The table top should be 2- 3 times wider than your piano as you will need to cut the table top in three strips. One for the base, one for the backing and one for the top cover.
My keyboard is 132cm x 30cm, so I bought the 150x75cm LINNMON table top.
Measure the width of your piano and cut the first strip for the base, it should be 4cm wider than your piano width in order to accommodate the backing strip.
My piano is 30cm and I cut the base at 34cm. Make sure that you cut the base strip with the finished straight edge showing at the front.
For the top cover, measure from the back of your piano to the start of the piano keys or keyboard controls. Remember to include the extra 4cm needed for the backing strip.
My piano controls started at 7cm so adding the 4cm, I measured and cut the top cover strip at 11cm. Make sure that you cut the cover with the finished straight edge showing at the front.
From the table top you should be left with a middle strip (with no finished edging). Measure the height of the piano and cut the backing strip 1cm taller. My piano is 15cm in height, so I cut the backing strip at 16cm.
The cut LINNMON pieces …
For the side strips, cut the LACK wall shelf exactly the same width of the base strip. So I cut the side strips at 34cm. Then placed the two side strips together on the backing strip, made a mark and cut the backing strip to size. Make sure that you cut the side strips with the finished straight edges showing at the front and top.
A piano keyboard height measured from the floor to the top of the white keys should be somewhere between 72 and 74cm. So I placed the piano on the base strip and measure from the bottom of the base to the top of the white keys, I have 17cm from base to the top of the white keys.
Next measure and cut the LALLE legs keeping in mind the height of your previous measurement to the top of the white keys. I cut the LALLE legs at 56cm, with the 17cm, it brought the measurement to the top of the white keys to 73cm.
Check if your keyboard has speakers on the bottom of the unit. If so you will need to cut out holes the same size as the speakers. Place your keyboard on the base strip and take the measurement of the speakers.
The LINNMON table top is mostly made of paper so I used a serrated knife to cut out the holes. Also make sure to measure and cut out a small hole on the backing strip allowing space for the plug lead.
Using a power drill screw the LALLE legs into the base strip and also screw in the backing strip and side strips. This is a difficult process as the LINNMON and LACK are essentially paper but they have some chipboard sections at the side, you need to try and drill your screws into these sections. One could also use wood glue if that suits.
Finally turn over your keyboard stand. Plug in your keyboard and fix the top cover with screws or a little wood glue.
And there you have it — a keyboard stand that looks like a piano.
