The present invention is directed to a laptop platform for resting a laptop computer on a user's lap; the platform comprising a composite structure having risers to establish an air gap between the platform and the laptop. In one embodiment the platform is further configured with upper and lower layers including a plurality of ribs extending therebetween to define a pocket or pockets of air. The air pockets act as a second insulating source while the ribs aid in stiffening the platform. Further, a designated insulation material may be is adhered to the lower surface of the platform to create a third, separate barrier to heat transfer across the platform.
