Fitted sheets that won't stay put are one of those small annoyances that quietly ruin a good night's sleep. Harbor Sheet Clips solve the problem for good. Each clip fastens securely to your mattress edge with a precision-ridged grip pattern that locks fabric in place — no more bunching, no more late-night re-tucking. The included transparent adhesive strips keep each clip anchored invisibly, so your bed looks just as clean as it feels. Made from durable, tear-resistant PVC that holds its shape over time, these clips work with fitted sheets, flat sheets, and mattress protectors on any bed size. Especially great for households with kids or pets who treat your bed like a trampoline.
