Hi Denise, Many thanks for your feedback. I’m ever so sorry you experienced issues with your order. I can only apologise that you received the incorrect screws. If you contact us via phone or email, we will assist with any problems and resolve as quickly as possible. It is stated on our site that on our Bridge units the legs need to be attached to the base but if you ever have any product questions, we will be happy to advise. Best wishes, Poppy
