【Patent Pending Clampless Locking System - Unbeatable Grip】Forget about flimsy clamps or straps that get caught in the sheet. Our exclusive sheet holders use industrial strength elastic bands and a 360° wraparound grip to securely lock the sheet in place without damaging the fabric. Perfect for restless sleepers, adjustable beds or heavy mattresses. No slipping guaranteed. 【Anti-Turning Magic】Installs in 10 seconds. No struggling, no turning. Slide the base under the mattress corners and you're ready to go. Perfect for: heavy beds (no lifting!), elderly/lonely installation (no strength needed) and late night fixes (works on made beds!). No more old-fashioned clamps that require mattress acrobatics. Our Pegs, Locks and Forgets 【Universal Fit for All Adjustable Height Mattresses】Forget about fixed height grips that fail. Our improved sheet ties work perfectly with all beds (2.7 inches and up): low cribs, hospital/camper mattresses, standard beds or plush mattress toppers. One tool rules it all - forget about mismatched grippers for different beds. No Gaps in Corners: No gaps = no slippage. Our flexible edge design automatically conforms to round, square or serrated mattress corners for a 360° seal. Our sheet holders grip like a vise. No Sheet Damage: Gentle on sheets, won't slip. Our soft, pinch-free bands grip securely without snagging, tearing or leaving marks - even on silk, bamboo or delicate materials. Cheap clamps damage sheets over time. Ours protect your investment.
