Health Mark IV18600 Pro Inversion Therapy Chair

Quick delivery. Easy to assemble. Sturdy construction. Had to rely on the pictures to assemble as directions were not clear. The pictures were not very clear but hardly any problem. I did it myself. Great for stretching my old spine and relieving pain in legs and feet. Don't have to stay on it for long periods. A few minutes will do the job and you can go back and get on it as often as you like. It is tall and is intimidating at first but I immediately learned how to mount. It is not hard to do.

I would actually give this 4 and a half stars, but that didn't seem to be an option. The product wasn't difficult to assemble. It took me about an hour and all tools, nuts and bolts were provided. This inversion chair really gives a good stretch on my low back, which is needed. The key is to not overdue it too quickly. Start slow, five minutes max for a while, before increasing time on it. I of course overdid it about the fourth day and had to back off a bit. I purchased this inversion chair rather than an inversion table, because an inversion table is hard on both my knees and ankles. The chair alleviates this issue completely! So, very pleased!The chair is well made with nice padded seat and back rest, as well as pads to hold the knees and ankles in place. It's easy to invert to the level you want just by leaning back, with a little guidance from the handle bars. The only reason I would give it a 4 and a half stars instead of five stars is the lap belt is not padded. For shelling out this kind of money, I would expect a more comfortable lap belt. You are hanging by this belt, why not make it more comfortable? This can be alleviated with providing your own padding, such as a towel, but I do feel this is an oversight on the manufacturer's part.

I was losing strength and feeling in my hands due to an auto accident. I would wake up in the middle of the night and my hands were NUMB! I purchased this chair in the hope that I could avoid neck surgery and it did the trick. It's been over two years since the accident and I now only use the chair occasionally. It's easy to use and very relaxing.

Just received this via FedEx today. Seems sturdy, well built, and does the job of getting me stretched out with the option of doing modified situps. Previously I had another inversion system which required boots for my ankles and placed all my body weight on my ankles. This was not working for either ankles or knees -- eventually caused considerable pain and swelling. So I searched for a replacement and found this -- now I have absolutely no strain on either ankles or knees. Very well designed. The directions are lacking. Considerable assembly is required. Clearer pictures would've been very helpful. Those provided are black in color and are not clear enough for us to tell what part goes where. Descriptions and instructions could've been much better. Also, instructions for using the machine could've been much clearer. I went crashing backwards and landed rather hard because I didn't understand how I was supposed to mount and lean back. But after some experimentation re both assembly and use, I finally have it figured out, and am very pleased with the product. 5 stars for product. But 2 at best for the manual.Now that I've used this a while, I feel constrained to warn users that it's very easy to fall backwards and land hard. I've learned that I must grasp the handles, place legs inside the rolls, carefully sit on seat while leaning forward in it, then attach seat belts. If you lean back in the seat while handling the seat belts, you're going to fall backwards suddenly and land hard. On the other hand, this becomes readily apparent after a short period of use and especially after a crash such as I had on my initial mount. Next, if you have sound ankles and knees, this equipment is not as good as those inversion seats that dangle you by the ankles. Without my old inversion equipment, I've lost the ability to truly dangle, something that greatly benefited my lower back. I cannot twist, or roll my head. Situps are reduced to a much smaller range of motion. However, for those of us with ankles and or knees that cannot endure being the sole source of support, this equipment is probably the best we can do, and I'm very grateful to be able to benefit from it.

I greatly appreciate the ability to hang from my thighs rather than my clamped ankles on the inversion table. I think this is a great prototype that needs some important modifications.1) The instructions tell you to sit against the back of the chair before fastening the lap belt. DON'T DO IT! Your chair assembly will flip back before you are strapped down and you will fall off on your head at an unhealthy angle for your neck. Instead, it is an awkward balancing act between backing up your butt enough to properly tighten up the belt while leaning forward to prevent your body weight to flip you back prematurely. There is definitely no need to raise an arm or two to make yourself flip back.2) As mentioned in many reviews, the belt is highly inadequate. It will cut into your thighs and become as distracting and painful as the above mentioned clamped ankles . I purchased on Amazon a "White Foam Roller 6x36 Round", cut it in half(about 2x18" pcs) , pushed a heated piece of flat metal in the middle to create a slit from one end to the next of one of the halves, removed the buckle from the belt, ran the belt through the slit and put the buckle back on. I now have a padded but firm support to hang from.3) For men only: refrain from the temptation of using the foam that's on the bar that fits under knees as rollers to get off the chair. The flattening of some parts of your body could created excruciating pain and maybe sterility.

Unit very well made and easy to assemble.

It puts a lot of stress on the knee joints and when you have got inclined-it is very hard to get back up.

This product is extremely sturdy, was relatively easy to put together, and has immensely reduced my crippling back pain. I no longer need to go to the chiropractor between using this inversion chair and doing pilates. This was one of the best things I purchased to improve my health and has saved me so much money in chiropractic adjustments and pain.
