If you have bunk beds for your kids, having stairs that go to the top bunk is a lot safer than using a ladder. They’re easier to navigate and there’s far less danger of falling off stairs than off a ladder. It’s a job you can undertake yourself, although it will take some detailed measuring and cutting. With patience and preparation, you’ll be able to accomplish it reasonably easily.

 

Step 1 - Taking Measurements

The stairs will go at the bottom of the bunk bed, rising from the floor to the top bunk. To take the measurements, begin by measuring diagonally from the top of the railing on the wall side of the upper bunk to the bottom of the foot on the lower bunk.

Now, take the two pieces of wood that are 2 inches by 16 inches by 8 feet in size. Put one on top of the other so they match up exactly. From one corner, measure 3 inches each way along each side and mark off the triangle the points make. From the point you’ve marked on the short side, measure up the distance you’ve previously measured on the bunk beds. Mark the spot with a pencil. Now repeat the process, measuring up from the 3 inch point on the long side of the wood. Join the two new marks together, extending the line across the plank.

Step 2 - Cutting

Using your saw, first cut the triangle on both pieces of wood then cut across at the other end where you’ve measured. These two pieces will be the sides of your stairs. Turn them so they mirror each other.

Step 3 - Steps

Taking the triangle as your base, measure up 12 inches on each side, once from the front of the triangle and once from the back. Using a straight edge, draw a line across the plank joining the mark. From there, measure up 14 inches from the line and mark and create another line. Repeat this until you are close to the top. Now do this on the other plank. These are where the stairs for your bunk beds will fit.

To fit the stairs, hold the lower edge of each stair piece (the wood that is 2 inches by 16 inches by 2 feet in size) against the mark. Screw in from the outside of the stair side, using your level to ensure the stair piece is straight. Repeat on the other stair side until the stairs are secure. Use 4 screws on each side for each stair.

Step 4 - Attaching the Stairs

Turn the stairs so they are upright and against the foot on the bunk beds. Slide into position. Drill holes through the stair side and the bed frame and hold the stairs securely in place.

Position one piece of the 2 inch by 4 inch by 30 inch wood upright against the stair side so that 24 inches of the wood reaches above the side. Drill and bolt in place, ensuring the wood is straight and upright with the level.

Repeat with the other piece of wood the same size further up the side. Place the remaining piece of wood inside these, 2 feet up from the side. Bolt in place so the angle is the same as the stair side. This will be the side rail for the stairs for your bunk bed.
