We created the answer to keeping bedsheets taut and in place with our new patented Sheet Stay-Downs™ as USA made sheet strap. Our fitted sheet corner or criss cross straps feature the patented "no-slip"® composite plastic gripper clasps™, the harder you pull the tighter they grip, as well as our unique patented Velcro®-type tension adjusting system. They are the only sheet straps which feature the ability to adjust the tension after attaching the clips. One person can easily attach the sheet straps without lifting the mattress. No matter how you toss or turn, Sheet Stay-Downs™ will keep your fitted sheets in place on any size mattress. They are offered in either a short corner "quad" style or in a long criss-cross "dual" style. Made in U.S.A.
