YOUR PRIMA13 Posture corrector

  • Your posture corrector comes with a pair of underarm pads, in case you’d like to have protection around your armpit area

  • It is designed to correct the alignment of your spine by stabilizing your shoulders and neck helping you develop a good posture and reduce chances of slouching 

  • Use it when sitting or standing – at work, at home, in the gym or when outdoor. 

  • Try first wearing the posture corrector without the pads; most people will find it comfortable enough and don’t need to use the pads (watch the demo video to learn how to install them)

  • It comes in two sizes: Small (chest size: 27-40 inches, 68-102 cm) and Large (chest size: 38-45 inches, 96-115 cm)

  • To measure your size (hopefully you did this before your purchase), run a measuring tape from armpit to armpit and around your back (above the chest for the ladies)


setting up the posture corrector (watch the demo video)

set up prima
  • The posture corrector will arrive folded in a plastic bag; laid it open on a table so that the leather part with the logo is facing up.

  • Detach one strap and insert it into the buckle with the velcro side facing up

  • Run the strap through the buckle and attach the strap to the outer velcro, making sure that the strap is well aligned and not twisted

  • Do the same with the other strap and your posture corrector is ready to wear!

wearing the posture corrector (watch the demo video)

  • Wearing the posture corrector is easy and it will become second-nature after a few times you put it on – you can also wear it under cloths, it’s invisible and only you will know

  • You can put it on like if it was a backpack: insert one arm first, bring it over your shoulder, then insert the other arm from the back 

  • Alternatively you can let it drop from above and it will get into position naturally

  • To adjust it to your chest size pull the straps and attach it to the velcro in the desired position

  • You can also make little adjustments by pulling up and down the posture corrector


getting best results

  • REMEMBER: the corrector is not a rigid cast that "forces" you into the straight position; it acts instead as a "gentle reminder", especially when you slouch 

  • If the corrector is well adjusted (tight, but not super tight that it blocks your blood circulation!) you will feel a slight discomfort when slouching – and that means it is doing his job!

  • Start by wearing it for 10-20 minutes per day and increase the gradually, as it feels more comfortable

  • Without you knowing, you will develop the so called "muscle memory" 

  • Within about 10-15 days of using it you will catch yourself as having a good posture even without wearing the corrector! 

  • If after a while you realize you are slouching again, wear the posture corrector again and your muscle memory should return fairly quickly this time ☺


other information

  • The posture corrector can be machine-washed (at 86-104 Fahrenheit, 30-40 Celsius) and can go into a drier. This is convenient!


  • Do not use while sleeping (or laying horizontal)

  • Especially if you suffer from serious back pain or are under special care, use this product only in coordination with your orthopedist or chiropractor for specialized advice and recommendations.

What is ‘muscle memory’?

In this case is when your will start having a good posture even when you are not wearing the corrector. Your body will remember what it feels to keep your spine straight and will start going back to that healthy position on its own. This may surprise you!

When I wear the posture corrector I still can slouch, why?

Because the corrector is not a rigid cast that "forces" you into the straight position; 

it acts instead as a "gentle reminder", especially when you slouch. It makes you feel slightly uncomfortable when you slouch making you go back to a good healthy posture and this is how your body will learn and develop muscle memory. 

How long before I can see results?

You will feel immediately as soon as you put it on and every time your posture is good. You may start feel some benefits already in a few days. We do recommend to use it for 10 to 15 days consistently for best results.

I feel the corrector is a bit uncomfortable, what should I do?

Make sure the straps are not too tight, adjust it also by moving it slightly up and down. Make sure you got the right size. If none of these tips work, get in touch with us and will do our best to help you.
