Description Hi Ebay Customer! These King bed slats will provide the support you need for most specialty sleep beds and several other types of mattresses with 2" to 2 1/2" requirement for warranty. These also accommodate all regular mattress sets providing firmness. Our wood is 100 percent renewable.and made here in the USA! ( see below ) They will provide a firm foundation with the slat boards approximately 2" or less apart. We make these to help support back issues where firmness is priority and sleep is essential. If your mattress "dips" or "sags" these can be used between box and mattress or under the box directly on the bedframe. Very good support is gained when used directly under top mattress stopping "sags" going down to box spring. We have sold 100's of these slats over the years and they have been well received and have worked for many customers!They lay directly on your bed frame and are held together with a strapping material to keep the slats in position. Please measure the width of your bed prior to purchasing your slats. Allow 1/4" play on either side of the bed frame when measuring. If you are buying these slats to go in between mattress and box spring then just measure across the mattress and purchase that width. If you don't see the size you need for your bed, please contact us and we will be happy to see if we can meet your specific request.
