The concept behind the Loftmat is excellent, and I do think it delivers on its intended purpose. The cushioned surface provides noticeably more comfort when using a vertical mouse, particularly when the bony part of my wrist rests against the surface or my forearm occasionally rests against it while mousing.
Unfortunately, the practical design and durability leave something to be desired.
On my very first day using it, I accidentally spilled something on the surface. While trying to clean it, I discovered that the underlying structural layer is surprisingly thin and flexible, almost like cardboard or chipboard. Applying pressure to clean the cushioned surface caused that underlying layer to bend, leaving one corner of the mouse pad permanently raised rather than sitting flat against my desk.
Cleaning the surface itself was also frustrating. The fabric retained fuzz from the towel I used, leaving lint embedded in the material that I have not been able to entirely remove.
Now I'm left with a mouse pad that no longer sits flat, which interferes with its functionality slightly and creates an additional nuisance on my desk. The raised corner can catch on things as I move them across the surface, potentially causing another spill.
I really like the concept behind this product, and the cushioning does make a difference in comfort. However, a mouse pad is an everyday use product that should be able to withstand an occasional spill and be able to be reasonable cleaned without becoming permanently deformed. A more rigid, water-resistant foundation and an easier to clean surface would greatly improve the product IMHO.
