There are two types of patio umbrellas. The first one is a freestanding umbrella. These freestanding umbrellas are best for those who have bigger patio space. They can be moved around according to one's needs. The other version is fixed on the middle of a table. These are somewhat restricted to one place.

The size that you choose really depends on how much shade you need. And how much shade you need may be influenced by the season and latitude of your location. Typically, the size of the patio umbrella ranges between 6 and 11 feet in diameter.

As well, other considerations include; a sturdy design, strength of pole, the material of the base (stainless steel or aluminum) and hub (nylon or plastic), durable fabric, ease of storage, opening and closing.

You can find poles in hardwood, teak, mahogany and ash. If you prefer the non wood variety, go for chrome steel or anodized aluminum.

In terms of fabric, patio umbrellas can come in acrylic, vinyl, polyester and synthetic thatch. The umbrella is also coated with chemical that resists stain, sun rays, rain and snow. When you are using one, you want to spray on a coating once a year.

These patio umbrellas also come with their own set of accessories. They are replaceable canvas, lights, torches, fabric cleaners and carry-bags. To create desired moods are the main purpose of the lights. There are also remote controlled umbrellas for those who go for style.

Last but not least, choose a base for the umbrella that suits its size.

Apart from patio umbrella, there are also market umbrella. One can tell that an umbrella is a market umbrella with the absence if hanging valances around the umbrella. The frame is sturdier than that of a patio umbrella. There is also a crown of fabric on top of the umbrella, which is a wind vent. This actually allows the wind to escape from underneath the umbrella. Market umbrellas are most suitable for tables.

Both patio and market umbrellas are good not only for keeping out the elements but also as part of your deck furniture decor. Purchase each, ready-made or custom made as per your deck furnishings design.

An offset umbrella is also worth considering too. There are some with tilting feature. An offset umbrella's pole is located at the side of the table. This can be quite convenient as it is out of the way.

For the offset umbrella that can tilt; you can effectively tilt the umbrella to an angle that will give better protection from the sun. This is true as the sun shifts its position throughout the day so there is a need to adjust to this. However, these tilting umbrellas do not usually come with wooden poles.

There are a few things to consider before purchasing your umbrellas online. The warranty, how much time the delivery will take and will there be coverage for damages during delivery. There are sellers who can offer free shipping.

Don't forget the health aspects of staying outdoor. Don't let this stop you from creating a stylish outdoor space either. Have a pleasant outdoor relaxation time and keep your good health too with patio umbrellas or market umbrellas.
