What Is Zlumber® Lock™?

Zlumber® Lock™ is a corner-based sheet holder system that sits under your fitted sheet and locks it to your mattress, so it stays smooth and snug — even for restless sleepers, deep mattresses, or adjustable beds.

Low-profile, discreet design

The system hides under your sheet, so your bedroom still looks clean and minimal.

Hotel-tight sheets at home

Wake up on a smooth, flat bed instead of a twisted fitted sheet.

Secure & tug-proof

The locking strips grip the sheet at each corner so it doesn’t slip or pop off.

Fast, simple setup

Corner-specific design makes the initial install quick; after that, you just slide the strips in and out when changing sheets.

Universal fit

Designed to work across common bed sizes and mattress types, including many deep or pillow-top mattresses.

Built to last

Made from durable materials and backed by a warranty and easy returns for extra peace of mind.

How Zlumber® Lock™ Works

1 Install the corner holders

Place a Zlumber® Lock™ unit on each mattress corner. This is usually a one-time setup.

2 Put on your fitted sheet

Stretch your fitted sheet over the mattress like normal, making sure it wraps over each corner.

3 Slide in the locking strips

With your fingers, find the groove on each corner holder and slide the strip into place. It clamps the sheet tight — and stays hidden under the fabric while you sleep.

When it’s time to change sheets, you just slide the strips out, swap the sheet, and slide them back in. The corner holders stay on the mattress, ready to go.
