bed. The slats lay across the bed where the box spring would rest and the box spring and mattress are then placed on top of the bed slats. There are no braces or feet included with the slats to rest on the floor. The slats are held together with a white canvas roll. This makes it really easy to roll up and transport, and also helps to keep the slats in position. You can select the width sizing that you would need your bed slats to be. We recommend measuring your bed and rails prior to purchase to ensure that the correct size slats are purchased. Measure the width of the bed at the front of the bed, the middle and back of the bed and use the shortest measurement as your needed slat size. Leave a small amount of room for the slats to fit into the frame, about a 1/4″ inch of space. Dimensions: 70″ – 78″ (depending on the size you choose) Wide x 80″ Long
