Abstract: A bed sheet attachment system with a pair of expansion panel assemblies that attaches a top cover to a bottom sheet by a plurality of panel strips connected by a plurality of fastener strips. The fastener strips are prevented from opening during sleep by a plurality of snap tabs. The plurality of panel strips provides increased cubic capacity between the top cover and bottom sheet for the sleeper to slip into and move within the bed. The plurality of snap tabs allows the panel strips to be separated at discrete lengths to accommodate the sleeper's needs and desires for the arrangement of the top cover during sleep. The bed sheet attachment system simplifies the daily making of the bed by maintaining the proper position of the top cover during sleep so that the user merely smoothes out the wrinkles on the top cover upon arising.
