Remember when flat, uncomfortable inclining lifts were installed in dank, musty homes? French company ThyssenKrupp Monolift ThyssenKrupp Monolift have devised the clean, white, cyberprep-looking lift that looks like it can be infused seamlessly into many home motifs. Easy to install and definitely more economical than installing an elevator, the chair is a simple and accommodating solution for those who've saved all their lives for the 4-story dream home and find the stairs a little tough on the knees.
