The Original USA Patented ZlumberLock - Secure Sheet Holder with Heavy-Duty Mattress Straps – No More Loose Bedding, Universal Fit, Easy One-Time Installation

Love these!. Much easier than the elastic straps. We were concerned the fabric corners would get worn out, but it is worth it to be able to make the bed quickly......and sheets stay put during sleep. My husband somehow pulls bottom sheets to his side. No moving with these corners. Sheets are taught with the straps, but with these corner holders, the natural stretching of the fabric will occur. Also, this product was more expensive, but seemed a better quality and less likely to break.

We have an adjustable Tempur-Pedic mattress that vibrates and every morning the fitted sheet became untucked. We got so tired of the battle so I ordered these in March 2026. I installed them on our mattress and the next morning the fitted sheet was STILL TUCKED! One week turned into two weeks and three weeks turned into a month with the sheet still tucked in. Installing them is really simple, it just slides under the mattress & changing the sheets is very simple as well. It also holds the flat sheet in place as well, so matter how much myself or my husband moves at night, we know the sheet is staying put. It also comes with a sleep mask and a tool to help you in making the bed. If you're struggling with the sheets coming untucked then I would definitely order this!

These things really work! We were tired of our sheets and mattress cover constantly sliding off the corners of our mattress. We took a chance with this product and it works fantastically. The sheets and mattress cover didn’t move a bit all week. The sheets stayed so much smoother throughout the night. The sheet holders were super easy to install and the little sliders came out easily when I changing the sheets. We’d recommend this product to anyone needing their sheets kept more securely on their bed.

The ZlumberLock is excellent. I am a side sleeper who rolls over frequently to change sides while sleeping at night. My mattress cover and fitted sheets came off the edges of the mattress while switching sides and caused me to lose sleep. I purchased the ZlumberLock to resolve this problem and it works perfectly! I have been using it for about a week now and have not experienced any problems. The fitted sheet and mattress cover stayed in place perfectly even when I flip flop from side to side. There are cheaper substitutions of this item on the market but I prefer the ZlumberLock because it appears to be more durable than cheaper versions. I highly recommend the ZlumberLock and rate it a 5 out of 5.

These side supports work! So much easier than you might expect. Once you get the hang of it you will be so glad not to have to use suspenders. Sheets stay put, simple but effective. Note: this product tho effective for most sheets doesn't hold on Bamboo ones, they still slip not a lot but enough to be annoying for who want a tight sheet with no wrinkles. Granted Bamboo sheets Are thin but know on these sheets you will still need suspenders .

This product works! After a year of the bottom sheet becoming undone, the bottom sheet now stays exactly where it belongs. The reason for 4 stars is that I had a very challenging experience to make it work which took over an hour going back and forth from the instructions and "help" video for assistance. I learned the hard way that the doing the corners as illustrated will make it or break it. I'm glad that I figured it out, because the time I put in has made a world of difference for me. In time I will become a pro at this.

I tend to buy gadgets. Some work better than others. This one is a total success. Old mattresses were 7" tall (yes I'm dating myself) and more bendable. My current mattress is 11" and heavy and not bendy. Other mattresses are even taller! I love my sheets that I bought when I had a 7" mattress and they're still usable but don't really want to stay tucked under the mattress (I'm talking about fitted sheets here). I've got elastic straps that clip onto the sheets--you know the ones?--and go under the corner of the mattress. Remember that heavy, not bendy mattress? I struggle 1) to get the clips positioned in the best position and 2) I'm trying to hold up this heavy mattress with one hand and then with only one hand left, position the elastic straps under the corner of the mattress! So frustrating. I even bought this big wedge thing that you stick between the mattress and the foundation to hold the mattress up but still very difficult to do. This ZlumberLock thing? Genius! I've used it once and am sold. I had to lift the head of the mattress up fairly high (up against the wall) to slip the gadget onto those two corners but that's a one time thing as they stay there permanently. Start by putting the sheet onto the head of the bed first--I'll explain why in a minute. The head of the bed is probably the harder area to do this because I wanted to hold the fitted sheet down while I slid the strap into the slots on either side of the corner apparatus. Have to double-check that you got the strap actually into the slot, especially on the wall side so took me a couple tries but I can see how it'll get easier as I do it more. Now, onto the bottom of the bed. Remember my started life on a 7" mattress? This means that my current mattress is 4" shorter than my old mattress. This means that if I want the top sheet to be high enough on the bed to be able to fold it back there isn't that much under the mattress holding it in place and I've pulled it out before. I've been considering sewing a 6" strip of fabric onto the end of the sheet to get it tucked farther under the mattress to hold it better. NOW I put the fitted sheet onto corner apparatus--don't put the plastic strip into the slots yet--and then put my top sheet over it and guess what? I can put the top end where I really want it at the head of the bed. DO NOT tuck this sheet under the mattress yet. Tip: the excess sheet at the corner of the bed? The part you usually neatly fold and tuck (hospital corners)? Let it hand loose AT THE CORNER of the mattress. Don't try to fold/smooth it anywhere. Reason I know to do it this way? Because folding it towards the side didn't work. NOW put the strip into the slots. Because you know have 2 layers of fabric you have to also get into the slot it's a wee bit harder to do. If you had all that excess top sheet fabric also it just don't work well. And the excess fabric fits right under the corner area of the plastic strip that goes into the slot and holds the sheets in place. No slot around the corner of the mattress. THEN I tucked the excess under the mattress. No hospital corners but I don't care! The quilt covers it up so no one sees. This product was a bit pricey but I liked that it was so sturdy looking (which it turned out to be). I always check the reviews and they were solid. When I opened the box the corner pieces looked huge but fit perfectly. The plastic strips you slide into the corner piece slots? Very sturdy. Stiff but bendable. And they give you 5, not 4. Tuck that extra one somewhere safe. Hopefully you won't ever need it but if you do . . . So, definitely, yes buy this. I don't think I've ever given this enthusiastic a review on anything else I've bought in the past.

This bedsheet keeper works very well. I can also easily put it on and change the sheets all by myself. I would recommended this product to anyone who struggles with sheets popping off at night. It’s well worth the money. The quality is very high, and definitely not cheaply made like other brands. It’s worth it to go with the name brand!

I don’t normally leave reviews but these are fab , I brought a new mattress and the sheets keep coming off and it’s been driving me mad , tried the elastic ones and they broke , these are amazing , fitted easily and the sheets keep coming hasn’t budged all night , expensive but worth the money

Good product. Keep bedsheet in place. Issue - Need to fix daily on corners. It gets pulled up if you stretch bedsheet too much.

Saw the ad for these and I have to admit I was super skeptical, but I took a chance anyway. And guess what....they absolutely work as advertised. Could not be happier with the purchase. We've had these on the bed now for a couple of weeks and the sheets are exactly where we put them on day one! Not moved at all.

Excellent product

If you love tight sheets and live with a partner who tosses, turns, and yanks them out every night—these sheet holders are a total game changer! Pros: Keeps sheets tight: I like my sheets tucked in crisp and snug, but my spouse has a habit of pulling them loose and popping the corners off. Since using these, the sheets stay exactly where I want them. No more corner chaos: What used to be a nightly battle of bed corners flying off is now a thing of the past. These straps lock those bad boys into place and don’t budge! Easy to use: The plastic holder easily slips in and out of the corner piece, so changing the sheets isn’t a hassle—you don’t have to fight with it every time. One-time install: It’s quick to set up, and once installed, you’re good to go with minimal fuss moving forward. Way better than bungee straps: I’ve tried the traditional bed sheet bungee straps, and these are so much easier to install, adjust, and maintain. No lifting the whole mattress or wrestling with awkward clips. Bottom Line: If you're tired of waking up to a messy bed or battling over tucked vs. untucked sheets, these sheet holders are a simple and effective solution. Tight sheets, happy sleep—no more popped corners!
