The answer depends on which type of wicker loveseat you have chosen to buy. Standard Wicker Loveseats don't need cushions since they come designed to make you feel comfortable with the base built with the finest fabrics, tufted to give you all-day rest and comfort.  As much as Wicker Loveseats have tufted cushions, adding extra cushions makes you feel even more comfortable. The only reason why people tend to add cushions is to brighten thicker Lovesaeats and add a more appealing taste to your decor, but in the end, even without them, Wicker Loveseats tend to work just fine.
