What mattresses does it fit?
Zlumber Lock is a total social butterfly—it works with everything! Whether you have a Twin, California King, memory foam, or a chunky 22-inch pillow-top, our system adjusts to fit your bed perfectly.
Is it hard to install?
Not at all! It’s a one-and-done setup. You place the permanent bases under your mattress corners once, and then you just slide the locking strips on and off whenever it’s laundry day. Easy peasy!
What is included in the Zlumber®Lock™ package?
Each standard package includes:
- 4 corner holders (1 for each mattress corner)
- 4 locking strips
- Installation instructions
Some bundles may include extras like a spare strip or other accessories—check your retailer’s listing.
Does it work for adjustable beds?
Absolutely! In fact, that’s where we shine. Even when you raise the head or foot of your bed, the locking strips keep your sheets from popping off the corners.
