Storage Logic (King/Cal-King) Foam Mattress Vacuum Bag For Moving/ -Compress By 80%, Seal Bag, Leakproof & Sealable Mattress, Includes Straps

This was a hope and a prayer purchase because we were moving a long distance with our memory foam in weather, and we hit all the weather rain, snow, everything in that trip. This mattress cover worked GREAT for that move, Everything was dry and easy to transport. It worked so well we used it to bring our bed camping in a later trips and it is still holding strong, no leaks causing reinflation during transport and I forsee us using it many more times because the bag is showing no signs of breakdown as of yet. Now we did read the instructions and we did wrap the outside of the rolled up mattress during transport as it recommended. I have a queen memory foam but I purchased a king bag for ease of use and it works well even for an undersized mattress, I didn't need to buy the size up as the sizing looks to work just fine for the size intended, but I'm happy I did buy the size up it just makes it easier for us. A regular vacuum works just fine no shop vacuum required. The valve is awesome if you pull the vacuum off during deflation at anytime it doesn't allow reinflation. I did end up using the first bag I bought ( queen size) to vacuum seal our giant bear(Costco giant teddy bear) for the same move it worked so well. For us it was a one-person job putting the bag on the mattress and even vacuum sealing it down, rolling it up and putting the straps on to hold the roll was a two-person job. And in sock feet as per instructions walking slowly on the bag did help deflate it more than the vacuum could as it was getting vacuumed down. It didn't cause any damage to the bag walking on it, a note we didn't start stepping on it until the vacuum had the mattress almost all the way deflated. I absolutely recommend and have recommended to friends, I mean who couldn't use a giant vacuum seal bag LOL

Bought a bigger size since my mattress is 160 cm wide but thin. Could probably have gone with the smaller size as well. Worked really well so far. Hope I won't experience any air leaks.

This bag works quite well, as long as you have the right vacuum for it! I have purchased and used this exact product twice so far, because I end up puncturing it every time I use it (more on this later). The first time I used it, I tried using my regular household vacuum cleaner (Miele canister vac). It worked a little bit, but the vacuum quickly overheated and shut off. Most household vacuums aren't meant to operate at maximum suction without a lot of air flowing through them (because they rely on the incoming air to cool the motor). The second time I used this bag, I used a large shop-vac (Rigid brand vacuum). This worked a LOT better and didn't suffer any overheating issues. If you want an even better vacuum, I have some more info later on. For most people, using a standard shop-vac will do the job nicely. Once you have pulled the vacuum, fold the mattress over and strap it up. Having a second person to help here is very useful -- one person sitting on the mattress to keep it folded while another person straps it worked very well. I used the included straps to hold it in half, then used some ratcheting straps to tighten it up even further. Note that if you use ratchet straps, put a piece of cardboard or something like that between the metal ratchet body and the plastic bag to keep from puncturing the plastic. The attached image is of a Purple 3 mattress under full compression. I think the compression is just as good as the factory does, but I didn't have enough leverage to actually "roll" up the mattress and could only fold it in half. Its still plenty small enough to fit in the back of a normal station wagon/hatch/SUV. Once your mattress is vacuumed and folded, you really should add some extra protection. You can wrap the mattress in mover's plastic wrap, or find some other heavy duty plastic/tarp to wrap this in. The vacuum bag punctures VERY easily. This happened BOTH times I tried moving with this. It's not the end of the world, as long as your straps are tight -- the straps will keep the mattress MOSTLY contained even if the vacuum is lost, but it will be a LOT more difficult to move around without the vacuum intact. Note that I punctured this even though I was trying to be very careful. I was moving my mattress with a helper down a short walkway between my door and the car. The mattress was very heavy, so we stopped once to put the mattress down and take a quick break. The bag touched a grain of sand on my walkway (yes, just a grain of sand), and this caused a minute puncture. It was enough that I could hear it leaking, but I couldn't stop the leak with duct tape or anything like that because of all the creases in the plastic. Within 2 hrs, the mattress bag vacuum was completely lost. So if you want the ultimate vacuum, I had good results using a four-stage diaphragm pump with a shop-vac as a roughing vacuum. Most people won't have access to this equipment, and probably won't need this level of vacuum to be honest. My shop-vac took the vacuum down to about 650 torr. I was able to attach a diaphragm pump using an NW25 fitting. If you remove and use just the O ring from an NW25 centering ring, it will fit over the inlet port nicely and creates a good seal once a vacuum is established (see photo for more info). I took it down to 40 torr and said "good enough" there. The majority of the compression had already happened with the shop-vac -- the difference between 650 and 40 torr was noticeable, but not enormous.

kaliteli çok beğendim teşekkürler

Es un invento maravilloso que realmente funciona, el problema es que no pone el tamaño en centímetros. Lo he tenido que cambiar porque mi colchón es de 135 y con todo lo que sobra al envolver es molesto, abulta y se puede romper, pero en su tamaño ajustado es fantástico
