Though I wasn't sure if this was a good idea when I first saw the Nicolas Cage Pillowcase for Home Decor, Sofa, Living Room, Bedroom Decor 18 x 18 inches White19 One Size on Amazon, what eventually sold me on it was its advertised features: anti-shrinkage fabric that can accommodate machine wash under 60°C temperature and fits various seats from sofas to chairs or inside cars - all of which have been great reliefs for my overly accommodating lifestyle.
It's made of plush fabric with full-length printing on both sides, giving out a nice aesthetic vibe in any kind of room (which is even better than expected). Despite not including a pillow core, the quality itself doesn't noticeably suffer as long as you know how to stuff appropriately into it.
Overall experience with the product has been alright but nothing particularly special besides its potential longevity - given how durable the material seems to be after multiple usages and washing cycles.
