There was a need.
I created a solution.
Custom foot risers to lift the furniture.
I did two sets - one for the coffee table, and one for the sofa. This isn't fine furniture we are talking about, but it comfortable and I think the cleanliness will out weigh the incongruence in design.
Wood - as thick as needed for proper clearance.
Stain - to match existing finish
Screws - to affix riser to furniture
Felt pads - so you don't mar the floor
Drill press and drills
Step 1: Measure Clearance for Cleaning Droid
Select your wood accordingly. I used a nice piece of Oak 1" thick for the table risers and a Pine 2"x4" for the sofa.
Step 2: Measure and Cut Wood Blocks
Sweep out the dust bunnies and cat toys that were hiding under there.
I was able to unscrew the sofa foot to bring it to the shop, but had to do the table leg measurement on location.
I traced the bottom of the existing leg onto the wood to get the widest point measurements. This will be the mating surface at the top of the new riser.
Cut the four blocks to size on the chop saw.
My furniture has an angle cut into two sides of the legs, so I used a straight edge to follow that edge, marked it and cut on the band saw. I matched the angle of the second side and cut it as well.
Repeat process until you have enough.
Step 3: Drill Holes for Mounting Risers
I drilled a larger hole than the size of the screw head, then drilled a smaller hole about the size of the screw shaft.
Step 4: Finish Sand Your Risers
A smooth finish will make the stain look better.
Step 5: Stain the Risers
Mine was a mahogany color and it had a polyurethane coating built in.
Glop it on, smooth it out, and watch it dry. Seriously - sit down and watch it dry. Contemplate how this simple project will cut down on dust in your home. How the cats will have an easier time collecting lost toys and how far you will have to reach if the droid gets stuck under the sofa. If you are done with your zen moment, go do something else - this stuff takes a while to dry.
Step 6: Drill Them and Screw Them On
Line up the risers and using a drill bit a bit thinner than your screw, drill a pilot hole into the existing table leg or sofa foot.
You can add wood glue at this point if you like. I didn't, but you could for a more permanent bond.
Screw them in snugly.
Step 7: Cut Felt Pads, Stick Them on and Be Protected
Do that. Cut four pads to fit on the bottom of the stack. Peel off the backing and stick them on.
Step 8: Flip Your Furniture Back Over and Test Out Your Cleaning Droid
Enjoy your new view... it's a little higher than before!
Test out your Neato or Roomba and see if they can get in there and rustle up some dust bunnies!
I used the tools at the Tech Shop in San Carlos California to create this project.
It was nice to have a full wood shop at my disposal, so I used it. You can do this with hand tools if you like, but it's faster this way.
