"I used to wake up every single morning with one corner of my fitted sheet completely off. I thought it was just normal until I tried these. Installed them once and haven’t had to fix my bed in over two weeks. It feels like a hotel bed now."

Why not just buy deep-pocket sheets?
Why not just buy deep-pocket sheets?
Deep-pocket sheets help, but they don't solve the physics problem. Toppers, protectors, and adjustable beds still create tension and slippage. CornerLock works WITH your existing sheets to keep them locked in place.
Will it break like cheap clips?
Will it break like cheap clips?
Not if we can help it. CornerLock is built with reinforced plastic and a ratchet lock mechanism designed for repeated use. If it ever breaks, snaps, or fails—we replace it free under our Lifetime Replacement Guarantee.
Will it rip or damage my sheets?
Will it rip or damage my sheets?
No. CornerLock uses a fabric-safe grip surface—no metal teeth, no sharp edges. Safe for sateen, bamboo, jersey, microfiber, and all standard sheet materials.
Does it work on adjustable beds?
Does it work on adjustable beds?
Yes. CornerLock is designed to hold through bed articulation. Whether your bed is flat, inclined, or cycling through positions, corners stay locked.
Will it fit my deep mattress or pillow-top?
Will it fit my deep mattress or pillow-top?
Yes. CornerLock works on mattresses up to 18" deep, including pillow-tops, memory foam toppers, and mattress protectors. If your fitted sheet reaches the corner, CornerLock will hold it.
Is it hard to install?
Is it hard to install?
No. 60 seconds per corner. No mattress lifting required. Attach the clip to your fitted sheet corner and lock it in place. Done.
Do I have to reinstall it every time I change sheets?
Do I have to reinstall it every time I change sheets?
No. Remove CornerLock when washing sheets, then reattach in seconds. No setup required after the first install.
