I got these to replace the center 3 springs in a lazyboy. Purchased ones a little longer than needed, cut to size with boltcutters and installed in less than an hour. Strong hands and forearms required (and safety glasses recommended). Fixed for a fraction of the cost that lazyboy wanted. Springs seem to be of adequate quality and work well. Very pleased with the purchase.

I purchased these springs to repair a broken spring on my 14 year old Lazy-Boy recliners.
There are four zigzag springs in the set/pack, In my case I decided to replace only the two center springs with the new springs. What I noticed was that the one that had not broken was stretched a bit more than the two outside springs (this might not apply in all cases), I confirmed this later with my other recliner with no broken springs and a brand new spring set that was recovered from a lazy boy warranty repair!

Finding the correct size:
The 19in spring was a perfect fit for my 21in seat frame measured from the inside of the frame front to back and also taking a cloth measuring tape and measuring the spring on the outside of the arch end to end.

To replace and install:
I removed the seat from the chair frame. there are 8 wood screws total, 4 per side holding the seat to the chair mechanism. and there are 4 more machine screws holding the footrest or at least there should be (mine had one wood screw and 3 machined screws installed by the factory on one of my chairs!).

There is no need to remove any upholstery to replace these springs, but you will need to remove the spring set/pack from the seat frame. Use some gloves and be careful, take note of protecting your eyes and others due to the tension on the springs and parts of the springs. You can buy the tool made for this or you can do this by hand if you have the finger and hand strength or like me have the following or make something that can help release the springs.

In my case I had an old automotive brake tool used for removing and installing brake drum springs and with this I used one of the first spring clips removed by hand to grab the spring in the same matter they are install allowing pressure of the installed clip to be released. This allowed me to remove and reinstall the set with ease being that the first spring or last spring clip would have less tension on it while removing or reinstalling respectively, if you have extra clip/retainer, which I later did it made it that much easier.
As for the installing the zigzag springs in the set, it was pretty straightforward, I pried the old retainers off with a couple of flat bladed screw drivers to get it started and some needle nose pliers to finish off the removal and reinstalled by crimping them carefully back on with the same pliers. Also, make sure that you bend the end of the spring at the front catch so that the spring does does not slide off, I forgot to do this on one set and it slipped off later. If you have bench vice this helps hold the spring while bending the end inwards, does not need much to keep the spring from moving laterally - side to side!

The final result was very good, a firm seat, no sagging and possibly a fix for another issue I noticed with the lazy boy's fabric and material ware in the middle of the seat where the material had been folding over at the back of the seat and causing surface ware, which I never thought about as possible issue that could be related to the spring sag!

Rating:
4 stars - finding these here was great, shipment was great, but a day or so later I wanted to rebuild my other recliner and the price of the spring went up, which happens every time once their/the Amazon system sees activity on an item, their BOT increases the price of the item within seconds of the first order! Other than that I would recommend these, not impossible to replace and sure beats buying new chairs!
Update, the price dropped and so I bought 4 more for other repairs on several other chairs that yet to have a spring break, but have signs of sagging. rating bumped to 5 stars.

I purchased two of these springs to replace broken ones in my sofa. Without having the proper tools or tearing my sofa apart more this was a simple, but strenuous fix. Everything I needed came in the package including clips and the end clasps.

So far I am pretty happy with the springs. They are a lower guage than the original springs and the zig zag pattern is different but under the somewhat broken down sofa cushions you really can't tell the difference.
I would give this product five stars if it came with any kind of instructions of guidance, which most people who would attempt this repair wouldn't need, but some of us who are more comfortable on the couch than under it could probably use the pointers. Also the pricing is a little high.
Overall"‹ solid quality product.

One of the springs broke in my home office chair, so I measured the exact length of the broken spring (20 inches) and ordered this item to replace it. The Amazon ordered arrived on time (with 2-Day delivery, it showed up Sunday morning) and I easily replace the old spring with the new one.

The spring part itself was an exact match for the broken spring, so the stiffness matched up well also. However, the ends of the spring were obviously cut off from a much longer spring as I needed to trim one end with a dremel tool so I could slip it into the already installed brackets. The other end was cut a little too short (see photo), which means it could possibly slide out of bracket. I used a plastic zip tie to hold this end of the spring to the adjacent spring to help prevent any lateral slippage at the end of the spring with the short cut.

In all, this was a cheap fix for my office chair and I'll have to see how well it holds up over time.

Repaired a 20 year old La-Z-Boy Grand Canyon Recliner perfectly. I weigh 265 lbs and the Great Dane weighs 140, so I guess it will be the ultimate test of spring survival with me and my lap dog......get back to you on that one. Already repaired and reinforced several weakened wooden joints, rocker springs, and now these seat springs. Grade 4 fabric starting to show some wear in spots, so I doubt I will get another 20 on it, but still looks good after all these years. Used the 21 inchers on this bad boy, and be careful, wear gloves, eye protection because this spring wants to snap around when you are positioning it. Make sure you have it well secured on at least one end before stretching it out. And replace the 'stay wires' while your at it.
