I was looking for something that I could use for my wireless mouse. After looking for days, with almost zero results ( i was looking for just a flat surface) I settled for this one. Not only were the others either prohibitively expensive, but most would not fit the 14 inch armrest width. I decided to give this one a try. I figured if it didn't work for my purposes I could give it to my husband to use for his coffee cup (he'd already left a ring on the arm of the sofa - ugh). WHAT A FIND! Not only does my mouse work wonderfully on its surface, but the "leg bands" adjust to fit the extremely wide arms so it doesn't slide off. The tray-like design of the table not only keeps my mouse "corralled," I can leave my glasses there too without fear they will fall off. The side pockets are just a bonus for me - i use them to keep computer peripherals handy. Loved it so much we got another one, so my husband could have a better place for his coffee cup AND keep track of the remotes! GREAT VALUE FOR THE MONEY!
