I'm just wondering if King size means something different in China?"

"I’ve bought at least half a dozen mattress covers over the years, and this one is the best! No noise, fits well, and is soft. The zipper covers the entire mattress. Trust me, don’t waste money on cheap options that slip off and break quickly. A little extra investment now saves you from spending more later. Perfect for long-term protection against spills and pests!"

"I have a thick mattress, and this cover fits snugly without being tight. The zipped design keeps everything in place, which is great because my mattress is slippery. I used to struggle with straps that would come loose, but this cover has a nice thin terry cloth top that prevents that. Plus, it has a good waterproof layer and is not noisy or hot!"
