Excellent to raise height of furniture. My baby portacot was very low and i would strain my back to change nappies and lift baby out. These fantastic risers have helped raise the portacot by about 10cm for just the large ones.
We needed a large cutting table for craft work high enough to be able to use standing up. 2 cheap trestle tables from Bunnings and 2 sets of these - perfect!!!! Saved $100's
