Abstract: An assembly of a platform assembly and a support structure, the platform assembly comprising a flexible platform, a plurality of support straps arranged to support the platform, a plurality of clamps supported by the support structure, the plurality of clamps provided along a side of the platform and clamping a side section of the platform, and a plurality of tensioning devices attached to the support straps at attachment locations and arranged to tension the support straps, wherein the attachment locations of the tensioning devices are positionable independently of the position of the clamps, and a method of assembly. A clamp having first and second clamping members having clamping surfaces, an actuation assembly comprising an actuation member coupled to at least one clamping member such that rotation of the actuation member, about a rotational axis, in a first rotational direction rotates the first and second clamping members relative to each other, wherein for a certain rotational position of the actuation member, the actuation member is moveable in a first axial direction relative to at least one clamping member and is coupled to the at least one clamping member such that said relative movement acts to urge the clamping surfaces closer together.
