I suffer from chronic stenosis in the lower back and sleep was impossible even on my trusted comfy mattress. I read good reviews and ordered the Panda topper. This has relieved the pressure on my lower back because it holds my middle and upper back. Plus I can sleep on my side without getting dead arm. So wonderful I purchased two Panda Bamboo pillows and now my neck pain is also eased. I cant wait to go to bed every night instead of dreading it. I sleep so much more deeply. Thankyou Panda. I am telling all my Yoga students 🦝💚
