Inada Flex 3s Full Body Massage Chair Review

The popular Inada brand offers this HCP-S373 (B) Flex 3s massage chair at a retail price around $4000. When you first look at the chair, it appears to be a plush modern arm chair in synthetic black leather with a comfortable seat and large leg rests. Although it is large, it would fit nicely into many rooms of the house. Once you sit down and activate one of the many massage features, you will understand why the high price tag just may be justified.

Compared to other massage chairs in this price range, the Inada Flex 3s model also features anti-bacterial fabric, full body air massage and a special shoulder and a collarbone focus feature to relieve stress better than ever before.

Inada flex 3s Massage Chair Specifications

 This large massage chair from Inada is 50 inches long, 41 inches tall and 33.5 inches wide. It weighs only 200 pounds so it is a bit more maneuverable than other chairs on the market that may weigh 300+ pounds instead. There are also wheels on the back of the base so it can be tipped, balanced and rolled into position more easily.

The Inada Flex 3s massage chair is fashioned from black or dark brown manmade leather that is both dirt resistant and anti-bacterial. Although easy to clean with a damp cloth, these extra treatments make it more comfortable for everyone in the family to use.
