Easier access for people in wheelchairs. Some oversize items may not fit easily on narrow shelves. Uses more energy and costs more than other models. Good for tall people and older people, who don't have to bend over as much. Not so great if you use a lot of ice - then you'll do a lot of stooping.
Fewer models are available, and prices are higher.
For easier access, look for models with slide-out drawers or baskets in the freezer. Similar in space requirements and energy use to a top freezer. Wine coolers, icemakers and refrigerator drawers that blend into cabinetry. Some are designed for outdoor kitchens. Before shopping Measure the space carefully, allowing enough room for door swing and clearance for air circulation.
