Here's my materials I used
Car seats - $75
angle aluminum - Free
Wood - Free
Drawer slides - $10
Welding - Free (knew someone)
Misc. hardware - Free-$5
That cost me around $80
Now if you choose to build something as cool as this you can use any materials you feel comfortable using, I chose aluminum because we had extra laying around, it is sturdy when all welded together and it was free.
Step 1: Make a Plan
after finding the seats that satisfy you, start measuring so you know what you need to build below it.
I got my seats out of a totaled 2007 Grand Prix. You can get what ever you like. older seats are generally cheap and new ones of course are more pricey, but it all depends who you get them from. Fortunately the place I got them from charged me $25 a seat = $75
Step 2: Finding Pieces for Frame
after you measured the dimensions for the seats start cutting and welding
here's how mine turned out. a simple rectangular frame.
Step 3: Mounting the Backrest
I cut off each side to give it a 25 degree angle so it would put the back rest at a 65/125 degree angle.
after pieces are welded onto both sides. I clamped a long angle aluminum piece so I could drill holes correctly. after that I bolted them on because I want the back rest to be removable for storage. these will be for the back rest
Step 4: Mounting Bottom Seat
DONT let your dog get a hold of the rope!
Step 5: Mounting the Backrest
I am not really sure how to describe this step I was hoping my pictures would it explain it better but I will do my best. I set the back rest on the vertical angled aluminum pieces. I set a car jack underneath to support it and so I know how high I need to bolt it, also so it rests properly on the bottom seat.
I know I did not explain it well but I hope the last picture explains. there are 4 holes when you fold the seat down. I cut the vertical pieces down to the right height the welded a horizontal piece across and bolted the back seat to the horizontal piece.
Step 6: Building Room for Storage
Step 7: Attaching Drawers
Basically all I did was weld some pieces on the bottom to support the rails for the drawers. I attached the rails to the drawer first, then clamped that to an angle aluminum piece and welded everything down so I would have the exact spacing and wouldn't have to measure anything. the drawer fit perfectly but slides a little rough because its so wide, I would probably suggest putting a slide in the middle. but have not done so
Step 8: All Done! But Not Really..
Step 9: The Other Seats
I like having it on the ground, they are nice and comfortable gaming seats. But what if I want a nice desk chair. I wanted best of both worlds. I have not seen anyone really do anything like this, but I think If I took a car jack and mounted that on the bottom with some wheels it could be both a low floor gaming chair or a high desk chair. look at the drawings to get a picture of what I am talking about
