Climbing up and down stairs can be tiring for old people and not all houses and bungalows are equipped with elevators. Take a look at this Curved Stair Lift by French company ThyssenKrupp Monolift which provides an innovative answer to this problem. (Thanks, DigsDigs)
Although home stair lifts aren't very popular, they can be very useful for those people who have a house with several floors. Chair lift is a more economical solution than elevator lift, but also can make a life very comfortable. They could become practical and even a necessary appliance for old people who can't move between floors without a help. This curved stair lift is very easy to install and can perfectly fit into narrow stairs.
