RATINGS EXPLAINED
Massage Chair Rating System

The system we use to rate the chairs on the site is simple. We take into consideration all of the features of massage chairs on the market and each chair is then compared to this framework.

The current features we rate are:-

Comfort On
Comfort Off
Guarantee
Ease of Use
Back Massage
Seat Massage
Calf Massage
Foot Massage
Arm Massage
Heat
Music
Sensor
Range of Colours

Each of these features are given a rating from 0 to 5 in 0.5 intervals and are considered individually.

Comfort Off
The comfort of the chair when it is not functioning. This is usually easy to judge, a group decision is made. This takes into account the extra comfort from additional cushions that are supplied with the chair.

Comfort On
The comfort of the chair when it is functioning. Again this is easy to judge, a group decision is made. This does not take into account extra cushions as they are usually not designed for use when the chair is functioning.

Guarantee
This is simple. Usually each star indicates the length of time in years for which the guarantee lasts. One star = 1 year, 5 stars = 5 years. On the rare occasion a chair may gain an additional half star if the guarantee offers something that could be considered above average.

Ease of Use
Massage chairs can support a wide range of features. The ease of use is rated directly to how accessible these features are and how easy it would be to just jump in the chair and get exactly what you want.

Back Massage
The primary function of any massage chair is to give a half decent back massage. This is judged by taking to account back massage area and depth. Some chairs do well to cover all areas of the back and shoulders but fair to deliver strength and depth. Last of all we take into the account the ability to customise these aspects either manually or automatically.

Seat Massage
Seat massage is sometimes neglected or omitted completely. However, most massage chairs have some form of seat massage. This simply rates the variation of features a chair has in the seat area. This is rated from 0 (no seat massage) to 5 (pretty much crammed full with massage equipment).

Calf Massage
Yet another neglected area. This is usually neglected due to design constrains. The most common forms of calf massage range between vibration (lowest), paddles (average) and airbags (currently considered the best). Speed adjustments are also taken into account but the scoring is mostly down to the technology behind it and the area it covers.

Foot Massage
Most massage chairs up until a few years ago completely lacked a foot massage system. It is only until recently that Inada, Sterling and Sanyo have been including a full body massage system. Some chairs do not strictly have a foot massager but you will see scores for some chairs that don't. The reason for this is that some chairs enable the calf massager to be used as a foot massager as well.

Arm Massage
This is the latest addition to massage chairs, another step in the direction of a 100% full body massage chair. Most of the older chairs on the market are loosing score here since the current range is fairly limited. Arm massage is simply rated by area covered and the pressure it provides to that area.

Heat
Yet another feature most massage chairs lack and therefore loose points on. This is judged upon how powerful the heaters are and how many of them are in the chair.

Music
Music is usually considered a novel feature but some chairs are using built in music systems to massage to the music. This is scored by the features it offers (such as music synchronisation), the quality of sound and formats accepted.

Sensor
Always a tricky subject. Simply judged by its apparent use of measured data and its portrayal of that data to the user. Most chairs score fairly poorly, if at all.

Range of Colours
The range of colours is restricted to the colours offered by dealers and not those of the manufacturer. If there's only one colour it would only score 1 star, 2 colours is 2 stars and so on.

BASE RATING
The base rating is the sum of all the feature scores. The maximum score is 65.

Base Rating to STARS

The stars are calculated as follows:-

6 to 11 = 0.5 Star
12 to 17 = 1 Star
18 to 23 = 1.5 Stars
24 to 29 = 2 Stars
30 to 35 = 2.5 Stars
36 to 41 = 3 Stars
42 to 47 = 3.5 Stars
48 to 53 = 4 Stars
54 to 59 = 4.5 Stars
60 to 65 = 5 Stars

Overall Rating
The overall rating will initially be derived from the base score which the chair receives. However, once the chair is on the site, it is free to be reviewed and rated by other users. The user's reviews give an overall rating based upon their opinion of the chair. This rating directly affects the overall rating of the chair. The rating given is added to the score and a rated value is incremented. These values are used to calculate the final score that the chair has.

Example:

Current Chair Score = 48 (4 Stars)

Chair Rated = 1

Someone reviews the chair and scores it a 5 (60)

Chair Rated = 2

Current Chair Score = 108 (48 + 60)

Final Score = 54 (108 divided by 2)

Stars = 4.5

That's all there is to it.

So if your wandering why a chair is scoring low, simply look at what its features are and see what it doesn't have in comparison to other chairs.
