In thermodynamics, heat is energy in transfer between a thermodynamic system and its surroundings by modes other than thermodynamic work and transfer of matter. Such modes are microscopic, mainly thermal conduction, radiation, and friction, as distinct from the macroscopic modes, thermodynamic work and transfer of matter. For a closed system (transfer of matter excluded), the heat involved in a process is the difference in internal energy between the final and initial states of a system, and subtracting the work done in the process. For a closed system, this is the formulation of the first law of thermodynamics.
Calorimetry is measurement of quantity of energy transferred as heat by its effect on the states of interacting bodies, for example, by the amount of ice melted or by change in temperature of a body.
In the International System of Units (SI), the unit of measurement for heat, as a form of energy, is the joule (J).
With various other meanings, the word 'heat' is also used in engineering, and it occurs also in ordinary language, but such are not the topic of the present article.

Massage is the rubbing or kneading of the body's soft tissues. Massage techniques are commonly applied with hands, fingers, elbows, knees, forearms, feet, or a device. The purpose of massage is generally for the treatment of body stress or pain. In English-speaking European countries, a person professionally trained to give massages is traditionally known as a masseur (male) or masseuse (female). In the United States, these individuals are often referred to as "massage therapists". In some provinces of Canada, they are called "registered massage therapists."
In professional settings, clients are treated while lying on a massage table, sitting in a massage chair, or lying on a mat on the floor. There are many different modalities in the massage industry, including (but not limited to): deep tissue, manual lymphatic drainage, medical, sports, structural integration, Swedish, Thai and trigger point.
A recliner is an armchair or sofa that reclines when the occupant lowers the chair's back and raises its front. It has a backrest that can be tilted back, and often a footrest that may be extended by means of a lever on the side of the chair, or may extend automatically when the back is reclined.
A recliner is also known as a reclining chair, lounger and an armchair.
Modern recliners often feature an adjustable headrest, lumbar support and an independent footstool that adjusts with the weight and angle of the user's legs to maximize comfort. Additional features include heat, massage and vibration. Some models are wheelchair accessible.
Recliners can also accommodate a near supine position for sleeping (making them multifunctional furniture), and are common in airplanes and trains, as well as in homes.

We received the chair in 1 week from order. Setting up was not difficult, my husband put together. It is really comfortable, I like the sleek design of it, it doesn’t take up a lot of room and easily to move around. The vibration massage is very relaxing. Very happy with this purchase.

Even though my chair came without instructions but it was easy to figure out It does take a while to put it together. Only because the nuts are very hard to screw on. So have it electric tool on hand I am sitting in it as I write this review it’s great.

I like the chair, but didn’t realize it would require help and 2 hours to assemble. I don’t think it was mentioned on TV, and it’s not mentioned on the website.

Thank you Tony- Inversion Recliner with Massage & Heat at an affordable price? I was skeptical knowing most chairs cost $1000s of dollars but glad I took the chance. I am disabled unable to walk or stand and in pain 24/7- was able to put the 75 lb chair together with the tools provided in an hour. The instructions were well written and clear although I had to ‘study’ some of the diagrams to make sure I didn’t make a mistake. Comfort is great – massage & heat powerful! Remote offers many levels!
