Did you read my other post about pillows? I considered buying one filled with green bean husks or tea leaves but in the end plumped for a memory foam pillow. It’s treating me very well. There are a number around the same price -sub 1000NT but I got a USA made one that was 999NT, because it looked the best.
It has contours - you can either use it with the flatter contour under your neck or the higher one. I sometimes swap round during the night if I want to lie on my side or front for example. I haven’t had any neck aches since I got it.
It’s called ‘Smooth’ and the biggest lettering on the box says ‘U.S.A. NEW UNIQUE MATERIAL
PRESSURE RELIEVING NECK PILLOW’.
You wanted to know where purchased - it was in RT-Mart (a sister store to Damaijia/Save & Safe) on Jinhuabei Lu, Taichung. But I’m sure you can find the same brand in any big store such as Carrefour.
PM me if you have any questions.
PS With the computer work, are you using one of those office chairs on castors? I would recommend ditching it and using a standard chair with four legs, but either propping up the back legs slightly or getting hold of a cushion which slopes slightly forward for the optimum posture. My old Alexander Technique teacher had a friend who made such sloping cushions. You should also consider using a keyboard such as Microsoft’s ‘Natural Keyboard’, which divides the main kepad into two sections, and contours the whole thing so it’s a lot more comfortable (it’s best if you can touch-type). That helps your arms but also your whole upper body. In addition you should be taking short breaks from time to time, doing arm rotation and other exercises both while seated and not, and also doing eye exercises.
