Common Chair & Stool Maladies

The last thing medical professionals need is a problem with their office chair or stool. The work of a doctor or nurse is taxing enough. Well-functioning, comfortable medical chairs and stools go a long way in a busy office to improve work flow and efficiency. Here are some common questions practitioners have regarding their chairs and stools.

Q: Why do the wheels on my chair not roll smoothly?

A: Often, sticky wheels are caused by build up on the casters and wheels of rolling chairs. As the wheels roll around the office all day, debris and dirt can accumulate and create an impediment to well-functioning wheels. Simply clean out the wheels and casters to solve the problem.

Q: How often does my office chair need cleaning?

A: To some degree, the answer to this question depends upon the type of medical work you do. If you work in a veterinary clinic, for example, and see animals in your exam room on a daily basis, then your chair may need more frequent cleaning. Generally speaking, a simple wipe down every few months should keep your chairs and stools in great shape.

Q: Why does my chair squeak?

A: Rolling stools and chairs often squeak when two or more moving parts rub against each other. One of the best and easiest solutions is to lubricate the moving parts in your chair with lubricating oil, such as a spray.

Q: Why does my chair lean back far and fast?

A: No one likes the feeling of falling out of a chair. A loose tension setting of the back support is probably to blame. You can fix this by finding the knob under the chair that adjusts this setting, and turning it until you find the tension that feels comfortable to you.

Q: Why won’t my seat hold its height adjustment? It keeps sinking and rising on its own.

On the top of the cylinder there is a little green button that when pressed releases the cylinder so it can be adjusted up and down. There is a bolt in the underside of the seat in the adjustment mechanism that is keeping the button pressed so it isn’t locking into place. To remedy this please follow the steps below.

  1. Carefully remove the cylinder from the underside of the seat. When assembled, the cylinder is pressure fitted into the adjustment control so it may take some “elbow grease” to remove it from the top. (To do this, flip the stool upside down and hold the stool off the ground by the cylinder. With a rubber mallet (or a hammer but be sure to protect the metal of the adjustment control) carefully tap around on the underside of the seat. It may take a little time but the top will fall away from the cylinder.)
  2. Inside the center hole of the adjustment mechanism where the cylinder had been there is a 10mm bolt. With a 10mm socket, turn the bolt CLOCKWISE (half a turn at first) to drive the bolt further into the underside of the seat. This bolt should be out far enough to press the green button when you use the lever to adjust the height, but not so far out that it continually pushes in the green button without using the adjustment lever.
  3. Put the cylinder back into the underside of the seat. Test and repeat if necessary.

Finding The Best Medical Chair or Stool

How to Find the Right Stool or Chair for Your Medical Office

A medical office is an important part of the community. Doctors and other medical professionals take care of patients, suggest health solutions, and contribute to the overall well being of the community. With so much important work to do, it is a great idea to equip those offices with the tools and supplies that facilitate the work flow of your office well. Choosing the right medical chairs and stools can make a big difference in the efficiency and work flow of your office. Here are some things to consider as you choose the right chairs and stools for your practice.


Often in medical offices, practitioners, nurses, and office staff are in and out of different rooms all day. Adjustability of your chairs or stools is essential to ensure a seamless transition from room to room for employees with different body heights and types. Some aspects of the adjustability of a chair that you may want to consider include:

  • Seat height
  • Seat depth
  • Seat angle
  • Seat back position

Not only should chairs and stools be adjustable, they should also be easy to adjust. It shouldn’t take more than a second or two for a doctor or nurse to change the seat so that their attention can then be focused on the patient.


Maneuverability is an important consideration in choosing the right medical chair or stool. It is likely that you will need to move around the exam room to attend to patients, retrieve supplies, etc. Consider rolling stools or chairs to help improve work flow in exam rooms.


Another aspect to think about is the space the chair or stool takes up in the exam room. Some rooms would necessitate a stool with a smaller footprint. Others may be able to accommodate a larger chair. Whether or not your chair should fit under a desk or table is another consideration in your selection process.

The Evolution Of The Microscope

Some take medical microscopes for granted because they are a staple of laboratories and research centers. However, the importance of microscopes in the fields of medicine, physics, and chemistry becomes apparent when you consider their evolution.

From Reading Stones to Eyeglasses

The idea that glass could be used to increase visibility has been around for a very long time. In approximately 1000 A.D., an unknown inventor developed a glass sphere as a vision aid. About 300 years later, an Italian man named Salvino D’Armate took this idea to the next level by creating wearable eyeglasses.

Unlocking the Power of Multiple Lenses 

The predecessor to modern-day microscopes was developed in 1590 by a Dutch father-and-son team of eyeglass makers, Zaccharias and Hans Janssen. They discovered that when they placed multiple lenses in a tube, their ability to enlarge objects increased greatly. This technology became the basis of both microscopes and telescopes.

The First Modern-Day Use of Microscopes

Approximately 70 years later, scientists began to use microscopes to investigate cells in organic matter such as blood and yeast. One of the most famous people to do this was Antonie van Leeuwenhoek, who is considered the first microbiologist and is known as the Father of Microbiology. Leeuwenhoek also created new ways of refining microscope lenses.

Microscopes in the 20th Century

Microscopes enjoyed substantial technological advancements during the 20th century. These included the development of several new types of microscopes:

  • The ultramicroscope – provided the ability to study tiny particles
  • The phase-contrast microscope – allowed scientists to study living cells and cell division
  • The electron microscope – allowed observation of matter as small as an atom’s diameter
  • The scanning tunneling microscope – granted ability to view objects in three dimensions at an atomic level
  • The foldscope – a marvel in scientific development, the foldscope is a print-and-fold microscope that can be made from a sheet of paper and weighs less than two nickles but can magnify over 2,000X.

It is clear from even this brief history that microscopes are not only valuable pieces of medical equipment, but that they have also played a key role in the overall advancement of science. Source Medical Equipment is proud to contribute to this tradition by offering a variety of top-quality microscopes that provide scientists and students the tools they need to make the next big scientific discovery.

Use Office Olympics to Build Morale

Holding an Office Olympics can be a great way for employers to boost productivity, as it both breaks the monotony of the work cycle and fosters positive relationships between co-workers. Here are five easy events that you can create with common products like office chairs, paper, and tape.

1. Desk Chair Sprint

You will need a few rolling chairs with swivel wheels for this game. Participants pair off into two-person teams, with one sitting in the chair and the other pushing it. At the buzzer, each team races for the finish line.

2. Spin Doctor

This event requires three people per team. One person sits in a chair with a seat that can revolve a full 360 degrees. The other two spin the chair as fast as they can for 30 seconds. When time is called, the person in the seat must get up and try to run to the finish line, which should be set up a few yards away.

3. Chair Rowing

Participants begin by sitting in rolling chairs in an open area, such as a long hallway. They then push off the ground with both feet, trying to row themselves as far as possible without having their feet touch the ground again.

4. Post-It Stickler

In this team event, contestants are given a stack of sticky notes. They then have a set amount of time to adhere as many of these as possible to a person or a piece of large office furniture, such as an office chair or a tall lamp.

5. Desk-Chair Soccer

Participants follow general soccer rules for this game, with each team trying to get its ball into the opposition’s goal. To make this a little more fun, you can make your own soccer ball out of wadded up paper and tape, like a larger version of those used in trashcan basketball.

Office Olympics games are a fantastic way to build camaraderie among your workers! At Source Medical Equipment we have a variety of rolling chairs and office chairs that work perfectly for any Office Olympic sport!

Chairs in Ancient Cultures

Chairs, the way we know them today, with four legs, armrests, and a back, date all the way back to Ancient Egypt. One of the marks of a civilized person was one who sat in a seat that elevated the body away from the cold, damp, and dirty floor. In fact, places to sit were a way for humans to distinguish themselves from the animal world. Used as an emblem of authority for thousands of years, the chair represented state and dignity rather than just an ordinary place to sit.

Ancient Egypt

gold chair

Some of the earliest examples of chairs today were found in Egyptian tombs, including the famous seat of Tutankhamun and the chair of Hetepheres, an Egyptian Queen of the 4th Dynasty. Chairs were reserved for the rich and powerful as they were made of ebony and ivory or of carved wood that was then embellished with costly materials. However, there is hieroglyphic evidence that suggest that the chair was used by all groups of society, though not in the way that is it casually used today.

Chairs In China

Up until the twelfth century, the predominant way of sitting in Chinese culture and neighboring countries was that of the seiza and lotus position on sitting mats or on the floor. Following the Tang Dynasty, chairs became widespread in China. Chairs are rumored to have been brought to China by two different means: Nestorian missionaries and from India as a form of Buddhist monastic furniture.

ren chairChairs of the Renaissance

The Renaissance can be attributed to the ceasing of the chair as a privileged item. Soon following this time period, the authority and high-class qualities associated with chairs faded and they quickly became an object of general use. The materials used to fashion and manufacture chairs became less valuable, as chairs began being made from woods like walnut and oak, as well as fabrics like velvet and silk, rather than more costly trimmings.

Modern Chairs

Chairs today, as you will find throughout our site, use advanced technology to create increasingly comfortable and functional designs. Since we spend a lot of our lives sitting, ergonomically sound chairs have become a popular item used in many workplaces, including doctor’s offices and laboratories.

How Does a Scale Work?

How Does a Scale Actually Measure Weight?

Whether calculating your weight loss or gain, checking a child’s growth at a doctor’s office, or estimating the cost of this week’s produce bill, many people tend to take for granted how often scales are used in their daily lives. Scales serve a wide range of functions, and are essential to today’s healthy daily living.

While there are many different types of scales to choose from today, the following three scales are some of the most common:

  • Top Loading Scales
  • Mechanical Scales
  • Digital Scales

You may be surprised to learn how these scales work, and how they accurately measure a range of weights and objects.

Spring Scales

Spring scales are some of the most common weight measuring devices used today. Like the produce scales you see at the grocery store, top loading spring scales display the force an object has due to gravity by using a system of springs and mechanical levers. These are some of the simplest scales to understand, and make up the building blocks of most scales that are more complex.

Mechanical Scale

Perhaps the most common mechanical scales are the medical scales you see at the doctor’s office when you go in for your regular check-up. Using a system of balances and reference weights, the weight of an object (or person) is calculated and displayed by matching the weight of the reference point with the weight on the other end of the scale. These scales are often used in laboratories and medical facilities.

Digital Scale

One surprising fact rarely known to the public is that digital scales differ from mechanical scales only in how they display the weight measurement.  The analog data is simply converted to a digital readout. Many medical facilities are updating to digital weighing equipment for ease, convenience, and in some cases, better accuracy.

As you come to understand how a scale works, you will be better prepared to make the best choice from our wide variety of scales at Source Medical Equipment.

The Evolution of the Office Chair

Although the chair started out as an article of furniture for only the most dignified persons and royalty in different societies, it has slowly evolved to become what it is today: a common piece of furniture in homes, offices, and other public places. Chairs were once symbols of power and status. Thrones and other chairs of rank were common in many cultures including Egyptian, Greek, Mexican, and English. It wasn’t until the 16th century that chairs began to become more commonplace objects used for everyday comfort and work. The chair has in fact evolved over time, becoming more suited to its function, more comfortable, and even more attractive in some cases.

As you look at the evolution of the chair from century to century, it is important to note the increasing need for and focus on the office chair today. From the rolling chair to the ergonomic support chair, it is not hard to see why today’s chair selections are essential in creating the efficient, productive, and health-conscious environments that are sought after in the modern workplace.

The Creation of the Rolling Office Chair

Some speculate that Charles Darwin was the first to add wheels to the bottom of his office chair in order to get around his laboratory more quickly and efficiently. Whether or not Darwin was the first to come up with this clever solution to a common office problem, workers everywhere can appreciate the ease and ingenuity of today’s rolling chair.

The Introduction of Ergonomic Comfort and Support

The introduction of the ergonomic chair was also quickly welcomed in the workplace. Designed with the health and comfort of the body in mind, the ergonomic support chair turned its focus to the back and core of the body rather than rear end. Completely relaxing the shoulders and elbows with proper posture, ergonomic chairs have impacted the health consciousness of the workplace forever.

To take advantage of the most up-to-date office chairs on the marketplace today, check out the great variety we have to offer at Source Medical Equipment.

Choosing the Right Chair

Few people actually realize the impact that their office chairs can have on their overall health. The wrong chair can encourage poor posture, provide little to no lumbar support, and place extra stress on the spine, shoulders, and elbows. Thus, choosing the right kind of chair becomes vital given the amount of time that you’ll be spending in it. The trouble is that you probably don’t have access to an ergonomist who can explain what you should be looking for when selecting your office furniture.

What Factors to Consider

Yet no one is truly without access to information when it comes to choosing quality office furniture. At Source Medical Equipment, we’re happy to provide any information you need when researching your next office chair purchase. When customers ask us about what they should consider when selecting a new office chair or stool, we highlight the following factors:

  • Height: A chair should allow you to sit fully upright with your knees bent at a 90° angle when your feet are on the floor. This allows for uniform weight distribution.
  • Depth: A seat that’s too small or too big won’t provide you with the necessary support to your knees and thighs. The ideal seat will offer about an inch and a half of space between the edge of the chair and the back of the knee. This distance is the equivalent to the length of about two or three fingers.
  • Width: The distance between armrests shouldn’t be so wide that you can’t comfortably rest your arms while sitting.
  • Arm and backrests: Armrests should be at resting elbow height when sitting upright to allow for support when typing or writing. The backrest should contour to the natural curvature of your spine, forming an “S” shape.

While the wrong chair may not cause chronic back and joint pain overnight, its continued use can take a heavy toll on you and your body. Choosing the right type of chair up front allows you to avoid any potential posture problems altogether. We offer a wide variety of chairs, many of them customizable, so that you can find the perfect fit for you.

Considering A Sit-Stand Chair

For many of us, a typical day at work involves having to stand up and sit back down countless times. While this routine may seem perfectly normal, the truth is that over time, constant standing and sitting can take quite a toll on our bodies. Some of the consequences include chronic back, knee, and ankle pain or the development of overall poor posture, which can lead to joint deterioration over time.

The Anatomy of a Sit-Stand Chair

Yet there’s hope for those required to constantly jump to their feet during the workday. A sit-stand meets you half way. It sits higher than a typical chair, which also makes it ideal for workstations or tabletops that sit high up off of the ground. We can customize any of our Perch Sit Stand chairs to meet your specific needs. Some of the various options available to you include:

  • Base: If your job requires that you be mobile while sitting, you can choose a sit stand with a wheel base, allowing you to quickly glide around your office or workstation. If you work on a drafting table or a high desk, then you may want to consider a standard base that will prevent you from tipping or sliding.
  • Legs: A single leg perch is ideal for a rotating or swiveling base, and can even be adjusted to allow you to be in more of a standing position. However, if you anticipate sitting in the stool uninterrupted for long periods of time, you may prefer the stability that multiple stool legs will provide.
  • Seat: Most sit stands come equipped with comfortable padding and allow for the adjustment of the seat angle. Some also offer a rotating base that allows for greater freedom of movement. For those wanting extra lumbar support, consider a chair or stool equipped with a backrest.

We at Source Medical Equipment offer a wide variety of sit-stand chairs. Depending on the type of work that you do, we can find the ideal chair to help safeguard you from any of the potential consequences of constant standing and sitting.
