A floor panel, comprising: an upper surface; a floor contact surface; at least a recess end face including: - an upper lip adjacent to the upper surface provided with a recess first upper lip surface adjacent to the upper surface; - a lower lip; and - a recess including at least one upper recess first contact surface, and a recess guide surface; at least one protrusion end face opposite to the recess end face, the protrusion end face comprising: - a protrusion first upper side surface adjacent to the upper surface; and - a protrusion comprising at least one upper protrusion first contact surface, and a protrusion guide surface, wherein the protrusion end face and the recess end face of an identical one of the panel are configured and dimensioned to be coupled by positioning the protrusion on the lower lip of the recess and applying a compression force in the direction substantially perpendicular to the plane of the upper surface which causes the protrusion guide surface to contact the recess guide surface and translates the protrusion into the recess; and wherein, when the protrusion end face and the recess end face of an identical one of the panel are coupled, the upper protrusion first contact surface engages the upper recess first contact surface to prevent decoupling of the panel in a direction perpendicular to the plane of the upper surface, wherein for said floor panel, a recess second upper lip surface is provided at an outer end of the upper recess first contact surface and joined to an upper recess second contact surface, wherein the recess first upper lip surface is parallel to the recess second upper lip surface; the upper recess first contact surface is parallel to the upper recess second contact surface, and for said floor panel, a protrusion second upper side surface is provided at an outer end of the upper protrusion first contact surface and joined to an upper protrusion second contact surface, wherein the protrusion first upper side surface is parallel to the protrusion second upper side surface, and the upper protrusion first contact surface is parallel to the upper protrusion second contact surface, characterized in that said floor panel has a back notch in the lower surface of the protrusion and the upper protrusion first contact surface is arranged at a vertical position higher than the back notch and in that the recess includes at least one lower recess contact surface, the protrusion comprises at least one lower protrusion contact surface, and the lower protrusion contact surface and the lower recess contact surface are inclined at a 90 degree angle relative to the upper surface, wherein, when the protrusion end face and the recess end face of an identical one of the panel are coupled, the lower protrusion contact surface engages the lower recess contact surface to prevent decoupling of the panel in a direction perpendicular to the protrusion first upper side surface. an upper surface; a floor contact surface; at least a recess end face including: - an upper lip adjacent to the upper surface provided with a recess first upper lip surface adjacent to the upper surface; - a lower lip; and - a recess including at least one upper recess first contact surface, and a recess guide surface; - an upper lip adjacent to the upper surface provided with a recess first upper lip surface adjacent to the upper surface; - a lower lip; and - a recess including at least one upper recess first contact surface, and a recess guide surface; at least one protrusion end face opposite to the recess end face, the protrusion end face comprising: - a protrusion first upper side surface adjacent to the upper surface; and - a protrusion comprising at least one upper protrusion first contact surface, and a protrusion guide surface, - a protrusion first upper side surface adjacent to the upper surface; and - a protrusion comprising at least one upper protrusion first contact surface, and a protrusion guide surface,
