A base for a laptop computer. In one embodiment, the base has an upper surface with a keyboard and a lower surface opposite the upper surface. The lower surface may have two depressions extending from a forward edge to a rear edge of the lower surface. The depressions are configured to engage both the upper and side surfaces of the user's legs in a manner that restricts relative motion between the base and the user's legs. In one embodiment, the depressions may have a rough texture and/or a skid-resistant material to further restrict motion of the base relative to the user's legs. In another embodiment, first and second support members may be movably attached to the base to move from a stowed position to an unstowed position for providing more surface area to engage the user's legs.
