Review on 4 Pack Adjustable Triangle Bed Sheet Holder Straps - Elastic Mattress Sheet Clips for Securely Keeping Sheets in Place - Heavy Duty Grippers Clips for Bedding - KALLC Bed Sheet Fasteners by Jeremy Watkins

Love these, I have cotton sheets, nothing fancy and they work great although I'm sure over time if they get really tight they will rip the sheets , but that's the case with all sheet clips or they'll snap, but I can't tell how they work with really good cotton bedding, bamboo or silk bedding. I'm not sure if trendy sheets are stronger and stand up to stretching, but it's definitely worth it because before that, my sheets were unbuttoned and I have an adjustable bed frame to keep them from wrinkling and being uncomfortable to sleep on no matter what I do , the bed is set to max height or flat, they don't seem to wrinkle and they stay on the mattress. It can be a chore to take them off when washing the sheets. You have to flip the mattress but so far a great product all round
