It's just a dresser with a deepish bookcase on top of it.

Stack them, screw them together, anchor them to the rear wall, install hanging rods across the remaining space.

I could do it 30-34" wide from IKEA for about $150-300. Less if I reused one of my short bookcases.

I looked thru the Ikea site but couldn't figure out what to stack on top of what dresser so I gave up. LOL!!!

Drawers are more expensive than you think--the joins are what cost money, so it makes sense when you remember that. (four corners, and the bottom)

And of course, the better the quality of drawer, the easier it is to use. (I don't know how good Easy Closet's drawers are, though!)

There's always this;
a 27.5-inch dresser from Target.

and a 24.5-inch bookshelf from Target

For decades I just used a sturdy bookcase, put baskets on the bottom shelves, and screwed 3 closet rods into the sides: 1 for dresses, 2 on the other side for tops/pants.

Worked just fine....well, until the old WH rusted out and dumped another50 gallons of water into my closet, right after we had a sewer pipe clog which had already sent 'black water' into it!

The problem with using the RTAs from places like Target or Walmart is that the side panels are VERY WEAK. They will probably not hold a closet rod full of clothes; I would not trust it. I have such cabinets, and they are barely functional, not at all sturdy construction.

Check out used furniture places or Craigslist. You need at least 3/4" stock to hold a closet rod securely.

OR, if necessary, clamp and glue a 1x4" board to each side, then screw the closet rod holder(s) onto that.
