None! I dove way too far into couch shopping a year ish ago. I got a custom sectional from Dream Sofa. More expensive, but it will last and is exceptional quality. There are other companies that will offer similar quality furniture. Some of the things to note, Costco sofas will use tons of plywood in construction that will break down over time. Also, the cushion density is low, so the cushions will lose shape and comfort over time. The sofas that Costo offers simply won't last and won't hold up. I recommend reading through this website to learn more and get some ideas of sofa companies that will give you something that will last Answer from TeepingDad on reddit.com
