What are these cabinets made of MDF or Wood?

This looks very similar to a cabinet that Showplace Wood Products makes, however there are a few differences that suggest otherwise. One caution I would point out -these cabinets MUST have adequate clearance on each side, especially if placed next to an appliance. When used correctly, they are a very nice alternative to the traditional lazy-susan cabinet

Where can i purchase these cabinents?

Good to know! Thanks!

Quite so - a plain old blind corner cabinet with racks that pull out is far more space efficient and just as easy to use.

Lazy Susans aren't appropriate for utensils and smaller items that would be placed in the top drawer.

Otherwise, there are very few solutions for corners that don't waste a whole lot of space - Lazy Susans and this included.

these are corner drawers and are part of Blum's Dynamic Space if you go onto our website you will get a link to Dynamic Space which maximes storage throughout the kitchen!
so as a user I would say most definately these would hold much more and can be adapted with internal orgalines to store various items, from cutlery to small household appliances.
I do hope this has been helpful!

There are only 3 drawers here - not 6.

I seen them special order from LOWES

I love these corner drawers for kitchen cabinets - who carries them in Toronto?

Those are Blum drawer systems. Many cabinet companies use this system as well as custom cabinet makers. This is just one of their many specialty drawers.

We carry Woodharbor and they make those drawers.

Schuler, carried by Lowes, includes those drawers in their line.
