You may have nothing against shelves in base cabinets – but your back sure does. The use of shelves in base cabinets is poor in ergonomic terms: it makes it very difficult for you to find items since you don’t have an overview of the entire cabinet contents. Shelves in base cabinets is also often the best way to make a kitchen cost less. Whilst the upfront cost is less at the purchase time, the return is very little and over time creates greater issues.
Quite often you will find that you have to bend or stretch to locate items you are looking for. It is not uncommon to find yourself having to remove some of the contents at the front in order to get to the items at the back.
Full extension drawers have the advantage in that they allow you to see and access items in the rear of the cabinet, in contrast to single extension and fixed shelving. This provides you with a complete view of all items and the full extension feature makes them easily accessible.
