A freestanding trough has an elongate trough body 12 and transverse restraints 14. The trough body has a bottom portion 16 integrally formed with two side wall portions 18 from a resilient semi-rigid sheet. The restraints 14 extends transversely across the inside of the trough, intermediate the ends of the trough body 23, lower than upper edges of the side wall portions but higher than the bottom portion. The side wall portions 18 are restrained from moving outward, away from a longitudinal centreline of the trough, at least in part by a tension in the restraint 14 and the side wall portions are maintained upright in part by the tension in the restraint, and in part by the resilient semi-rigidity of the sheet.
