the most poorly engineered product I have ever purchased. It has eight bolts to attach the legs and supports to the base.- How hard could it be right? Well the first ones holes were so poorly aligned couldn't get it to work at all. Great customer service from Wayfair, they said sorry and promptly shipped me a new one at no charge. The second one was almost as bad. Followed the instructions precisely and could only get the legs and supports attached after re-drilling all the holes larger. No wonder they didn't want the first one returned! Not recommended, there has got to be better quality control
