poor quality materials used to construct this chair.I have had two of these chairs, one a replacement for the original,both with the same issues 1.the pressed metal support between the pedestal and the seat base is too soft and bends,leaving the chair lob sided 2. the cushioning material does not keep its shape,after only a few days use the seat pad material is wrinkled where the cushion has collapsed...looks good in the pictures but that's about it.
