Portable chair frames can be constructed of either steel or aluminum and have weights anywhere from 15 lbs. and 45 lbs. depending on the model. All chairs will fold from side to side and some have folding back the make transporting and storage easier. Most chairs have weight capacity of 250 lbs. But the heavy duty models will hold up to about 450 lbs. Of course, a chair which will hold 450 lbs. Will be a much more heavily constructed and will push the weight towards the 45 lb. weight. The most common wheel configuration for portable chairs is four 8\" casters with solid tires. The front two casters will swivel to enable turning. On some models the rear two wheels may be 12\" in diameter instead of 8\" and have air tires insted of solid tires. The larger wheels will give a little bit softer ride and traverse rough terrain a little better. They fold up in interesting ways to collapse to the size of a suitcase when not in use and are usually large enough to cover one or two stairs when extended. It is important to consider their weight and the person who would most often be carrying the ramp and setting it up.

Adding Estradiol to Testosterone in rate model significantly increases prostate carcinogenesis in rat model.
