Ordered that the order is affirmed, with costs.
The Supreme Court properly granted the defendant's motion for summary judgment dismissing the complaint. While on a service call to repair the defendant's burglar alarm, the plaintiff Frederick Boehme allegedly sustained personal injuries when he slipped after stepping on a stack of flattened cardboard cartons lying on the floor of the defendant's warehouse. Although the plaintiffs alleged that the dangerous condition which caused the injured plaintiff to trip and fall in the defendant's warehouse "consisted of a piece of cardboard on top of rollers on the floor", at his examination before trial the injured plaintiff testified that he "just assumed" that there was a roller under the cardboard. Therefore, the Supreme Court correctly rejected this allegation as mere speculation ( see, Dapp v. Larson, 240 A.D.2d 918; Leary v. North Shore Univ. Hosp., 218 A.D.2d 686).
Regarding the plaintiffs' assertion that the cardboard itself was a dangerous condition, the defendant had no duty to warn the injured plaintiff of a condition that he had not only seen before, but which was in plain view and could easily have been observed by him by the reasonable use of his senses ( see, Moran v. County of Dutchess, 237 A.D.2d 266; Perez v. New York City Indus. Dev. Agency, 223 A.D.2d 628; Zaffiris v. O'Loughlin, 184 A.D.2d 696). In fact, the injured plaintiff testified that he had actually seen the stack of cardboard cartons on which he stepped and that he purposely stepped on them.
