A gentle, effective way to ensure your mouth stays closed during CPAP or bi-level therapy with a nasal or pillow mask. This is a medium-sized chin restraint.


Help keep your mouth closed while you sleep. Probably the most stable of chin straps, the unique, multi strap design holds it securely in place, and gives lots of chin and lip support.

  • Adjustable top strap
  • Adjustable back strap
  • Larger chin cup for more support
  • Bottom lip support as well as chin
  • Very stable multi-strap design
  • All elastic material for maximum comfort

What size do I need? Measure around your head, from under your chin to the crown of your head going just in front of your ears (above your forehead), and back to the starting point under your chin.

Median Sizes are:Small fits where the chin to top of head measurement is around 54cm.

Medium fits where the measurement is around 60cm.

Large fits where the measurement is around 66cm.

Further lesser or larger adjustment is available on each chin strap size. The circumferences shown are the medium size for each chin strap. Chin straps help to minimize the problems that occur if air leaks from you mouth whilst using nasal CPAP. These include: a dry mouth or the feeling of air bubbling through your lips as you go to sleep. Chin straps can also sometimes help prevent air swallowing (aerophagia) and the discomfort it causes.

Q : Can you please advise washing instructions without damaging stretchiness ?
A : Wash weekly in warm soapy water, rinse and dry but not in direct sunlight. The Seatec will stretch slightly over the first month. 

Q : Can we see a diagram how worn?
A : It goes over your head and under your chin. 

Q : Does the Chinstrap go on outside of your CPAP mask or on the inside. In other words what goes on your face first?
A : Mask, then chin strap 

Q : Will this item help reduce snoring if used by itself?
A : This will reduce minor snoring if the snoring is caused by muscle relaxation. This is not a prescribed therapy for snoring or sleep apnea. If the snoring is consistent it is best to have a chat to your GP.
