Side stands are the kind you'll generally find on hybrid and mountain bikes. The side stand is generally fixed near the chainset, but can also be attached to the frame's seat stays or chain stays.
For bikes with a heavy load (bags, child seat, basket, etc.) a side stand is perfect. Just remember to check the maximum load that the stand can take. In the case of a heavily laden bike (particularly with a lot of weight at the back), the ideal position for a side stand is at the back on the opposite side to the derailleur.
