Absolutely love these slipcovers!  They fit my box soft and loveseat perfectly.  The cotton fabric is sturdy and the slipcovers are well made.   Getting the wrinkles out will take a little effort.  What worked for me was thoroughly spraying them with water before putting them in the dryer with a few fabric softener sheets.  Ironing the front panels manually will give you that wrinkle free look.  The effort is worth it.
