Erogonomics

Ergonomics is the process of designing or arranging workplaces, products and systems so that they fit the people who use them.

The science of the design of equipment, especially so as to reduce operator fatigue, discomfort and injury. Also called biotechnology, human engineering, human factor engineering.

Ergonomics is the process of designing or arranging workplaces, products and systems so that they fit the people who use them.

Most people have heard of ergonomics and think it is something to do with seating or with the design of car controls and instruments – and it is… but it is so much more. Ergonomics applies to the design of anything that involves people – workspaces, sports and leisure, health and safety.

Ergonomics (or ‘human factors’ as it is referred to in North America) is a branch of science that aims to learn about human abilities and limitations, and then apply this learning to improve people’s interaction with products, systems and environments.

Ergonomics aims to improve workspaces and environments to minimize risk of injury or harm. So as technologies change, so too does the need to ensure that the tools we access for work, rest and play are designed for our body’s requirements.

In the workplace: The total economic cost of work-related injuries and illnesses is estimated to be $60 billion dollars. Recent research has shown that lower back pain is the world’s most common work-related disability – affecting employees from offices, building sites and in the highest risk category, agriculture.

Ergonomics aims to create safe, comfortable and productive workspaces by bringing human abilities and limitations into the design of a workspace, including the individual’s body size, strength, skill, speed, sensory abilities (vision, hearing), and even attitudes.

Ergonomics is a relatively new branch of science which celebrated its 50th anniversary in 1999, but relies on research carried out in many other older, established scientific areas, such as engineering, physiology and psychology.

To achieve best practice design, Ergonomists use the data and techniques of several disciplines:

  • anthropometry: body sizes, shapes; populations and variations
  • biomechanics: muscles, levers, forces, strength
  • environmental physics: noise, light, heat, cold, radiation, vibration body systems: hearing, vision, sensations
  • applied psychology: skill, learning, errors, differences
  • Social psychology: groups, communication, learning, behaviors.
Microsuede

Microsuede is a new, exceptional man-made fabric with wonderful advantages.

Microsuede is a new, exceptional man-made fabric with wonderful advantages. Composed of millions of fine [micro-denier] 100% pure polyester fibers, it has the soft hand of natural suede leather but none of leather’s drawbacks. Microsuede is soft-to-touch, wear-resistant, pet-friendly, stain-proof, easy-care, & inexpensive. The napped surface feels like genuine suede.

Sofa owners love microsuede for its advantages over cotton, wool and leather. Sofa makers prefer microsuede because microsuede is less expensive than leather & much easier to work with. And microsuedes today offer a choice of hundreds of colors and hues.

They say they love microsuede because it is kid and pet-friendly. Microsuede is stain-proof: it’s the easiest of fabrics to keep clean.
They say it is very comfortable to sit and lounge on. Microsuede breathes like cotton. It feels cozy in the winter, and dry & cool in the summer.
They say they like the soft, sensuous feeling of the suede on their skin. Microsuede feels incredibly soft – like brushed, sueded silk.
They say they like the price. Microsuede is luxurious, but now quite affordable.

They say, in summary, that microsuede delivers “an unparalleled combination of luxury, appeal, performance and ease of care.”

The non-woven construction of microsuedes makes them inherently pet-friendly. Common sofa fabrics are woven in loops which trigger cats’ clawing. It’s cats’ instinct. These loops become a handy clawing post for any cat. Microsuedes have no loops. Random pet scratches don’t leave a mark. Stray pet hairs can’t get matted in; a damp sponge wipes them up. In the event of pet “accidents,” microsuedes even resist staining and odor absorption. (Of course a determined pet can scratch or chew almost any material. So supervision is advised.)

Microsuede futon covers are machine washable. Each time you wash your cover, you add to its softness. It will begin to feel like a favorite old shirt. To restore the sensuous nap and soft luster of a microsuede cover, buff the surface lightly with a medium bristle brush.

“Carefree Instructions” is a better way to put it. One of the things futon owners like most, is how easy microsuede covers are to keep looking beautiful–and feeling soft and plush–for years to come.

To restore the soft nap and luster of your microsuede cover, give it a quick once-over with a lint brush.

To pick up dust, softly vacuum the cover. Then pat it gently with a well-wrung damp cloth. Take care not to get your futon mattress wet. When the cover is completely dry, use a lint brush to rejuvenate the fabric’s nap.

Spills and stains usually disappear with a gentle dab of a cloth dampened in lukewarm water. For resistant stains, see below.

Yes, microsuedes are machine-washable. Don’t use bleach. Use cold water, not hot. Line dry, so the cover retains its shape. Don’t tumble dry. Microsuede can be dry-cleaned too.

Use a paper towel to blot up any liquids like wine or cola that spill on your futon cover. Remove mustard, ballpoint pen, red wine, coke, tea, coffee and grape juice simply by using mild soak and lukewarm water. Rub gently in a ciruclar motion with a sponge or soft brush. Pat the area dry after cleaning.

If the spill soaks through the cover, stand up your futon mattress too, so that its cotton batting can dry quickly. If any stain remains on the cover, a simply laundering should remove it. This procedure resolves most stains.

For stains that have already dried, like coffee cup rings, you can often avoid laundering. Gently brush the stained area. Vacuum up any dried residue. If the stain remains, place a few paper towels inside the cover to protect the futon. Then use a well-wrung, clean cloth dampened in lukewarm water. Wipe the stained area outside. Rub very softly. After you’re done, remove the paper towelling. Allow the cover to dry before you sit down again. If the microsuede’s nap looks bedraggled, brush it gently to bring it back.

For oil stains [e.g., street grease, oil, etc.], slip off the cover. Place the outside [stain] face up on the kitchen counter with several paper towels under the stain to protect the counter. Soak and wipe up as much of the oil or grease as possible with paper towels on the outide. Use as many paper towels as necessary. Try not to spread the stain. Next, take two clean rags: a big dry one and a smaller 6″ x 6″ cloth soaked in ethyl [rubbing] alcohol.

Use the alcohol-soaked cloth to pat the stained area from the outside. Then pat off the loosened dirt & oil onto the dry rag. If the stain is resistant, repeat the process again. After the stain is gone, let your cover air-dry fully before putting it back on. If the stain was extensive, cold-water-wash your cover in the washing machine and then line dry it. [Caveat: Never pour any cleaning product directly onto a microsuede fabric. Use ethyl alcohol in a well-ventilated space and avoid contact with open flame.]

First wipe the stain with a cloth soaked in lukewarm water, then rinse by blotting it with clean water. If the stain begins to dissolve, repeat the treatment until the stain is gone. Then let the cover dry thoroughly. If the stain persists, try treating it with ethyl alcohol.

Put several ice cubes in a Ziploc bag & press it firmly on the stain. Once the wax or gum hardens, gently chip it away, and then wipe any residue off on a cloth moistened with ethyl alcohol.

Repeat the treatments described above. Oily stains benefit from a final machine-washing with soap & water.

 

Microsuedes are wonderfully user-friendly: they look good, feel great, and almost any stain can be removed.

Polyurethane (PU) Foam

Open cell flexible polyurethane foam (FPF) is made by mixing polyols, diisocyanates, catalysts, auxiliary blowing agents and other additives and allowing the resulting foam to rise freely.

Open cell flexible polyurethane foam (FPF) is made by mixing polyols, diisocyanates, catalysts, auxiliary blowing agents and other additives and allowing the resulting foam to rise freely. PU Foam comes with various density and stiffness. Similar to human life, foams also have life. Life of foam refers to its stiffness. Over the period of time foam loses its softness and it became firm. For HugSac we use foam which has a life span of 20 years. By the end of 10 years it loses it softness about 10% which is unnoticeable. We use different density foam from 20 kg/m3 to 40kg/m3. Each of our Sac contain 3 to 5 different kinds of foam mix in the right proportion to balance between softness and back support.
