Frequently Asked Questions
How It Works
See how the CorePlus™ Posture Corrector transforms slouched, strained posture into strong, supported alignment.
Gentle Pullback
The figure-8 strap design gently pulls your shoulders backward into proper alignment. This reduces the forward slump that causes neck and upper back strain.
Supportive Structure
The contoured back panel supports your upper spine and holds your shoulders in a healthier position. This takes pressure off overworked muscles and helps you maintain better posture naturally.
Custom Fit
Fully adjustable straps let you control the level of support and tension. You can start light and increase as your muscles adapt, ensuring comfort and effectiveness every time you wear it.

- Designed for long-lasting comfort — anytime, anywhere
Your Path to a Stronger, Pain-Free Posture
Engineered to ease pain, improve alignment, and boost daily comfort.
Eliminates Poor Posture at the Source
Years of sitting at a desk, looking down at your phone, or standing with rounded shoulders can place extra stress on your upper back, neck, and shoulder muscles. This ongoing strain may lead to discomfort, stiffness, tension headaches, and a forward slump that makes you feel tired and uncomfortable.
- Targets slouching and upper back strain
- Provides supportive alignment and gentle correction during work or rest
- Supports natural posture better than relying on willpower or reminders alone
Naturally Restores Healthy Upper Body Alignment
Daily desk work, phone use, or long hours without proper posture support can slowly strain your neck and upper back, pulling your shoulders forward. Over time, this may lead to discomfort, muscle imbalance, tension, and pain that makes it harder to sit or stand comfortably.
- Reverses years of strain from poor habits and misalignment
- Strengthens postural muscles naturally
- Promotes lasting straightness and tension-free movement without discomfort
Natural, All-Day Support and Posture Relief
Relying on reminders or trying to "just sit up straight" may only work temporarily — it doesn't address weak postural muscles, ingrained habits, or ongoing strain. Many people stay stuck with temporary fixes without real support.
The CorePlus™ Posture Corrector offers a natural, non-invasive way to support alignment and retrain your posture, helping reduce discomfort while you stay active and comfortable.
- Provides lasting support without harmful medications
- Comfortable enough for all-day wear
- Supports your posture naturally through every movement
