Looking for a fun and functional furniture project for a teenager's room? This DIY wardrobe trunk is a large wooden chest designed as a closet, mounted on swivel casters for easy moving. It can stay open for convenient use, with a fifth wheel for extra stability. Here's how to build your own rolling wardrobe trunk.
Why Build a DIY Wardrobe Trunk?

For a teenager's room, you want furniture that's playful, colorful, and practical. This trunk is sized for their height, making it easy to use and encouraging them to keep their space tidy. It's a simple, customizable project—adjust the dimensions, colors, and finishes to match their personality. You can build it from OSB, plywood, or MDF panels, then cover it completely for a polished look. This method simplifies construction: just fasten pieces with nails or screws, countersink them, fill the holes with putty, and apply a covering paint.
Materials and Preparation
Before you start, gather your materials. You'll need wood panels, screws, wood glue, a saw, sandpaper, paint, and home improvement tools like a drill and measuring tape. For the casters, check out our home improvement collection for heavy-duty swivel wheels.
Building the Box with a Lid
Start by assembling the box: join the panels to form a closed rectangular shape. To create the lid, make a precise, straight cut about 100 mm from what will be the front side of the trunk. Use a guide to ensure the cut is clean and parallel—this is key for a professional finish. For cutting tools, browse our home improvement supplies for saws and cutting guides.
Adding the Casters
Attach four swivel casters to the bottom corners for easy movement. Install a fifth caster near the front edge to provide stability when the lid is open. This prevents tipping and makes the trunk safer for daily use. Find durable swivel casters at GrandGoldman.com.
Completing the Interior
Inside, add a hanging rod for clothes and shelves for folded items. Use lightweight materials to keep the trunk mobile. For storage solutions, consider storage benches or shelving units for inspiration. You can also line the interior with fabric for a soft touch.
Finishing Touches
Sand all surfaces smooth, then apply a primer and paint. Use bright colors or patterns to match the room decor. For paint and finishes, explore our home improvement collection. Add decorative hardware like handles or hinges from our home improvement selection.
Customization Ideas
- Paint the trunk with chalkboard paint for a writable surface.
- Add a cushion on top for extra seating—check our outdoor patio furniture for cushion options.
- Install a mirror on the inside lid—browse mirrors for ideas.
- Use it as a window seat with curtains—see our curtains collection.
- Add a rug underneath to define the space—shop rugs.
