This Twin size bunkie board / bed support eliminates the need for a link spring! It provides support so that you can use a regular mattress on a Twin size bed rather than having to use a specific day bed mattress or box spring. This lays below the mattress on the bed frame. The slats are 2 1/2″ wide and are 2 1/2″ apart from one another. The slats are held together with a forest green burlap 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. We also have a variety of color options & themes available in our other listings! Dimensions: 37″ – 41″ (depending on the size you choose) Wide x 72″ Long
