These legs are great for any furniture including sofas chairs settee's beds footstools cabinets tables bookcases draws Furniture legs come with different fittings. Some have bolts which can come in 3 sizes M8 8mm M10 10mm & M6 6mm and others are self-fixing pre-drilled which fit to your furniture with 6mm wood screws. You will need to know the fittings you require. We can usually cater for most fittings depending on the footleg you choose. To ensure you order the correct bolt size you will need to check the bolt size on your existing legs. You are unable to do this with a tape measure as this will not accurately allow for the thread. The only way to be sure is to try a nut on the existing legs. If you try an 8mm nut and it fits you know its M8 if it’s too small you require M10 and too big you require M6. If you need any advice or help with which fittings to order please send us a message. We can usually suggest a type of fitting that will work for your requirements.
