Has anyone actually tried updating an old couch with a slipcover instead of replacing the whole thing? The sofa at home is still comfortable and structurally fine, but the upholstery has become worn, there are a few scratches from the cat, and the original color no longer looks very appealing. A new couch seems excessive when the furniture itself is still good, so a washable cover sounds like a more practical solution. The main concern is finding one that fits properly rather than looking like a loose blanket and that can handle everyday use.
I ended up trying Mamma Mia Covers https://mammamiacovers.com/collections/couch-covers and the result was much better than expected. The fabric stretches nicely and follows the shape of the sofa, so it looks more like fitted upholstery than a temporary cover. I especially liked that it covers the armrests as well as the seat and back, which is useful with a cat around. The material feels comfortable, and when the cover gets dirty, it can simply be removed and washed. It gave the old couch a completely different appearance without the expense and hassle of buying new furniture.
