Questions
Good to know.
Yes. A professional team delivers to the room of your choice, assembles and positions the chair, tests it, and removes all packaging, included across the continental US.
Not automatically. A massage chair is a dual-purpose item, so it becomes eligible only when a licensed provider documents medical necessity in a Letter of Medical Necessity. Several of our chairs are listed on Burst, a platform built to handle that review. We are a massage chair dealer, not a medical or tax advisor, so the decision rests with your provider.
Flexible monthly financing is available through trusted partners, subject to approval, from about $361/mo over 36 months.
If it is not the right fit, return within 30 days of delivery in original condition. We also offer a Chair Upgrade Program that credits your chair toward a future model.
5-year manufacturer warranty: 3 years full service plus 2 years parts.
