the computer table legs (from home office) have been married with castors meant for Ikea Besta units.
The table legs are high..90cm..a good height for my cutting table, and, as all furniture needs to be mobile to allow for flexible space configuration, I tried them out with the Besta castors, and it worked! I also added castors to the red table, which nestles nicely under the cutting table. The gate leg table will get wheels next, the bottom of the legs will have to be sawn level……this should be interesting and I have been putting it off.
