Worked perfectly
Did exacltly what we needed. Let me compress a CA King into a roll and load it in the back of a minivan

Nothing happened
I’ve vacuumed sealed a mattress before and know that the process is fairly simple. The most difficult part is sealing the bag the make sure no air leaks and the whole process can work, which is why I chose this product. The double zip lock sealing feature seemed great. When I got it on the mattress, it sealed easily for me and I thought this would be an easy process, but it wasn’t and I still can’t figure out why. The cap part of the product didn’t do anything at all when I started trying to vacuum seal. I switched to trying to stick the vacuum in through the zip lock and it appeared to work at first but never deflated more than just a little. I tried both options repeatedly and couldn’t get the mattress to go down at all. After several frustrating attempts, I used a different standard mattress bag on the inside of this one and got it to deflate and then sealed the whole thing with the zip lock bag. I was able to roll my mattress and clasp it with the provided straps, but after two days, the mattress reflated and the clasps snapped off. Ultimately, I could not get this to do what I needed it to do at all.
Easy and simple
We used two of the vacuum sealing bags and glad we did as first one had a tiny hiss at zipper so taped it up but did it inside a second one for extra sealing. Then also wrapped it in heavy duty painters plastic and taped and banded with the straps. It was heavy but shipped east coast to west coast for $210 in 4 days. Relief!!
Vacuum will hold for about 3 days.
Overall, this was a great product. The vacuum was fine for about 2 days. On the 3rd day of travel we could visibly see the mattress swelling. However, it did it’s just admirably and we were able to get it into the new apartment *mostly* vacuumed. Totally worth the money.
Worked Great!
Just bought this to store my memory foam mattress from my old apartment. Worked great! Didn’t take long to deflate. Only thing I have to criticize is the opening where you attach the vacuum nozzle. It didn’t attach that securely, the attachment is based on suction and there wasn’t anything there to keep it secure. I ended up once or twice having to put the nozzle back on the attachment site. But even so, it worked pretty well, no air leaked, so I really don’t have any complaints. Overall great product. Hope it lasts!
