My partner used to work as a kitchen designer for a super high-end German cabinet company, and we bought Ikea cabinets for our kitchen remodel. The wall cabinets all hang on a rail. We put them together and installed them ourselves. The base cabinets come with legs that have twist-to-level feet, so there’s no shimming involved. The hardware is still soft-close, and the cabinets and doors/drawer fronts are holding up great. We used dark wood veneer slab fronts on the base cabinets, and white lacquered MDF slab fronts on the uppers (I can’t remember the name of either). We have 14 cabinets total – I put them together by myself in 1 day while my partner was demo-ing the old cabinets, then we installed them together the next day. You install the rail by screwing it into studs and making sure it is level. Honestly, a new kitchen in a weekend. Then each cabinet that hangs on it is automatically level – genius. They have been in for 3 1/2 years, and we haven’t run into a single issue.
