I purchased a less expensive reclining leather/vinyl set back in 2010 from Baer’s Furniture. Instead of a sofa and loveseat I purchased 2 full size sofas so we could kind of rotate them periodically and not just have the two places we sit most often worn out. We are just now looking to replace them because of wear. We have kids and dogs so they get abused some, but they held up well considering the price and quality. They are manual recline also, not the electric. More on reddit.com

I wish I knew. I went through a Lazy Boy couch and loveseat in less than 10 years. Replaced with Ashley, probably 7 years old now. It seems better than the Lazy Boy. More on reddit.com

What I found is that your average 2-3k sofa uses a foam density between 1.6 - 1.8 that breaks down fairly quickly. When you get to the mid tier brands the density improves to 2.0 - 2.5, although some will still offer a 1.8 as an option. These mid tier foams will still break down (depending on use) but are not 10+ year foams. Fyi a higher density doesn't necessarily mean a firmer seat, for example a 2.0 can come in soft, medium, or firm. Next my research led me to the longest lasting cushion you can buy, the spring down cushion. It can also be referred to as spring foam, or spring fiber depending on the material used. It's essentially constructed like a mattress using coils (Marshall coils) to consistently keep the cushion shape. Unfortunately only the high end companies offer these cushions as options. Most of these manufacturers are located in North Carolina, Highland House, Wesley Hall, Sherrill, King Hickory, Taylor King, and Hickory White to name a few. Along with better cushions these companies offer better construction, such as stronger hardwoods (maple, mahogany, walnut, and oak etc...), eight way hand-tied suspension systems, and more quality fabric options. Another long lasting option would be latex cushions, but once again not cheap. More on reddit.com
