Unlike stairlifts, which can only carry one person, elevators are usually designed to carry two people, and some are designed for wheelchair users or up to three people. Residential elevators are also considered more reliable than stairlifts, and while lifts are often a cheaper alternative, stairlifts can be more prone to failure and require frequent repairs and maintenance, which can increase the overall cost of the product. A home elevator can not only be a fashion accessory for any home, but it can also add value to the property, making it a worthwhile investment.
