I bought a cushion for my lower back pain and sciatica and it doesn’t cure the pain but it gives so much relief I highly recommend this product to any one needing support for back pain , funny thing I went to Cairns and the ABnB had a mattress topped and I had the best sleep I’ve had in years so I ended up ordering one of them also which I’m eagerly waiting delivery, if you have and nagging pain or even if your looking for a very comfortable sleep do yourself a favour , I promise you will never regret it Thank you.
