making modular beds

Whether you have a big house or a small house, all you need to do is put the right furniture in the right place and you can easily make the dullest corner of your house look bright and beautiful as ever. Houses with children need to look very attractive and playful so as to keep the child’s attention and keeping him from getting bored. Parents themselves try their best to provide their children with every basic and possible facility for their convenience and comfort.

Making furniture can be a little tricky sometimes, especially if you are new to the wood and tools. Some people nowadays use metal or rod iron beds and furniture because they are lighter in weight. This makes it easier for them to move it around the house to change the settings or to move it while cleaning the house. However, wooden furniture is still the best choice because it is more sustainable, reliable and strong. In addition to all of these features, it also gives an exceptionally appealing look to your house.

This article is about how to make the perfect modular bed for your child keeping in mind his comfort and suitability. Focus on each and every step and try not to overlook any. It is important to have all the materials and tools for accurate measurements to get the desired results.

Materials Needed

The following material will be needed for formulating a bed.

  • 2" x 6" Boards - 13 boards at 96"(8') long. These are used for the main part of the frame. They will make the finished product strong and reliable. You could also use 2" x 4" boards if you want.
  • 1" x 6" Boards - 8 boards at 96" long. These are for the uprights on the head/foot boards. Plus one more board for the mattress supports.
  • 2" x 2" Boards - boards at 8' long. These are used to support the mattress.
  • 4' x 8' sheet of 1/4" Plywood - Important to use under the mattress if it is a new one. Otherwise, 4 or 5 extra 1" x 4" boards will work fine.
  • 5" or 6" 5/16 Lag Bolts and Washers - 20.
  • 1.5" Screws – Any kind of screws you may have laying around. You will need a couple dozen.
  • 2" Finishing Nails. You will need between 150 and 250 for holding the head and foot boards together.
  • Wood Glue - For gluing the wood.
  • 5/16 Metal Doweling Rod - Used as a little extra support between.
  • Sandpaper - This is dependent on the finish you might be looking for. You may require the (Dewalt palm sander): 1 package of 6, 60grit; 1 package of 6 120grit; 1 package of 6 220grit.
  • Stain - 1 946 ml tin. Whatever shade you prefer.
  • Varathane - 1 946 ml tin. Comes in several finishes.

Tools Needed

The tools mentioned below are a must have before you start working on the making of the bed. The more tools you have, the better it is once you start working. You can easily work with the wood if you have all the necessary tools.

  • Measuring tape – for all the measurements of the bed.
  • Saw – wood cutting or metal doweling.
  • Router – Optional. You can use this to make the board edges round though.
  • Palm sander – there is a lot of wood you need to the sander. You will need this.
  • Drill – a must have to drill holes.
  • Safety glasses – to avoid eyes full of wood splinters and dust.
  • Dusk mask – dust from most types of woods can be dangerous for either your sinuses or your lungs.
  • Nail gun – optional. You could also use a hammer.
  • Paint brush and sponge – Stain is easily applied with a sponge and Varathane requires a good paint brush for good application.

Pro Tips

  • You can get all the materials, tools and other equipment from any local hardware shop or you can purchase it online.
  • Make sure to use the good quality material to avoid any breakages.

Finally, the cut list:

  • narrow headboard slats (5) - 3/4 x 1-1/2 x 65

Step 1: Preparation for building a frame

step 1 preparation for building a frame
  • Drills and wood screws – Use the wood screws and drill bits that are designed for wood specifically. Using random drill bits might damage the boards or the drill machine itself.
  • Wooden Boards – Use the quality edge glue panels. These panels are cost-effective, beautifully finished and very resistant. You won’t need to use the sander to finish it.
step 1b preparation for building a frame
  • Tape measurement and Framing square – To get proper, clear and straight cuts, you will have to use a good measuring tape and a carpentry pencil. Double check all the measurements before making any cuts.

Pro Tips

  • Cut the wooden boards according to the size of the mattress.
  • Measure the mattress and add an extra ½” (1cm) space on each side of the bed frame.
  • Do not miss any step.
  • Use a framing square to mark measurements to perfectly align your wood board.

Step 2: Cutting the wood boards

step 2 cutting the wood boards
  • Set up for cutting the boards – use a woodcutter with a fine blade. You will also need a C-clamp and one more wood board with straight edges. First, place the second wood board and start cutting it exactly over the cut line at both ends. Then lock the wooden boards using a C-clamp.
step 2b cutting the wood boards
  • Marking the pilot holes – Use a measuring tape, carpentry pencil and framing square to mark the places where you will drill the pilot holes on the wood boards.
  • Appropriate distance – the distance from the edge of the board to its mark should be about half of the thickness of the wood board.
step 2c cutting the wood boards

Pro Tips

  • Lock the hole set up in place by using someone’s help or with the clamps and 2 saw horses.
  • Don’t risk injuring yourself as well as damaging the components.
  • This is the most important step to get the perfect corner joints.
  • Use the correct tools or else the board might split.
  • Keep steady or firm tables under the wood so that it doesn’t move while you cut it.

Step 3: Marking measurements

  • We have total three boxes for modular beds.
  • Two boxes are 56 inches and 20 inches deep.
step 3 marking measurements
  • Other one 40 inches long and 20 inches deep.
step 3b marking measurements
  • When you configure them together, you end up with platform that is 76 inches long and 40 inches across which is perfect for a twin bed.
step 3c marking measurements
  • Down the road, you can use them individually too.
step 3d marking measurements

Pro Tips

  • Cut a shape that you are comfortable with or just use the back legs as they are.
  • Use the jigsaw carefully and steadily to cut the correct marked positions.
  • Take the help of a professional if you are not up to the task.
  • Use a wood trimmer or router to even out the edges of the legs.
  • Make sure that both legs are exactly same in shape and size.​

Step 4: Constructing the bed frame

step 4 constructing the bed frame
  • Drilling through the board – drill the pilot holes using an appropriate drill bit with a compatible size of the screws. This would lock the two boards together with the wood screws.
  • Set up for bed frame joint – to set the corner of the joints, use 4 clamps and a square wooden post. This firmly secures the boards which have to be screwed together.
step 4b constructing the bed frame
  • Drill the bed frame to install the wood screws – Use the drill machine with torque control in order to make adjacent holes on the wooden board. This is to be done with a smaller drill bit.
  • Clamping the bed frame corner joint to drill – clamp the boards together again to drill holes for the joints.
step 4c constructing the bed frame
  • Tighten the bed frame joints with wood screws – Use screws to drive into the joint holes to fix the bed together. You can drive in the screws by using a simple manual screwdriver or an electronic screw driving gun.
step 4d constructing the bed frame

Pro Tips

  • Use a good drilling machine with torque control.
  • Start by using the drill at a low speed first so that it doesn’t slip from its position. You can adjust the speed once the drill is stable. This is to avoid the wood from splitting.
  • Make sure that the boards are perfectly aligned and the clamps are tightly locked.
  • Place the bed frames on 2x2 slats.
  • Gold the drill handle firmly to have a greater control over it.
  • Drilling must be progressive.
  • To tighten the bed frame joints with wood screws, make sure you have properly locked the corners.

Step 5: Installing the slats on the wooden bed frame

step 5 installing the slats on the wooden bed frame
  • Wooden bed frame side railings – Use a 2×2 lumber and fasten them with screws every 1′ / 30 cm to make sure the railings are at equal level.
  • Fixing the slats – the slats don’t have to be screwed into the frame of your bed but they just need to be fixed over the side railing at equal distance from both ends.

Pro Tips

  • Make sure that the frame is on the surface of the floor throughout the project.
  • If you notice that the corners are not right angled, make adjustments until they are equal.
  • The corner joints should be perfectly square.
  • There shouldn’t be any gap between the boards so as to avoid any damage in the long run.
  • The wooden boards should not have any damages or cracks. Use good material.

Step 6: Finish and final touch

You can use wood paint if you like to paint your bed. Or you can also use simple wood stain. It is totally up to you. Paint and polish act as anti-wood decays.

step 6 finish and final touch

Pro Tips

  • If you chose to paint, use a paint brush. Varathane also requires a good paintbrush for the application.
  • Wood stain is best applied using a sponge or gauze with cotton.
  • The corner joints should be perfectly square.
  • There shouldn’t be any gap between the boards so as to avoid any damage in the long run.
  • The wooden boards should not have any damages or cracks. Use good material.
