A mission glider, unlike a hanging swing, functions by use of a gliding track system. This track system is located underneath the glider’s seat, allowing it to slide and swing without being suspended by chains as a traditional porch swing is. There are several advantages to the use of the gliding track system.
First off, porch swing chains are prone to rusting, causing extra work and additional expense in replacing them. The vast majority of gliding track systems, however, are made with rust-proof zinc hardware, making rust much less of an issue.
A second advantage to the glider is that it takes up less space than a hanging swing. If you hope to put some sort of swinging outdoor furniture in your yard or on a deck or patio without a roof, you will have to purchase an additional stand if you wish to hang a suspended swing. With a glider, on the other hand, the swinging mechanism is self-contained, allowing it to take up about the same amount of room as a stationary bench. This difference in size also makes the glider much easier to relocate.
However, gliders are not for everyone. Be sure to weigh the pros and cons of both the glider and the suspended swing before making your final purchase.
