Lifetime Products, National Public Seating, and Correll all manufacture adjustable tables. These different manufacturers use a couple of different design options. These different design options provide uses for different needs. We will explore these options here.

Lifetime Products and National Public Seating

Lifetime Products has a traditional push-pin design. Simply engage the pin triggers on either side of the table legs and either pull up or push down on the table top to change the leg lengths. When the table-top height can be locked in, the push pins will pop out in a locked mechanism. National Public Seating uses a similar mechanism. Simply engage the push pins and slide the legs longer or shorter as needed.

Correll

Correll, inc. uses a screw-locking mechanism to change the height of many of their adjustable tables. This design is a little more cumbersome than simple push pins; however, their mechanism allows for a larger quantity of height settings. For instance, the Lifetime and National Public Seating design typically provide 3 height settings ranging from 22 inches and 36 inches. The Correll design has 11 settings ranging from 22 inches to 32 inches in 1-inch increments. Thus, both designs have their advantages and disadvantages.
