This looks like mostly the same thing except the grid itself was rotated 45° from what I had. I did look into alibaba shortly after I made my bed when I was discussing this with a friend. The limitations of alibaba I found at the time were:
1. The HxW dimensions didn't necessarily match anything I wanted well. I needed four toppers to make the original mattress and offhand it looks like I could probably make it with four gel sheets from alibaba but the cuts would be more complicated to lay out and attach.
2. The thickness was listed at 4cm vs the 2" thickness of the buckling gel from intellibed. 2" is about 5cm.
3. Despite the intellibed toppers coming with a useless amount of foam, it wasn't actually any cheaper per square inch to order the gel from alibaba at the time, not that either was especially cheap. Numbers may have changed by now.
