4-in-1 Modular Multi-Part Chair/Table/Bookshelf/Bench With Stool

I made 4-in-1 Modular Multi-Part Chair/Table/Bookshelf/Bench with Stool, designed using Fusion 360 and built using human ingenuity. Here's everything it can be used for:

Chair: It can function as 2 comfortable chairs with a table/foot rest/stool.

Table: It can convert into a table, with a flat surface for dining, working, or displaying items, while also having one chair left over to sit in.

Bookshelf: The chairs when put together act as a bookshelf or storage space for books, magazines, or other items.

Bench: It could be extended into a bench, offering additional seating or serving as a display surface.

Stool: Finally, there is a stool/footrest component that’s separate, providing a place to sit, rest, or use as additional support.

This is all for maximum space efficiency, simplicity, and practicality. Though, the design can definitely be improved since im just a student.

1. Getting Ready/Preparing
2. Getting Supplies
3. Beginning the build.

All materials can be found at Lowe's or Home Depot (I went to both)

3/4 in x 16 in x 6 ft stain grade wood project panel

3/4 in x 16 in x 3 ft stain grade wood project panel

12 of 1 in x 2 in x 6 ft whitewood boards (the actual dimensions will be a bit less but this is what it will say)

1/4 in x 2 ft x 4 ft plywood board

4-6 clamps

Everbilt #8 x 2 in screws

Everbilt #8 x 1-1/4 in screws

Titebond Ultimate Wood Glue

Drill

Driver

Pilot hole drill bit

Phillips screwdriver drill bit

Saw

Wood Glue

The first step is getting ready. Drive on down over to your department store of choice and make sure you have everything you need from the supplies!

By the way, remember that we are mainly using the 1.25 in screws and not the 2 in screws, we only use the 2 in screws around once.

Using your saw, cut the 6 foot by 16 in project panel into 2 pieces that are 15.25 in long each.

Using your saw, cut the 6 foot by 2 IN planks into 4 pieces that are 15.5 IN long each, this will use up about 1 planks.

Drill pilot Holes in the corners of each of the 16 x 15.25 IN pieces in the Orientation shown

The holes should be slightly inward on the 16 inch side, so that they are in the center of the shaft when it is added as shown in the photo with the measuring tape.

Apply the Titebond Ultimate Wood Glue to the area around two of the pilot holes which are next to each other. Make sure it is in the shape of the plank.

Quickly now, attach two shafts where you applied glue and screw through the pilot holes. Make sure it is aligned properly!

On the other panel (we can call it panel b), repeat the same thing, connecting the shafts already connected to panel A also to panel B so panels A and B are connecting by two shafts. Then add the remaining two shafts, repeating the same steps again until both panels A and B are connected by 4 shafts.

Saw some more of the large 6 foot by 16 IN planks into 3 pieces of length 17 inches and 4 pieces of length 34 inches

Use the glue/Screw method to attach the 34 inch shafts to the back of the box in the orientation shown. One should be at each of the edges, and two should be inward from each side, 4.6 inches inward from the outside edge as shown in the image. It is imperative that at this stage you attach the shafts in the correct place.

The glue screw method is to:

1. make pilot holes in the places you want your screws to go
2. applying some glue to the object and surface
3. putting it in place, aligning it where you want it to be
4. and then screwing through the pilot holes to secure it

Once again use the glue/Screw Method to Attach the 17 inch shafts to the front of the box we just made in the orientation shown.

The outward edge of the shaft should be 3 inches from the edge inwards, and the third shaft should go in the middle, as shown in the images above

This is what your chair should look like right now.

Saw out another shaft piece 15.25 inches in length. We will be using this to bridge the gap between all the top pieces. This is also where we will use the 2 inch screws, and the only place we will use the two inch screws.

Your shafts might be uneven like ours were, so you can saw in a straight line to make sure they are all aligned so its easier and possible to add the top connector.

In The Top Connector, drill pilot holes in the spots where 2 in screws would penetrate through to the shafts, as shown in the image.

To help strengthen the connection, add glue to the top of each shaft.

Align the top connector in place and screw in all 4 screw holes with the 2 inch screws

Repeat steps 2 through 16 to build another chair.

Repeat steps 2 through 7 to build another box. With this one, we will not be making a chair but will be making a "side table" piece or an extra modular bit that brings this all together.

To make a side table, first, saw out three 15.25 inch shafts.

Then glue/screw them in in the places shown in the orientation shown in the images.

The outer ones should be 3 inches from the edge, and the middle one should be 4 inches from the outer one as shown in the image(s).

To attach the backs of the chairs, we're going to saw that 2 ft x 4 ft plywood piece into 2 pieces 15.375 in long and 1 piece which will be however long remains.

Reposition your chairs to look like this. It makes it easier to apply the backs.

You can use your finger or a brush for this step. I used a brush.

Align one of the 15 3/8 in x 2 ft plywood boards on the spot you placed the glue and place weights on top of it, as well as clamps to make sure it stays in place. Wipe any excess glue.

Apply Glue to remaining 1/4 of Chair 1

Place the second piece which is 15 3/8 in on top of chair 1 aligned on all sides. It will stick out halfway, but that's okay as we will cut this excess with our saw and use it for the other chair.

Place weights and clamps on top of the second piece to secure it.

Saw off the excess wood which dangles off the edge from the second piece of wood. We will use a circular saw for this.

Apply glue to the first 1/3 of Chair 2. We will apply the excess piece/half piece we just cut off here.

Place the half piece and add weights and clamps, wiping off any excess glue.

Use your brush or finger to apply glue to the remaining of chair 2.

Use the piece leftover from the plywood cutting, laying it flat next to the half piece. There will be a little sticking off the edge, but that is okay as we will cut that off using a circular saw.

Add weights and clamps to the last piece on chair 2 to secure it.

Saw of any wood hanging over the edge of chair 2 using your circular saw. Once this is done, you should be done.

With that, you should be done with your 4 in 1 modular chairs/table/bigger table/bookshelf/bench system!

To make your chair look better and be better functioning, here are some things you can do.

1. Attach some furniture pads to the bottom of everything so it doesn't scratch your floors.
2. Stain or paint it all for a cleaner finish.
3. Use screw covers for a more aesthetic look.

If you have any more ideas, comment them alongside your build!
