    This is by far one of the nicest inversion tables that I've tested. There's no wobble in this table. I've tried some "high end" tables in the past, but none have felt this sturdy. This table also looks great and is made of quality material. We use the table for stretching, but it also gives you the option to perform inverted sit-ups. The locking mechanism is strong and secure. Don't worry about the assembly. I had it put together in 20 minutes. Pros: Price, Sturdy Construction, Looks Cons: A little bulky. Does not fold up.

  • Everything I expected. Excellent

    When shopping for my inversion table I researched many brands and models on line. I originally conciderred one of the eBay knock-off tables. But after some concideration I decided this would be a permanent piece of equiptment for me, one that I will leave setup and use for many years. The weight alone told me this thing was a substantial piece of hardware. I read the available reviews on the net. My own personal experience is that it performs just as it is supposed to. I have been using this for over 1 month now. I use it every day. I expected to get benefit from this machine as far as stretching out the aging body and that is what I have experienced. I normally use it before bedtime. The first time I used this it was strange getting out of it and walking.... I noticed that I was walking with my body straight, shoulders back more .... and I fealt taller! That is not something I was expecting .... it actually was very surprising to me. I was not attempting to walk more upright, it just naturally happened! I read some comments. and I think at least one person stated they broke the locking feature early on. I am not sure exactly how they used it or if they were gentle or rugged in the transitions. But reading their review was good because it made me more attentive to the locking positions. I have had no trouble at all with the locking positions or releasing the locking mechanism. I am carefull when using the locking positions that I move from one position to the next SLOWLY, Controlled, not just throwing myself back and locking in at full speed/full weight. If you use it this way I would expect this to last many years. When releasing from a locked position you should move your position slightly whichever way that takes the full weight off the mechanism .... ie: take the tension off before pulling the lever. This also makes the transition very smooth and the lever will move freely/easily. That is just a couple tips that I hope you will find useful. Incidentally, I purchased a Teeter Hang Ups vibration/heating cushion for mine and it fits PERFECT .... for anyone that thought of adding one, I did a bit of research and measuring before I purchased. I was buying somewhat blind from the net, but was very pleased to find the cushion fits well and works great with this machine! No regrets at all on my purchase, glad I bought this inversion table!

  • Exceptional!

    We researched these long and hard before purchasing. We have not been disappointed and it is GREAT, superior manufacturing! Excellent scale and balance - easily adaptable to both my size and my husband's height - QUICKLY! It is not bulkier than I expected; it is just a little larger in scale. It is not delicate, it's sturdy in all the right ways. The padding is better than expected, the gizmo that controls the motion is great quality. It's a teeny bit heavy for me (but I don't like lifting stuff that much anyway.) Hubby says it was quick to put together and worth every penny. Glad that we spent the time and money to get the RIGHT one the first time. THIS IS THE BEST ONE I HAVE SEEN - the one we had used was $700 more and not this nice. Sorry to rant and rave - but I feel so good, I could just kick myself for not buying one sooner~ aaah! and my back thanks, too! It also is stylish - for anyone besides me who cares about that stuff. It's kind of architectural and we have yet to hang clothes on it...unlike our treadmill. SIX PACK ABS, here I come!

  • perfect except 1 super major flaw

    2 little screws hold the footpiece to the downtube which go up to the backrest..these little screws are not secure enough to hold anyones weight!! they stripped out immidiatly. if your gentle it doset matter but it will wobble slightly. if you exercise on it, this will eventually wear the cross bar out and the unit will need to be replaced only to start all over again!!!! design flaw!!!! sorry, otherwise 1 excelent product. Eventually i will get a solid metal crossbar on my own, replacing the hollow one and drill it through with a nut and bolt deal, and some threadlocker. then this will be epic!

  • The real deal

    I have done my research and found this inversion table hands down nicer than the 'popular' competition. Nothing flimsy about this product. Start with the table itself. It's not plastic or cloth stretched over a frame. It's a padded bench. Frame is heavy and sturdy. I found it easy to assemble and operate. Ankle adjustment is easy to get to and operate. Same for the tilt mechanism on the table itself. User height adjustment is also quick and sturdy. Shipping from CA to PA was fast and no parts damaged or missing. Price was by far the best I could find and I researched ad nauseum. I use it after workouts at about 3/4 tilt for 10-15 minutes. I use the time to practice meditative breathing. While I'm no doctor, it works for me and I look forward to using it.

  • Decent, but not worth the $$

    I was in the market for a inversion table. I figured I would spend the extra money and get this unit, it had some nice features the lower priced unit didn't have such as full inversion, ability to work the abdominals, and what seemed to be a nice ankle retention system. Firstly the unit is huge and extremely heavy, I expected this somewhat as it has to support the weight of a suspended adult. But the unit takes up a ton of space, both in regards to a rooms floorplan and also vertically. This went into my basement with 8' ceilings and my ceilings were not high enough to clear inverting a 5' 8" person. I can't really blame the manufacturer for this anyway, you can only fit so much into a 8' ceiling, but thought it might be good info for anyone else. Since the unit does not fold up it takes up a lot of permanent space, without the option of stacking/storing it somewhere. The backrest is very uncomfortable. Many units I saw had lumbar pillows, which would mimic the natural lordosis of the lumbar spine. This one was just a flat bench, so when inverted it felt like I was extending backwards and this tended to put stress on the posterior facet joints of the spine, resulting in discomfort and what I would foresee as eventually being pain from constant pressure and irritation. The ankle retention method left much to be desired. It wasn't tight enough so I always felt like I was slipping out of it. I'm average sized, 5' 10" and 190 lbs., size 11 foot. My wife, who is more petite, could not use this unit as her ankles slipped right out. The latching mechanism is poor as well. It was difficult to disengage the lock, it was easier to engage the lock but occasionally it would click, but not lock. My wife had one episode where she thought it had locked, but it ended up unlocking and forcefully swinging her around, not good. Overall the unit isn't bad, it just needs a bit of engineering TLC. Even if these problems were corrected I don't think I would buy the unit again. I did return this unit as defective because of the latch issues. But the unit was just way too huge and bulky for my needs. I may try a smaller foldable table, but more likely I will just get a pair of gravity boots.

  • Every household should own one

    The table is sturdy and easy to assemble. Think about it. We as humans are upright compressing the spine throughout the day. Why not decompress? I use it in mornings as soon as I awake, evenings and prior to going to bed. I believe every household should own a Inverse Table.
