We only use high quality cloth material for this product, and we run a number of tests to make sure that our cover fits well to the Pello type of chair covers. We also test for shrinkage due to washing to make sure the covers fit well even after washes. The package includes replacement sofa cover compatible to ikea chair slipcover only. This package doesn't include chair. Warning: the covers are design as replacement sofa cover compatible to Ikea Pello Chair Cover (or Pello Armchair Cover), not for Poang chair. Please do not buy this product for poang chair!
