Abstract: A catching device for use with a piece of upholstered furniture having a base portion, at least one wall portion extending upwardly from the base portion, and a crevice between the base portion and the at least one wall portion. The catching device includes an elongated receptacle sized and shaped for insertion into the crevice. The receptacle has a length selected to extend along at least a portion of the crevice, an upper sidewall shaped to extend along a wall side of the crevice, a lower sidewall shaped to extend along a base side of the crevice, and an end portion shaped for flexibly coupling the lower sidewall to the upper sidewall so as to form a closed end of the receptacle. The upper sidewall and lower sidewall are biased apart from each other such that when the receptacle is inserted into the crevice, the upper sidewall sealingly engages the wall portion and the lower sidewall sealingly engages the base portion.
