This is an important question because the difference between ‘made to measure’ and ‘built to fit’ is huge. And – perhaps just as important – ‘built to fit’ is a closer to ‘set size’ than you might think.
The best way to describe this is with an analogy with buying clothes – say trousers.
Set size would be like buying a pair of small, medium or large trousers. The larger sizes will be both wider and longer, this is the same for set size chairs.
With built to fit you have a little bit more control, so back to the trousers analogy, you’d have a waist measurement and a leg measurement – so you don’t have to suffer with trousers that are too long because you need a bigger size. But the waist and leg measurements come in fixed sizes – the trousers are still ‘off the peg’. And so it is with built to fit chairs, you can choose a lower seat height, for example, but you can only choose between a few different dimensions that are fixed within a set ratio between the two.
Essentially, if your ‘built to fit’ chair has a size name attached to it, you’re being sold an off the peg chair dressed up a bit.
Made to measure is more like having a pair of trousers made for you by a Savile Row tailor – they will fit you perfectly because they will have been made to exactly your measurements: waist, inner leg, high hip, low hip, waist to low hip… you get the idea.
A made to measure chair is constructed to five specific measurements:
- Seat height
- Seat depth
- Set width
- Back height
- Arm height
These are the five crucial measurements to build you a chair that fits you properly and they can be any combination of sizes. This results in the most comfortable chair possible and reduces the possibility of pressure sores and ulcers.
Of course, you’ll pay more for a tailored pair of trousers than an off the peg pair, and this is why made to measure chairs are more costly that those than are set size. What might surprise you is that you probably won’t pay much more for a made to measure chair than a built to fit one.
