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

I am impressed with how well these hold two layers, the mattress cover and sheets, so well. I stay in my tra el trailer during the winter and changing sheets is hard on those beds, so when the sheets continuously come untucked, it is incredibly frustrating. With this system, I no longer need to worry about them coming loose. They are big enough to cover each corner and the band was fairly easy to snap in place once the sheet corner was tight. This set came with a tucking paddle to help push sheets in the hard to tuck areas, an instruction booklet, though watching the video on Amazon was enough for me, and they also included a sleep mask. Well worth the price for me!!

I'm very judicious with my reviews. Our sheets were lifting multiple times per week; however, since I purchased these beauties, 0 times per week - not 1 time since!!! LOVE THESE! WELL WORTH THE $$$ MONEY $$$!

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.

They work great. Well worth the buy. Sheets are stay right where they should and it’s easy to reinstall after a change.

Work as advertise. Only had them for a few weeks, but they work perfect. No more bottom sheet pulling off every night. Not cheap, but you get what you pay for and these are very high quality. Don't hesitate, if you are having issue with you sheets staying put, then just buy these.

These things are very good. They holds in place very well with one major caveat. Platform beds... If you have a bed frame like my wife and I that is. Our platform bed has no raised edges. The edges of mattresses don't have much downward pressure. This means once in a while they can pop out and flip up onto the bed. I solved this using two flat bungee cords to under the mattress to keep them in place. 4 stars for being almost perfect

This is the real deal. We had earlier accidentally bought a knock off version, but the quality difference is night and day, and the same goes for the functionality. The knock of worked a little, but this original one is just doop proof, it is also sturdier while nicer to my sheets. The base is a single piece and large enough to not slip out of the mattress, the strips are noticeably thicker, yet easy enough to put in place, and without edges that may damage sheets. Also, after market support has been amazing, the strips had not made it in the box, and without problems some replacements were shipped. Thanks a lot!

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.
