Founded by Antonio Calligaris in 1923, this family-run company fuses its roots in wood craftsmanship - the trade that launched their first chairs decades ago. From that artisan birthplace of tradition, style and quality, Calligaris has traveled a long road leading to the use of the most innovative technologies available and expanding to new mediums - from plastics and glass to metal, textiles and leather. Today, the Calligaris range of distinctive collections includes chairs and stools, dining and occasional tables and bedroom-lighting furnishings. Calligaris works with care, passion and creativity to bring into being the best of Italian design, making high quality products at an accessible price. Calligaris products are designed for everyday use with an eye to satisfying the living needs of today's homes.
The company produces intelligent, functional products that are highly affordable, user-friendly and can adapt to differing styles. Designs stem from the analysis of form and function, from experimentation in construction and materials, and by continuous innovation. An ongoing collaboration with leading designers, new talents and an in-house R&D team allows the company to develop solutions answering the distinctive and changing needs of modern home and work spaces. Calligaris holds quality of material and design among the most important of its company values. Their product quality is the result of a careful selection of materials and direct supervision of processes carried out by suppliers. In 2006, Calligaris obtained the prestigious Forest certification from the Forest Stewardship Council. And in 1997 they became one of the first Italian furnishing companies to obtain ISO 9001 quality certification for its entire organization and production system. Beautiful yet practical, original yet affordable and backed by a thorough commitment to quality.

The cylinder on most chairs fails within a few years, typically because the seals are too damaged to maintain pressure. You can buy a replacement cylinder to restore full function to your chair, but this is nearly as expensive as buying a replacement. Try these simple DIY methods instead to fix your chair at one convenient height. Slide the plastic skirt off the cylinder. Most office chairs have a plastic tube over the extendable cylinder. Slide this all the way down or up, until you can see the metal cylinder underneath. Set the chair to the preferred height. You will not be able to adjust the height after this repair, so make sure you have it right.
The seat of the chair should be level with your knees when you are standing. If the chair won't stay up even when no one is on it, lay it on its side. If the plastic skirt covers the cylinder at this height, you will need to remove the skirt first. To do this, turn the chair upside down, push the retaining clip at the base with a screwdriver, and pull off the wheels, then the skirt. Slide the wheels back on. Wrap a hose clamp around the cylinder. Get a ¾" (2 cm) hose clamp (Jubilee Clip) from a hardware store.[2] Loosen the screw on the hose clamp (Jubilee Clip) and pull out the belt end. Wrap the clamp around the metal cylinder, but do not tighten it yet. Improve the grip of the clamp (recommended). The clamp will need to be very tight to hold the chair up. Give the clamp a better surface to grip by wrapping a strip of rubber or a couple layers of duct tape around the cylinder.[3] Do this at the highest visible point on the cylinder, Alternatively, scuff up this area of the cylinder with sandpaper.
If the cylinder looks dirty or greasy, clean this off first. Tighten the clamp as far as possible.The chair should now be unable to slide down past the clamp. The built-in height adjustment will still not work properly. If the chair is at the wrong height, move the clamp higher or lower on the cylinder. If the clamp slides off, fasten it over a strip of rubber to improve the grip, or try the PVC pipe method below. Measure your chair's cylinder. Pull down the plastic skirt cover the extendable, metal cylinder. Estimate the diameter of the cylinder by holding a ruler across it horizontally. Also measure the length of the cylinder when the chair is at the perfect height. You shouldn't need an exact measurement, but you can calculating the diameter from the circumference if you prefer to be precise. Buy a length of PVC pipe. This pipe will fit over the pneumatic cylinder of the chair. It should be about the same size as the cylinder diameter, or slightly larger.
Pipe 1.5 inches (3.8 cm) in diameter works well for most models.[5] Buy enough straight pipe to extend from the wheel base of your chair to the seat, when the chair is at the preferred height. The pipe does not have to be in one piece. It may be easier to work with in smaller pieces, although you can easily cut it yourself at home. One user reports using a tall stack of plastic shower rings instead of PVC pipe. These are even cheaper and easier to install, but they may not be sturdy enough to support your weight. Try at your own risk. Saw through the PVC pipe lengthwise. Secure the pipe in a vise. Use a hacksaw or back saw to cut through the pipe from tip to tip, but only on one side. The end result should be a pipe with a slit in it, not two half-pipes. Wearing a mask or respirator is recommended while cutting PVC to avoid inhaling irritating particles. If you do not have a vise or cutting tools, just leave the pipe intact and remove the chair's wheels so you can slide on the pipe.
In most cases, you can remove the wheel base by pressing a retaining clip on the underside with a screwdriver. Snap the pipe onto the chair cylinder. Pull the chair's plastic skirt up or down to reveal the metal cylinder. Push the slit side of the PVC pipe against the cylinder to snap it around the cylinder. It should now hold the chair in place, preventing it from sliding down. If you're having trouble snapping the pipe on, saw it into shorter pieces and try again. Add more pipe to adjust the height of the chair. You can also buy a replacement pneumatic cylinder for your chair. However, the cylinder often costs nearly as much as a new chair, and can be tedious and difficult to install. You can spend a little more money to buy a "chair saver kit" online instead. This is a collection of clip-on clamps that work the same way as these DIY materials. Do not attempt to secure the chair by drilling into the cylinder and installing a bolt. The cylinder contains pressurized air which may release violently if you puncture the cylinder.
