How to make underbed storage drawers
If you need extra storage in a bedroom, making underbed storage drawers with caster wheels allows you to pack away bed linen, winter blankets, clothes, or even shoes, to free up space in your bedroom or closets.
Measure up the available space underneath the bed. Allow for any obstacles that might interfere with pulling the underbed storage drawers in and out, such as wider legs, base support, etc.
Making the storage drawers
To make up your storage drawer/s, take the width of the bed and deduct the thickness of board you will be using:
1520mm - 24mm (2 x 12mm drawer fronts) = 1496mm
For the length of the storage drawers, take the length and allow approximately 30mm (or 10mm between each drawer) for clearance room.
1880mm - 30mm (2 drawers) = 1850mm divide this by 2 = 925mm
The distance between the base of the bed and the floor is 184mm. For this example we have set the height at 150mm for the drawers, which leaves plenty of room for clearance and mounting castors to the drawers.
Calculate the size of the base for the drawers by subtracting the thickness of the sides from the total length.
925mm - 24mm (2 sides) = 902mm
Now we know that we need:
4 of 150 x 825mm - drawer fronts
4 of 150 x 1496mm - drawer sides
2 of 925 x 1496mm - drawer base
Assemble the drawers
Pre-drill 3mm countersunk pilot holes through the drawer fronts into the sides and use 4 x 35mm screws to join together. You can fill in the screw holes once finished with wood filler.
The total height allowance under the bed is 34mm, which includes a 10mm gap at the top of the drawers. This means the base needs to be fitted inside the frame to allow a 21/22mm gap for fitting 45mm castor wheels.
Caster wheels are available in different sizes but the 45mm size is sufficient for mobile storage drawers.
Because we are using 12mm supawood for lightweight and affordable storage drawers, attach the casters to the base using 12mm screws. Also apply a bead of Pattex No More Nails adhesive when securing the wheels to the base.
