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

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!

we tried several other options, including the 3 legged bungie straps on each corner. These seem to work out much better and i have put them to the test in the last week. With a sore leg, i have been dragging myself across the bed the the corners are staying put finally! These are a little tricky to put the strip in, but once you do it a time or two, it is pretty easy. I found it best to start on the one side, and when you get to the corner, push the strap around the corner and into the other side. The sheet gets caught a little, but you can figure it out! Found it hard to push the strap past the corner, and then try to bend it down and into the other side. Little pricey, but after spending money on options that couldn't keep the corners in place, this was worth it.

This device actually works! I got this because we added a 3” foam mattress topper and now our sheets don’t fit. It grips the sheets at the corners, even though the sheets don’t quite reach the bottom of the mattress. It stayed in place for the entire week, then was easily removed to replace with clean sheets. It also worked on another set of sheets that were even tighter. For tight sheets the installation each week is a bit challenging, but if the sheets fit properly it would be easy. No other solution works for my situation. Elastic bands are a much bigger hassle and can’t hold as well. I have had NO SLIPPAGE since I installed these corners. The only possible issue is that our mattress is bulgy on the sides, so the corners are not 90degrees, so the curved corner pieces don’t fit well, but they work anyway! Again, if you have a normal mattress with normal corners it would not be an issue. And sheets that fit would be easy installation. Also, it came with a paddle to help tuck in your blankets while making the bed. Not needed for using the sheet holders, but super helpful for bed making.

We just put this on our bed today. I am so impressed by the sturdiness and quality of these sheet holders. We were using the elastic band with clips. You had to turn the sheet inside out and space out the clips. Then you had to run the entire elastic band around the bed while tucking it under our heavy mattress. It was such a pain and took forever to get it done. I saw this one and decided to give it a try. I’m so glad I did! We just slid the corner pieces under the bed then pulled the sheet over them. We slid the strips in the indented part and we were done. This is a complete set with a lot of bonuses including a nice sleep mask and a large piece that helps to tuck the sheets under the mattress. It literally took us five minutes to finish and the sheets aren’t going anywhere. I truly can’t recommend this system more. Buy this one instead of the imitation ones.

The ZumberLock Sheet Holders are an absolute wonder. I have a CalKing adjustable spilt mattress and the sheet holders work perfectly as they are only inserted on the outer 4 corners of the mattress. The corner inserts slide easily under the mattress corners and stay in place until you take them out. I put both the fitted sheet and flat sheet over the corner holders then slide the included plastic strip in the grove on the corner holder. Very very easy. Everything stays in place all night. I end up having sheets all night and I wake up comfy cozy. In the summer when I use a thin blanket I can even include it under the plastic strip with the sheets. I have to work a little bit at getting the strip in the holder grove with the added blanket but it works great, the plastic strip is very strong and flexible, strong enough to take the bend. So simple. I love the ZumberLock sheet holders.

So this product is great, it works well so far and is easy to install the only complaint I have is that the plastic bars that slide over the sheet to lock it in place have that thin plastic film on them on BOTH sides that is really hard to get off and genuinely so unnecessary and just extra trash. That’s the only thing I’d change but other than that definitely get!

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 works wonderful! Our upper corners were always coming loose but these hold them in place! Worth the money!

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!
