There’s no data on which type of corrector works best, and Rodriguez says any corrector can be beneficial if you use it properly while going about your daily routine (no, you shouldn’t wear one to bed). If you’re ready to give one a try, here are some things to look out for:

• Does it target your weak areas? There are different posture correctors for different parts of your body. The most common are for your shoulders, your cervical thoracic junction (where your upper back meets your neck) and your lumbar spine. If you’re not sure where your weak areas lie, take a look at your posture from the waist up to pinpoint the origins of your slouch. Is your back arching too much? Try a corrector with lumbar support. Are your shoulders hunching or is your neck drifting forward? Consider one that helps keep your shoulders down and back. If you’re truly lost, Rodriguez suggests seeing a physical therapist to help you choose one that fits your needs and focuses on the areas that demand the most support.

• Does it fit comfortably? You want breathable material that feels good on your skin and doesn’t cause chafing. It shouldn’t contort your body into unnatural positions or hold you in place too strictly. “If it’s not comfortable, it won’t be effective because you’re not going to use it,” says Rodriguez.
• Can you use it by yourself? You don’t want a contraption that requires a PhD to operate. You want to be able to put it on, adjust it and take it off without relying on anyone else to help you tighten a strap or lift it off of you.
• Does it look okay? Take a peek at how it lays under your clothing. Most likely you want your posture corrector to be hidden from view.
• Is the price right? Posture correctors with a tech component tend to be more expensive than other types. For more at Posture corrector USA
