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

This is an amazing item. I twist and turn constantly at night making this a must have. The sheets stay secured to the holders no matter what I do. They work great with a California King mattress. They are easy to install and are an amazing product.

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.

These locks work great! Our sheet has yet to pop off (about a week later) and thats with 3 kids constantly jumping/wrestling on it. I highly recommend, the installation was super easy as well. I was hesitant because of the price but it has been worth every penny!

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.

We have struggled with fitted sheets actually fitting for a long time. This is a game changer. Easy to install and holds the sheets in place as described. It is made of durable materials and seems as if it will last a long time. Our sheets fit so much better! Recommend ⭐️

I've been wanting something like this device for a while...it works just as it says...easy to install and came well packaged and presented....I do not regret buying it...was a bit pricey but it works and the quality is there.

This sheet holder is an absolute game-changer. I was so tired of waking up with the corners of my fitted sheet popping off the mattress, but this completely solved the problem. The heavy-duty straps are incredibly secure and durable, and the universal fit works perfectly on my mattress. What I love most is the easy, one-time installation, once you set it up, you don't have to keep messing with it every time you change the bedding. It keeps everything looking neat, tight, and securely in place all night long. If you're tired of loose sheets, this is worth every penny. Highly recommend!

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.

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

These are amazing keeps the sheets on better than the elastic clip on

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.

Genuinely works, easy install, actually does keep the sheet tight on my annoying Tempur mattress that no sheet would stay on! Very pleased..

Excellent product
