Assembly comprising two height-adjustable supports such as for a table top, the supports at their upper ends being mutually connected by a beam. The height-adjustment takes place in that a threaded rod is rotatably received in the upper part and extends into a nut, fitted in the lower part of the support. At its upper end, the threaded rod is connected to a bevel gear wheel, which is in engagement with a bevel gear wheel connected to a coupling rod, coupling the threaded rods of both supports to each other. The lower part is led across the upper part, and a screening plate extending around the circumference of the support is connected to the upper part, the screening plate running downwards and abutting the inner circumference of a tubular part connected to the lower part of the support.
