First let me say I've been buying from Amazon about 6 years, I'm not one to write reviews. Maybe in that time I've done four at best. I have an extremely thick mattress with a thick mattress pad on top. It's impossible to find sheets. And when I do they're either too small or too large. The large ones are just a wrinkled up saggy mess after sleeping in the bed. The small ones as you can imagine pop off the corners. Every morning I would get up and have a serious conversation with this bed. It would make me so mad, break my nails and took forever to make. I have tried a couple other gadgets to tighten up your sheets but they didn't work very well. Then I saw this. It was a little bit expensive but of course you can return it. My husband had to initially help me put it on. All I have to say is WOW, ABSOLUTELY AMAZING.!!!!!! IT TRULY IS A GODSEND. My sheets are still tight, no corners have popped off. They were on there for 7 days before I changed the sheets. They never moved. It was like the day I put them on. When you open the box, it says this will be your next favorite thing. They weren't wrong.This thing is amazing, worth every single penny I paid for it. The cool thing they're generic to any bed size. And it comes with this little gadget to tuck in your sides or whatever. That thing is so simple, but work's so well especially breaking nails I wish I would have thought of it.... I really can't say enough about this product, I will get them for every bed I have. If you experience the same problems I do you got to try these. You'll be so happy you did, and it will become YOUR favorite thing. Thanks to whoever created this. Read more

Awesome! They say you're to start your day right by spreading your bed. But life can be hard and busy. This keeps the sheets tight so you don't feel that guilt that you're starting the day off by slacking off or procrastinating. You get back home to a welcoming, bed and go to sleep after a full day with no regrets. Pros: easy install, fairly clandestine. There is an extra transparent piece in the kit. Con: Would buy for all the beds in my home but it's a bit pricey. But the function and quality is top notch. It's worth saving up for! Read more

Ever wake up and wonder “what is this wad under me?” and realize it’s the fitted sheet that came unhitched and now you’re lying on the mattress cover?!? We have split adjustable California king. Those things are awesome for sleeping and preventing reflux but notorious for sheet slipping! I have been using a web of sheet suspenders to hold the fitted sheets on but what a PITA to put on and take off!! Saw these contraptions and thought the price was a bit steep but my time and peace of mind were worth it if they worked. Ordered one set to use on the interior of the two XL twin mattresses just in case. Well, gloriaski!!! They Do work!!! Plus they’re sturdy and easy to use. Ordering another set to have on all 8 corners. Don’t mind paying for innovation and quality!!! Read more

Perfect for holding our sheets down! We have been so frustrated the last few months as our sheets constantly pop off and we used these last night for the first time and everything is exactly as it was when we went to bed. They are super secure and easy to assemble. Will be buying for gifts for my in laws! Read more

Works well, sheets have only rolled up a bit once but still did not come off the mattress as often as it did before, pretty much never now. Great product! Read more

Works very well unless you are a large person! On my wife’s side she said that she doesn’t have any problem with it! On my side of the bed, the plastic sheet restrainer at the head of the bed, tends to pull out from under the mattress and gradually side up and out! They can solve this problem in either one of two ways either adding about 6 inches to the bottom flat panel of your device or build and market a separate device with at least two extra large panels that would have 6 to 8 inch longer bottom panels for heavy or obese customers Read more

I’ve tried countless devices to keep my sheets tucked under my mattress and some were abject failures, others kinda worked but were unworkably difficult to use, others kept the sheets tucked but not flat after being slept on (think those giant elastic bands). So, after much despair and desperation, I decided to invest in the ZlumberLock. Pricey? Yes. But does it do what they say it will do? Absolutely. I ordered a set for a Queen-Sized mattress and was just delighted when I found the ZlumberLock so easy to install. The ZlumberLocks consist of 4 corner-pieces and 5 (one extra) sliders. Simply put a corner-piece in each corner of the mattress, put the sheet(s) over it and then insert the slider into the groove. So easy to do and only requires one person to make the bed. It tightly locks the fitted sheet in position and even can lock the bottom of the top sheet tightly in place. And the fitted sheets do not move, do not bunch, do not wrinkle. They are flat when I get in bed, flat when I sleep in bed and flat when I get out of bed in the morning. So, do I recommend? Resoundingly so! I have a family member who couldn’t make a bed properly if he were paid a thousand bucks to do so. Well, he’s a Full-Size mattress guy and I ordered a set of ZlumberLocks for him. To complicate matters, he will only sleep in flannel sheets. The added thickness of the flannel does make it a teeny bit more challenging to use the ZlumberLocks but it was still not terribly difficult for him to insert the slider into the corner-piece and successfully make the bed. And, voila, the flannels lie flat and taut. The ZlumberLocks are mostly invisible. They seem durable. The sliders are very flexible but one does wonder if they might snap in time. But they haven’t given any indication of that happening yet. And the ZlumberLock people do include one spare slider. So, if you’ve reached critical mass with recalcitrant bed sheets, give ZlumberLock a try. Read more

Wish I had of known about these years ago. Super easy to use. Our sheets haven’t moved once. Quality is excellent so these will last forever. Read more
