TigeJoy Heavy Duty Sofa Cushion Support Board for Sagging Couches, Thick Solid Wood Boards Add Strong Seat Supports, 20.5''W x 81" L for 4 Seats Sofa, Replacement Stuffing Under Couches Sofa Saver

Just to be clear, I think the wood, while "solid" is manufactured wood, but it seems very sturdy, and what it does to my 16 year old couch is amazing. No more sitting down and disappearing. I highly recommend!

I have a mattress that sags a bit on one side (after it took a tumble on the highway during a move), but it was still new enough that I didn’t want to replace it unless I had to. Plus, I don’t sleep on that side, anyway, lol. So, I bought this as a temporary alternative. It works great. The mattress is much firmer and more comfortable on that side now. They also work great for their intended purpose, which is saggy seats.

Buy it if you have an old worn out couch or even if your cushions are shot. I went both routes and purchased new filler for the cushions because we cant afford a new couch right now, and i also ordered this thing. I had this under the cushions while we were waiting for the new stuffing to arrive and i was rrally surprised at how well it worked...The only knock i have on it is the width dowsnt quite go under yhe entire cushion so my only gripe is i wish they made a wider one, but the lentgh itself worked perfectly.

My sofa had a slight dip in one section only. It’s a sectional and only about two years old. Only one seat went too far down when you sit on it. These savers gave new life to it. The sofa feels brand new again. I can sleep on it and wake up with a backache from the drooping in that one cushion. This supports the seat all the way across. Glad I got these. I got two for my sectional.

So, I like that it helps make my old couch a little more structured. Unfortunately, you feel each section.

This is beyond what I expected. My couch is not even a yr old and the cushions would separate and sag. This was immediately fixed with this product. Buying one for my love seat now.

Longer and more sturdy than what I had under there before. Coupled with the lofty under cushions they solved my problem.

I got this because the frame we bought for our futon wasn't very good. I don't know if I just set the frame up wrong or what but sitting on the futon was awful! I got this to help with the dipping bars on the frame and it works like a dream! The futon is way more comfortable to sit on now. I did have to add straps to hold the boards in place but this definitely does exactly what I needed it to do!
