The first swing that we received did not appear to be defective, but the seam tore right away the first time someone sat in it.  The weight limit was not exceeded.  Wayfair sent us a replacement.  The replacement also tore within a short period of time.  Again, the weight limit of 250 lb. was not exceeded.  Wayfair gave us a refund.  I think Wayfair is great, but this product did not work out for us.
