Steady support for my cushioned arm chairs. Now firm and like new. No more sagging. My sofas are like new now. Very good product. Well designed. Will buy again

Helps a bit but not much. I wouldn’t buy more.

Good overall. Definitely improved the seat support of my oversized club chair. I believe this is a good solution to delay having to replace the chair in a couple of years or so. Happy with the results.

Very happy with this purchase. I have a full size couch with recliner chairs on either side. Instead of buying a couch sized support board, I purchased two chair sized boards. It works perfectly for the recliner chairs and makes them much more supportive. The center of couch doesn’t have a support board and that works for me as well don’t tend to use the center. The support board is very effective.

So far so good, only had a couple of days
