Question: Couch sits too low for these old knees so I'm looking to make my couch higher. Can I attach these to existing bun feet?
Document: Excellent look and raised our sofas a bit higher so not quite as low to the floor! An easy solution.
Our ikea couch was way too low and looked ridiculous next to our other (mostly antique) furniture. These legs raised it to the perfect height and gave it a classier look that is much more suited to our space. They seem well made and I have no complaints at all.
Good product for  the problem I wanted to solve about my sofa. My sofa is well balanced now and looking all good
These feet made my couches look so elegant. I was ready to buy new chairs but thought I'd give these a try and they were a definite upgrade. Highly recommend these.
These were absolutely a great purchase! I purchased a beautiful antique love seat for a small area, however it sat too low. After a Google search on sofa legs, these came up with high ratings, needless to say, all of the comments and ratings were very helpful in me making a purchase, awesome decision!!! !
Before I purchased these I drew them out on a piece of paper to scale and placed them next to my couch and decided they'd be perfect. I wasn't sure from the picture alone if they might be too thin, but they were not, they are good size and stable for 7-8' couches requiring only four legs.
Made my couch last a while longer. Worked great
My sons couch was in good shape it just needed new legs.These legs made all the difference.They were cheap and easy to install.
Okay, so they are just legs for your couch, but they look nice and are a solid piece of equipment. They have a plastic &#34;foot&#34; at the bottom that keeps them from scratching the wood floors when you move the couch but they grip the floor better than others. Mine leans against the wall but the couch would still slide when you sat down or adjusted yourself. It was annoying. This one slides easily when you want it to though.
received quickly and item is just as pictured and I am very happy with the purchase and service!
