You'll have to visit an Israeli IKEA store to see the items in person, and you can only buy ready-made items through Milbat. However, you don't even have to buy anything if you have a 3D printer and some filament -- the designs are available to make for free. You can even ask for customizations in case the designs don't fit your third-party furniture. This is less about profit and more about encouraging furniture makers to consider accessibility as an important feature, whether it's built into a given design or available as an extra.
