"Wooden Loft Ladder Shop" and "The Loft Ladder" are both places where you can select and purchase a loft ladder. The UK based "Wooden Loft Ladder Shop" is my preferred choice.

A wooden ladder usually have rungs made from wooden dowels with tapered ends. An aluminium ladder would have extruded aluminium rungs.

Depending on whether or not a wooden ladder is properly stored and treated dictates how long the lifespan will be for it. Most wooden ladders are expected to last a lifetime, so the average is predicated on length of ownership.

Prices for a loft ladder actually vary a lot. If you were looking for a cheaper one, they run around 90 to 100 dollars. More expensive ones will go up to around 200 dollars.
