      What are the health benefits of massage chairs?

      • Studies have shown that just two 15-minute massage chair sessions per week reduced anxiety and job stress levels, while increasing alertness and general calmness. Additional studies have revealed that massage chair use reduces blood pressure and blood sugars. Finally, massage chairs reduce pain and tension (e.g., minimizing headache symptoms and muscle tension).

      How long will the chair last?

      • Infinity Massage Chairs are manufactured with durable framework and tremendously well-engineered technology in order to ensure longevity. With proper care and occasional maintenance, your chair will provide many years of wellness.
      • In fact, we're so confident in our chairs that we provide a three-year peace of mind warranty, with an optional one- or two-year extended parts warranty available for purchase.

      The chair seems big, is it going to fit in my house?

      • The dimensions of each chair, both upright and reclined, can be found on the product page under the Features tab.
      • Most Infinity chairs are equipped with our innovative space-saving technology, which either moves the chair forward on a track system or on its axis in order to conserve space. Select models have zero-wall space-saving mechanism, which allows you to place the chair as close as 4" from a wall and still fully recline without concern for additional space.

      How does delivery work?

      • We ship anywhere in the United States. Our chairs come with complimentary standard curbside delivery, meaning the carrier will deliver the chair just outside your home. We also offer white glove delivery for an additional cost, which includes inside delivery and assembly in the room of your choice (up to two flights of stairs).

      When can I expect my chair to arrive?

      • If you select our free standard shipping option, you should expect delivery within 7 to 10 business days from the date of your order. If you choose white glove delivery (includes delivery and assembly in the room of your choice), you should expect delivery within 12 to 15 business days (this is due to the more involved nature of white glove assembly).

      What is the warranty and what does it cost?

      • Our standard warranty comes with all of our chairs and covers the costs of any replaced parts, structural framework, and labor on your chair during the first year at no cost to you. All customers also have the option to add on a one- or two-year extended warranty for parts only at the time of purchase.

      What is the return policy?

      • We offer a 30-day return policy on all Infinity Massage Chairs, which goes into effect from the date of shipment. All items for return should be in their original condition and packaging. Infinity customers are responsible for return freight shipping, as well as a 15% restocking fee. If you cancel after the product has been shipped, you will be charged the cost of the outbound and returned shipping costs. If you cancel before the product is shipped you will be charged a 3% transaction fee.
      • Once we have received and inspected your returned product, Infinity will issue a credit for your total purchase amount, minus both the return shipping and restocking fees. The customer will be responsible for any damages noted upon return, and could incur additional costs.

      How often and how long should I use my massage chair?

      • We recommend that new users ease into their massage routine with 10 to 15 minute massage sessions, two to three times per day. As you become increasingly comfortable and familiar with your massage preferences, you can experiment with longer, more frequent massages. We find the sweet spot for regular users is around one 30-minute session every day.
