B&M were selling folding tables for £9.99... is as good as any or are you a WUM?
Our kid has a tiny fold up alloy table that is only a couple inches off the floor. Sounds like its not up to much but i used it camping a few times and it was great.
Will try and find the name.
Sounds like the Hi Gear Compact? ..
