2 X 8 Bed





Introduction: 2 X 8 Bed

The intent of this bed project was to make a bed frame with basic tools as quickly and cheaply as possible.  Secondarily, I wanted to be able to break it down so it would be easy to move.  I have moved a lot over the last couple of years, and have always dealt with a mattress on the floor or on a boxspring on the floor.  It was time for a proper resting place that got me off the dirty floor without costing me a fortune.

This bed cost me about $22.  The only thing I bought new was the 2" x 8"s.  I got all the slats (the crosspieces that support the mattress), the bolts, the pegs that hold the headboard together, and the mattress for free.  Scrounge on!  

If you add fasteners to the mix, expect to spend another fifteen bucks or so.

You will need these tools:

Impact driver (or make do with your drill)
Ratchet and socket set
Circular saw
Drill bits
Speed square
Tape measure

You will need these materials:

5 2" x 8" x 8' yellow pine boards, straight as possible
5 2" x 6" x 8' yellow pine boards, salvage preferable
8 1/2" x 4" galvanized lag bolts
32 1/4" x 4" galvanized lag bolts
Wood glue
1 1/2" x 3' dowel


Step 1: Framin'

The first step is the easiest:  cut two of the 2" x 8"s to 75" and two of them to 57".  These directions are for a regular double bed.  I made the frame to be bigger than the mattress by one inch all the way around.  For a full rundown of common mattress sizes, see the Wikipedia page here: http://en.wikipedia.org/wiki/Mattress.

So, the long sides are one inch longer than the mattress, and the short sides are four inches longer than the mattress, to accommodate both one inch of play on the mattress and one and a half inches on either side to overlap and create the joint with the long sides.

To reinforce the corners and create a spot for the legs to attach, I put a brace in each corner that was made from one of the leftover scraps of 2" x 8".  Just cut the biggest right triangle you can out of the material.  Make four of those.

Lay out the box on a level surface.

Step 2: Runners and Slats

Using the T-bar guide on the circular saw, cut some 1-1/2" wide strips out of a piece leftover from making the frame.  The T-bar fits through a slot near the front of the side and allows you to set it to a certain width.  Run the saw while keeping the flat face of the T-bar against the factory edge of the wood and you end up with a nice straight rip cut.

Screw and glue these to the bottom inside of the long sides of the frame to create the runners that the slats will rest on.  Use drywall screws that won't poke through to the outside -- 2-1/2" long ones are perfect.  Make sure these are secure -- they take most of the weight of the mattress and its occupants.

Cut your slats to fit nice and tight inside.  I used salvaged rafter tails from an old shed.  Doesn't matter if that wood looks crummy or is a little warped or whatever, as long as it is strong.  You could use thinner pieces, like 2" x 4"s, but I'd be cautious.  They will probably sag over time, spanning four feet unsupported.  Put a lot more in, and make sure they bow upwards.

Step 3: Legs!

The legs on this bed are really simple.  They may not be the most elegant, but they look nice enough and get the job done.  

Cut eight right triangles out of your scrap wood -- mine were the width of a 2" x 8" on their two equal sides.  On four of them, measure 3/4" in from one side and space two holes how you want.  Flush two triangles up to one another.  Drill 1/8" pilot holes, then a 1/2" countersink for the lag bolt.  Glue and screw the feet together.

Once the foot is made, hang it off a right-angled surface, like a milk crate, and cut off the point so it sits nice and flat on the ground.

Screw and glue the feet to the corner braces with 3" drywall screws.

Step 4: All Together Now

Lay the pieces out in a rectangle with their feet.  Mark each end of each board and each foot with a letter or number so you know which three belong together in each corner.  Mark out and drill three 1/8" pilot holes and 1/2" countersinks in each end of each frame board, 3/4" up from the bottom edge, to go into the corner braces.

Attach two corner braces/feet to each long side with three 1/4" lag bolts.  I popped  a little drywall screw in each brace just to hold it while I got the other three into place.  Stand up the short ends of the bed and get them attached to one side.  Roll the frame down so the feet are sticking up in the air and attach the last side.

Pilot hole and countersink two 1/2" lag bolts through the ends of the two short sides and into the end grain of the long sides.  Remember, the countersink hole needs to be bigger than the diameter of the socket that turns the bolt head, not the bolt head.  Ratchet in the lags.  As you can see in the one picture, you can screw a temporary block into the backside of the frame to have something to clamp against to pull this sides into line.

Step 5: Headboard

The head board is the last step.  Mark out and drill five or six holes in the head end of the bed frame (typically the end that looks the worst, as it will usually be against the wall) and drill about three or four inches down into edge with a 1/2" bit.  Hammer and glue in some pegs made from the dowel, 6-8" long.  

Hold your headboard up to the pegs and scribe lines across so they align, drill, and hammer and glue it down.  Obviously, I miscalculated the thickness of the mattress a little bit and the headboard doesn't stick up much.  Doesn't matter if you have your bed against a wall.  If you want a bigger headboard, just lengthen your pegs and slap a 2" x 10" or 12" on there, or two 2" x 8"s.

Pop the mattress in and enjoy!

Very nice build. I built pretty much the same frame years back without the legs. Very well done and see a lot of nice improvements over the design I had. Well done.

My son and I just completed his California King based on this Instructable -- thanks! We made some modifications, of course. And it took longer and cost a bit more ($150 all-in) than I estimated, but it turned out fantastic. I've attached some images showing various stages

The main differences are:
a) the size
b) use of 8 2x6 slats (and we might add 2-4 more)
c) 4x6x20 posts for legs (it's *really* high off the ground, we may cut them down a few inches)
d) 2 L brackets on each leg to augment the 4 lag screws
e) a single coat of stain to make the pine look slightly different
f) no headboard

Having a 3/4" socket wrench for the large lag bolts, and a 1/2" socket bit for the small lag bolts, was really helpful. I used a 5/8" spade bit to make the recesses for the small lag bots, and a 1" spade bit for the recesses for the large lag bolts.

We had to carry the frame upstairs and do the leg and slat installation in the bedroom. It would be *really* unwieldy to have had the legs mounted while maneuvering it through the house, esp. up the stairs.

BTW, I don't think a center leg is required given all the slats.

Hope people find this useful, and thanks again to wholman for starting it off!

The lag bolts are 1/4in x 4in. that would convert to 6.35 mm x 101.60mm

Hi, I'm from Spain, and I have got a problem with the lag bolts, in concrete is the measure, I guess that the measure in your materials are in inches, my question is this: Can you or someone else tell me what measurements have in milimetres the lag bolts?
I've looked in internet with a conversor of longitude, as I gave the converter was 25mm, so here it is 2.5cm

How tall is it from the bottom of the frame to the floor? Do the legs pick it up that far off the ground?

I was thinking about using 4x4"s instead for legs or maybe 2x10"s to provide a few more inches under the bed.

you could easily make the legs longer if wanted or ad the 4 X 4's i see different ways to go with this bed.

Mine ROCKS! Only thing I did differently is not use the 1/2" x 4" bolts, those things are huge! So I just used the 1/4"s. I love the natural bolt and wood look was really cool, but it wasn't in my design scheme. So, I ended up really globbing on a black walnut color stain, over the bolts and all.

I am not done with my own headboard, but when I do - I'll get a picture up.

Thank you soooo much for this, super fun and my introduction to using lag bolts has opened up a whole new world!

I liked this so much I made a slightly modified version. I used 2x12s instead of 2x8s and left off the headboard. I also made the legs a little longer to accomodate more dust bunnies. Thanks for the inspiration. http://bit.ly/erQo9l

hey man, looks awesome! thanks for letting me know . . . so rare to find someone who actually did one of my instructables . . . hope its nice and comfortable.

Very nicely done. I really like the design's ability to be adapted. Really inspiring for me. I was going to design my own but this one is already laid out so well. Good clear photos too!
