adjustable feet for bench/worktop support?

I am planning to a new bench/worktop about 3m wide x 750 deep x 820 high, straight across the back wall of the garage. The floor is solid concrete. Please any suggestions for strong adjustable & presentable feet to hold the bench supports? The aim is to have a perfectly flat & horizontal worktop which can be adjusted to true if deviations develop. The bench might be used for anything from delicate craftwork to heavy metal bashing.
TIA

You can spray paint them a nice colour if you wish, or for that industrial look thread them through corrugated drain pipe.

When I use them in wooden legs, I fit an appropriate threaded T nut (screwfix or similar)

My (main) bench is made from a bit of old 12x4.5" wooden beam with 4x2" to rear & 1.5" planks infill, all hinged(x3) to 4x2"timber fixed to wall. Front just 'rests'... on a couple more bits of 4x3" with large coach screws (for fine adjustment) with head into small socket in beam.
Has advantage that if, as I occasionally do, need more floor space, or to get two cars in, it just folds down against the wall. It even folds down with large Record woodworking vice still attached.
OK the timber was second hand and bought 35 years ago. Timber bought from rural 2nd hand yard in late 70s. Asked for prices and was told 1/2p per square inch per foot. {So much less than a pound per foot for main beam} Not bad I thought, and went hunting for required bits. Cost much less than I expected as he still worked in OLD MONEY! Just a bit of labour to remove nails from one edge.
I've a second smaller one with similar beam, covered with an Al sheet, that has a 5" Record engineers vice on swivel base. That uses 'recovered' keyclamps and heavy tube frame. Again, easy disassembled, but doesn't have the 'mass' which makes the main bench so nice for heavy work.
I think it important to have a bench that is not a liability to move Even if moving is a liability...
(must clear bench!) Jim
