How to choose an inversion table

1. Weight limit and height range

These are the first filters, and they are not flexible. Compare your own weight and height with the maker's published figures and leave margin.

• Every Teeter table we cover (X3, LX9, X1, EP-560) is listed at 300 lb and 4 ft 8 in to 6 ft 6 in.
• Innova's ITX9600 and ITX9800 are listed at 300 lb and 4 ft 10 in to 6 ft 6 in; the ITX1200 is listed at 350 lb and the same height range.

Innova's FAQ also notes that your height setting on the table may not match your actual height, because the balance point depends on your weight distribution. If you are outside the limits, see tall people and heavy-duty tables for what we could and could not verify.

2. Ankle system

The ankle lock is what holds you on the table. Look for one you can reach and close easily, and plan to test it every time. Teeter's manual tells you to hear, feel, see and test that the ankle lock is snug and secure each time. Two designs show the range: Teeter's EZ-Reach has an extra-long handle that Teeter says reduces the need to bend forward, while its T-pin closure on the X1 and EP-560 means you reach further down. Innova uses reversible holders, straps or an extended-handle system depending on the model.

3. Angle control

You want a way to limit how far the table rotates. Teeter uses a tether that you set before you lie back; on the X3 it has markings at 20, 40 and 60 degrees. Innova uses a pin with several positions, six on the ITX9600 and ITX9800, and three on the ITX1200. Both are set before you invert. See what angle to start at; the sources we read say to start small.

4. Height and balance adjustment

Look at how the table is adjusted to your height and balance. Teeter's manual describes a main shaft with a locking pin; Innova describes a height adjustment tube plus an adjustable headrest. The point is that you can set it, test it, and change it by one step at a time. The steps are in how to assemble and adjust an inversion table.

5. Folding and space

Every table we cover folds. Teeter lists in-use footprints of about 81 x 28.8 in with 86.5 in of height, and folded sizes of 20 x 28.8 x 66 in on the X3, X1 and EP-560. Measure your space for both. See best folding inversion tables.

6. Warranty

Teeter states a 5-year full warranty, included, on its tables. Innova states a one-year limited warranty. Read the terms yourself, and compare what the maker states rather than what a seller advertises.

7. Extras that are worth less than the basics

Heat, vibration, accessories and cushions are optional. Teeter, for example, sells an EP-560 bundled with a heat and vibration cushion. They do not change the limits above.

Safety

Inversion tables are not for everyone, and the research on them is limited and mixed (Cleveland Clinic). Read who should not use one and talk to your doctor before you try one if you have any health condition.
