Whether or not inversion therapy will work for your back pain will depend a lot on your individual problem. But if you've got chronic pain and want to give inversion therapy a try, this table would be a good choice. It is extremely well made and sturdy. I had a cheap inversion table years ago, and while they all perform the same basic function, the cheaper one looked and felt flimsy. This one feels like it could hold an elephant. You could spend less, and you could spend a lot more. This model and brand meet at the junction of cost value and quality of construction. I do not believe you will find a better built unit at any price.
With any of these tables, forget about folding them up to put away. That's just not realistic, especially on a regular basis. So it's going to be sitting out, and better to have a nice one.
Also, forget about putting it together in 30 minutes. If you put 10 of them together, you could probably get the 10th one done in that time, but count on more like 90 minutes to assemble it. It's not hard, but you do have to read the instructions carefully and figure things out as you go. You'll probably be better off using your own tools rather than the disposable ones they send with the unit.
The leg holders on this unit are as comfortable as can be expected. My ankles start to hurt after 3-4 minutes, which is all I do at one time anyway. I discovered that a few short sessions throughout the day are better than one long one. After a long session, I would sometimes feel worse.
I've had mine for about 2 months now, and I definitely see improvement in my back. I still have pain, but it has made enough of a difference that I decided to keep the unit when the free trial period was over. It would be quite a job disassembling, repackaging, and getting it shipped anyway. lol.
I bought mine directly from Teeter's web site, where they also offered free shipping. They also included the (useless) accupressure knob attachments and the lumbar stretcher, plus I was able to avoid sales tax. Mine was delivered intact and undamaged. Others have complained of damage during shipping, but that is going to happen from time to time when you order anything big and heavy online. It is important to inspect the box when it arrives and to refuse the shipment if the box is badly damaged (call the shipper to have it picked up if it was left without signature).
When I bought mine, the Web site urged me to upgrade to the model 960 for another $100. I actually thought I had selected the upgrade option, but somehow I ended up with the 560 and now I'm glad I didn't spend the money on the upgrade. The main difference is an attachment system to make it easier to get in and out of the table. I have found that it is plenty easy to get in and out, plus the bend/stretch motion required is one that you should be doing in conjunction with using the inversion table anyway.
It may not work miracles for everyone. I'm rating the table in terms of the quality of construction, ease of use, and appearance. For that I give it 5 stars.
