The legs of the daybed are screwed onto metal plates.  The metal plates are secured to the wood frame by 1/2 inch wood screws (the plate is already attached to the frame-this is not part of the consumer assembling).  One of the daybed’s leg was wobbling due to the wood screws where not holding the plate to the wood frame.  This is either a defect in the wood where  the wood screws were located or the 1/2 inch wood screws cannot handle the stress of weight.  I bought this particular brand (more expensive) than another similar brand due to the product information indicated a 500 lbs weight limit, implying most likely sturdier than the other brand that had 250 lbs weight limit.

I did not want to deal with the hassles of returning this product.  I ended up removing the legs of the daybed and placing the daybed on a twin size metal frame.
