Inversion table vs back stretcher

How they differ

	Inversion table	Arched back stretcher
What it does	You are secured at the ankles and tip back; the angle is set by a tether or pin	You lie over a curved form that arches the back backwards
Head below heart?	Yes at larger angles, which is why the medical cautions are longer	No
Adjustable?	Yes: angle, and on many tables the height setting	Some stretchers have steps or levels; we did not verify any maker's claims
Maker specs we could verify	Yes: weight limit, height range and warranty on Teeter and Innova pages	None: we have not verified any stretcher on a maker page
Space	Floor space, though several fold (folding tables)	Small

What independent sources say

• The two are not the same kind of device. BackGains, a strength-and-conditioning site, groups arched stretchers and inversion tables together as "mixed-evidence equipment" and says both provide temporary relief but lack evidence of lasting benefit without accompanying strengthening. It describes the stretcher as doing the same thing as lying lengthwise on a foam roller or draped over a rolled towel. That author is a coach, not a doctor, and the site earns affiliate commissions, so read it as one opinion.
• For tables, Cleveland Clinic says there is limited quality evidence for the benefits people report and that studies have been small with mixed results. WebMD says evidence is mixed on whether tables are an effective treatment for pain and that injuries are fairly common, most often due to operator error.
• For clinical guidance, the UK's NICE low back pain guideline (written for the NHS, 2016) says not to offer traction for low back pain with or without sciatica, and to encourage people to continue normal activities and to consider a group exercise programme. It is about care offered by health services, not about home devices, so it does not rule either device in or out; it does show that guideline-writers put movement and exercise first.
• We found no trial of arched back stretchers. Marketing words such as "decompression" are not evidence that a stretcher separates your vertebrae.

Which should you choose?

1. If you have a health condition, or any pain that is not simple stiffness, ask a doctor or physiotherapist first. Cleveland Clinic notes some physical therapists use inversion in their practice and suggests trying it there before buying for the home.
2. If you want a device with published weight limits, height ranges and warranties, compare tables. Start with how to choose an inversion table or the picker.
3. If you would rather not tip back at all, the sources we read point to movement and exercise as the lasting part of any routine, whichever device you use. A seated option is covered in inversion chair vs inversion table.
4. Whichever you pick, start gently. See what angle to start at and how long to use a table.

Why there is no stretcher roundup here

Our rule is that a product is recommended only when its weight limit, size and warranty are on the maker's own page. We have not found that for a back stretcher, so we have no recommended stretcher and no stretcher links. The tables we have verified are in best inversion tables.

Safety

Inversion devices are not for everyone. Read who should not use an inversion table first, and talk to your doctor before you try one if you have any health condition.
