Technical specificationsThis is a simple massaging chair that can mimic human hands of a professional masseuse. Because it comes with many roller mechanisms and advanced kneading techniques it can focus on different areas of the body. The model features a 30-inch roller that can reach the entire length of your back. The rollers which mimic the feel of human hands can reach the base of your neck and go all the way down to your lower back. You can further match the rollers to the length and curves of your body by adjusting between two modes: medium and narrow. It also involves adjusting the height and width of the chair so that it properly fits your body type. The shape of the seat can easily follow the natural S shape of your spine so that you will feel more comfortable while enjoying a relaxing massage. The seat of the Osaki OS-4000 is designed to provide support to your back, lumbar area and your neck as well and it also improves the quality of the massage.
Massage featuresIf you enjoy receiving a relaxing and soft massage, one that is not too firm, this model is a great choice for you. According to some customer reports, this model is not strong enough to deliver a very firm massage. Nonetheless, it comes with many features that can target the most important parts of your body, to ensure that you receive an amazing whole body massage. The 48 airbags are designed to offer a deep tissue massage. The airbags can cover the major parts of your body, including your shoulders, arm, lower back, neck, calves, hip and your feet and they are strategically placed throughout the unit to improve the quality of the massage. There are 10 airbags for your calves, another 10 for your feet, 2 for the back, 2 for the shoulders, 3 in the hips, 3 in the neck and another 3 that cushion the seat. The mechanical rollers target the main acupoints in your feet and other parts of the body. So, if you are the type of person who spends a lot of time standing up or if you tend to practice a sport regularly, you will enjoy receiving a proper foot massage.
Programs and massage techniquesZero Gravity is one of the most popular features in the massage technology. This feature was developed by NASA with the main purpose to relieve tension and back pain. It doesn’t focus on a specific area of the body; it actually displaces pressure across the body to eliminate tension in the muscles. Osaki has adopted the zero gravity technology to give you the ultimate massage experience but there’s more to come. This model features several massage programs, such as kneading that help relieve muscle tension; rolling, which is used at the beginning or at the end of the massage sessions to warm the muscles; clapping eases muscular tension and pain, while tapping helps reduce tension accumulated at the neck and head area. There are also 5 massage styles including Swedish, pulse mode, air bag massage, vibration and the most popular one, which is Shiatsu and 5 massage groups: circulation, smart, healthcare, therapy and relax. The leg rest is a great addition because it can reduce tension in soles and calves. It also comes with a sensor that scans your body type so that it can provide the perfect fit for your body.

Complementary therapiesThe unit uses heat therapy to ease back pain. What’s worth mentioning here is the fact that the heat therapy is only for the lumber area, and not other areas of your body. The heated seat can make your back muscles soften and relax while easing pain and improving blood circulation. So, if you want to improve your overall well-being or reduce tension in your lower back, this is a great way to start or end your day. Unfortunately, this particular model doesn’t feature other types of complementary therapies, such as chromotherapy lights and others.
Convenience featuresOne of its main advantages is the fact that you will benefit from the Body Scan technology. You are probably already familiar with the terms “body scanning” but for those who don’t know how important is this feature, you should know that the body scan system can scan major body parts to provide them with a proper massage. For instance, if you suffer from back pain and you want to reduce pain and eliminate tension in the muscles, the chair can scan the area to help alleviate back problems in just a matter of minutes. We like that you can control the programs of the massage from distance by using the wireless remote control. With a wireless remote control, you can easily control the major functions even when you are in the zero gravity position.
DesignThe model is made of high-quality materials. The chair itself is made of leather and it has a metal base. At first glance, it looks very modern and stylish but you will soon notice how simple it really is to adapt it to any type of setting, whether you choose to use it for commercial or everyday purposes. You can choose from a variety of colors, like black, brown, charcoal and crème. Most of them are neutral and earthy colors so they go well with almost all interior styles. It is bulky and quite large so it doesn’t fit a narrow and tight space. Its dimensions are 52″ x 31″ x 34″, and 76″ when fully extended.
Warranty and supportThe warranty offered for the product is short, considering the fact that most models that cost over $2000 include a 5-year warranty. However, the good news is that the Osaki company provides a warranty that backs up the product no matter in what type of environment you’re planning to use it. So, whether you are planning to use in a commercial setting or just an everyday seating, you can rest assured knowing that the product will benefit from the warranty no matter what. As for customer support, it’s important to note that there’s a separate page for massaging chais. There you can find an email support address as well as a telephone number so that you can call the representatives in case you have questions.
