Desk Chair Parts

Desk chair parts play a vital role in the comfort-level and usability of the chair. These come under technical specifications of a desk chair. Some examples of these are pipes, metal and plastic joints, pipe rests, rotating cross- joints and rubber end caps. Some chairs are designed with old and physically disabled people in mind. For such people, various additional parts can be installed.

A caster is an important part of a chair. It is a tiny wheel on a swivel, attached under a portion of the furniture, to make it effortless to move. It comes in sizes of 50 mm, 65 mm and 75 mm. The wheel diameter has a major influence on the performance of a caster. Various types of casters are available in market such as chair and furniture casters, total locking casters, stainless casters and nickel-plated casters. Pneumatic and stem mount casters and plate mount casters are also available.

The plastic parts of a chair are the seat covers, back covers, armrests, bases, and telescope gas covers. Metal parts comprise of mechanisms, gas lifts, brackets, fittings and hinges. There are various ANSI or American National Standards Institute standards for bases and casters. These casters are used for hard flooring and mats. They are intended for repeated movement on an executive or office chair.

An elastic rubber wheel cares for tough floor surfaces such as hardwood, ceramic tiles and synthetic mats. Precision sealed ball bearing in a wheel offers easy rolling and not at all need repairs. A special mechanism on a wheel improves the ability to swivel or adjust direction. A grip ring socket is used for mounting casters on wood furniture. The choice of suitable desk chair parts and repair parts is not easy. There are loads of choices available in sizes, colors and shapes.

How to Choose a Mobility Scooter

Introduction

For many people with limited mobility a powered scooter is a good alternative to a wheelchair. Many people prefer a scooter to a wheel chair as they are more attractive visually, are lighter, more compact and have better maneuverability. We will look at mobility scooter features, their value as mobility aids and other information to consider when choosing a mobility scooter.

Construction

An electric mobility scooter is composed of a wheeled platform containing the drive unit and batteries, with controls and hand rests towards the front and a seat at the rear. For rugged terrains and hills a rear wheel drive unit would be preferred as they have better traction than a front wheel drive model. The platform or drive unit is usually made from steel, aluminium or fiberglass or sometimes a composite is used. There may be a cover over the drive head and dashboard instruments. When considering the scooter to purchase the size, ground clearance and turning radius should all be considered as these relate directly to the maneuverability.

Comfort and Safety

To ensure the needs of the rider are met the base unit dimensions and construction should be carefully considered. The feet must be comfortably accommodated and the controls easy to use and comfortably within reach. This is vitally important for a very tall or short riders. Many scooters have adjustable seats and arm rests and some have various base dimensions or extra footrests for longer legs or for those who wear leg braces.

Safety Features

Stability of the base unit on inclines and sharp turns is important. Many scooters have anti-tip mechanisms on the wheels for stability during maneuvers of these kinds so we advise you to check that the scooter your are considering has these mechanisms.

Drive Train

Front Wheel Drive Models

Manufactured primarily for indoor use, front-wheel drive units are less powerful than rear wheel drive models but usually smaller and more maneuverable. They are only recommended for smooth floors or pavements and may have difficulty coping with curbs. Because they are smaller than rear wheel drive units they are more easily transported and more likely to fit into a wheelchair lift.

Rear Wheel Drive Models

With more powerful motors and longer range, rear wheel scooters are much better in rougher terrain or uneven pavements. They are larger than front wheel drive models and less maneuverable. More suited to outdoor use they have higher speeds but are less easily transported and less likely to fit into wheelchair lifts.

Brakes

Rear wheel drive models have an electronic braking system that is engaged when pressure is released from the controls. The brakes therefore will always be engaged when the unit is not being driven forwards or in reverse. In order to be able to move the scooter manually a brake release lever is provided. Many scooters have disc brakes in combination with, or instead of, the electronic system.

In contrast front wheel drive models do not usually have an electronic system but have a parking brake that is manually applied to the rear wheel.

Batteries

The electric power system is either 12 or 24 volts supplied by one or two batteries. Rear wheel drive systems are generally 24 volts while the front wheel systems 12 volts. Add on units may be available to increase the range, but not the speed, of the scooter. The batteries are not interchangeable with auto batteries as their job is for sustained provision of power rather than a short starting burst as required by an auto battery. Their lifetime is between twelve and eighteen months and they are designed for regular charge and discharge. Batteries may be of the lead acid type or the gel cell type and are usually purchased as an extra. Battery chargers, whether integral or separate units are usually included in the purchase price. Ensure that the correct type of battery is purchased as chargers may be specific to the type of battery (lead acid or gel) although some chargers are dual purpose. Both independent and integral chargers have their advantages and disadvantages. An integral charger is convenient but if it goes wrong the whole scooter must be returned for repair. An independent charger is bulkier to move around but more easily replaced if needed.

Wheels and Tires

maneuverability of the scooter depends to a large extent on the wheel and tire size. Small tires on front-wheel drive models increase maneuverability but decrease traction so rear wheel drive scooters generally have bigger tires for better grip on uneven terrain. Pneumatic tires, foam filled tires and solid tires are available. Pneumatic tires, as on most autos, are better for comfort but need maintenance and replacing when worn. Foam filled tires cannot be deflated and are almost maintenance free. However they are less comfortable to ride and more expensive. Solid tires are only suitable for indoor use, are maintenance free but considerably less comfortable.

Seating

The seating should be considered carefully when choosing a mobility scooter. Arm and head rests may be included and seat padding will play a big factor in comfort especially when the scooter is ridden for a long time. Fabric covering is much more comfortable than vinyl but more expensive and harder to clean. Powered seats are a big help in mounting and dismounting but add to the cost. Powered seats may also allow elevation but again this feature will increase both the initial cost and the drain on the batteries. Seats that can be adjusted will be necessary if the rider is taller or shorter than average. Check to see if armrests can be flipped up for mounting.

Controls

Thumb levers are the most common types of controls but joysticks and loop handles are also used. A joystick attached to the armrest may be more suitable for someone with limited thumb mobility or strength.

Accessories

Other accessories that may be important to an individuals needs include oxygen transporters, crutch holders and front or rear baskets. Horns, lights and canopies are also optional in many cases.

Conclusion

Matching the needs of the rider with the features offered by the manufacturer is the most important consideration. Where will the scooter be used? Is the scooter the right dimensions and can it be adjusted for the size of the rider? Will thumb levers or a joystick be more suitable? Consideration to these questions will ensure that the mobility scooter chosen is the best one for the individual rider.

Sheepskin Car Covers - What Are the Cheapest Seat Car Covers

So you are looking for some Sheepskin Seat Covers for your new or used vehicle. You already know that using seat covers will do many positive things for your specific vehicle. Here is a list of just a few positive things you can count on. Seat sheepskin covers will do the following for your vehicle.

• Lengthens the life of your seats


• Helps your vehicle keep its value when its comes time to sell or trade in.


• Gives you piece of mind when it comes to something getting spilled on your seats.

When you start looking at Sheepskin leather for your new seat covers, you will most likely run into some terms that will more than likely confuse you more than anything. Here are some of these terms and what they mean. Remember these definitions are used a little different depending on the dealer, but overall these will be correct.

1. Ready Made - These covers are pre made covers that will fit a lot of makes and models of cars. These do not need to be mixed up with the covers sold in the department stores. Ready made sheepskin covers sold through most dealers are actually made to fit the way they are supposed to.

2. Tailor Made - Tailor Made seat covers are especially made to the exact dimensions of your vehicle. Vehicles that have seat belts made into the seats will have to have tailor made seat covers. Many cars have seats that have odd dimensions and shapes that no ready or pre made covers will fit. SO they have to be tailor made.

3. Double Cap - Double cap sheepskin covers are all sheepskin. This means they have sheepskin on the front, bottom, sides as well as the back of the seats. These are the most expensive and the hardest to install because they do not stretch a whole lot.

4. All Sheepskin - These are the exact same thing as a Double Cap. Its just a more simple term and makes more sense to someone that doesn't know anything about sheepskin covers.

5. Super Fit - Super Fit covers basically have Sheepskin on the front & bottom of the seat where your butt and back rest. They usually have a stretchable acrylic material that has a matching fleece that normally matches the color of the sheepskin very closely on the sides and back of the seat. These are easier to install because of the stretchiness of the acrylic.

6. Deluxe Super Fit - These are super fit covers that are made with the best quality sheepskin offered. These covers are the most expensive ready made covers because of the quality of sheepskin used.

7. Mosaic - Mosaic usually means a pattern of different colors, but most of the time with Sheepskin it just means the seats are made in a pattern of small diamonds or squares. They are normally the same color. Mosaic is actually made up of a lot of small left over pieces instead of one big piece of sheepskin.

8. Mosaic Super fit - These are covers made in a mosaic pattern that has the acrylic on the sides and back of the seats. Mosaic covers are usually cheaper because the pieces used are made up of smaller pieces that can't be used on anything else.

9. Tailor Made Mosaic - These are tailor made covers that are made from the smaller pieces in a diamond or square pattern. Since these are tailor made they are usually all sheepskin or double cap. Sheepskin on front, bottom, back & sides. This is something one company may do differently than another so it is wise to ask if they are all sheepskin or super fit.

10. Standard - Standard usually has a shorter fleece than the other options available. The standard sheepskin is considered a lower quality because of the shorter fleece. My personal opinion is they are of the same quality its just that the fleece is shorter & many people actually prefer the shorter fleece.

Now that you know what these terms mean. It's time to put it all together so you can get the most for your money. Sheepskin is a very durable leather and the fleece has some amazing properties. Sheepskin is warm in the winter and is cool in the summer. What ever decision you make when picking out what kind of sheepskin covers to purchase for your vehicle will not be a bad one. Here is a list of things you need to do before ordering your Sheepskin Seat Covers from any dealer.

• Decide what kind of density of sheepskin fleece you want. Remember Deluxe means best or thickest fleece. Mosaic is the same thickness but made up of smaller pieces. Standard has a shorter fleece than the others. Deluxe is most expensive - Standard is in the middle & Mosaic is usually the cheapest.


• Decide if you want to have all sheepskin or super fit. Do you have to have sheepskin on the sides and back of the seats? It will save you a lot of money if you choose the super fit.


• Find out if you need tailor made covers? Don't let any dealer fool you into getting tailor made covers. Make sure you ask why do you have to have tailor made? If you have integrated seat belts into your seats or built in armrest you will always have to have tailor made. If you have odd shaped seats or really thick seats then you may have to have them tailor made also.

In my opinion if you want the best price go with the Mosaic super fit. Even if they have to tailor make them it will still be affordable. On the plus side the mosaic has a pattern that usually looks really nice & remember the mosaic is made up of the best quality sheepskin. These are my personal favorite for quality and price (mosaics are actually just the left over pieces). If you would like a shorter fleece then definitely go with the standard super fit, If they can fit your vehicle with it.

Most of the time you can't get a bench seat done with the standard, but if it bucket seats then there shouldn't be a problem. Of course if price isn't a option then go with the all sheepskin seats. These are the best of the best. These are good for show cars where this may count towards more points for your show car. Some people just feel better knowing there sheepskin seats are all sheepskin, but I will not tell you they are my first choice. Because I'm cost conscious and like the most for my money.
