I am a recently Disabled Veteran with Peripheral Neuropathy as one of many health issues, where hands are tingly, fall asleep/pain, especially if typing on laptop for a while and ridge of laptop aggrivates this condition and thought I'd try this as am already very familar with memory foam for my mattress and one chair, (bought on OS as well). This works like a DREAM! The fact that you can bend it to conform to your needs is great, with one half of it a bit wider to accomodate your dominate hand. Albeit it is about three inches longer on each side of my laptop but have found that to be an asset when utilizing numeric keyboard, etc. It also has a non-slip backing so it indeed stays-put! I am SO pleased with this that after this review, am ordering one for my mother as part of her Christmas, due to her carpol tunnel; and yes, I shop through the year for Christmas to not only avoid the crazies and demonic strollers, but also to keep the spirit of Christmas alive and well through the whole year as the core meaning of Christmas should be in our hearts everyday! A great buy and thanks again OS for a great price and fast shipping!
