Service Rating : Excellent service. Cushion was shipped quickly and arrived quickly.

Product : I bought the Diffuser Cushion to help with Sciatica. I mainly use it on my office chair as sitting on my ergonomic office chair often makes my Sciatica worse. It has definitely helped relieve the pain. The cushion is slightly firm when you first sit on it but after a very short amount of time, it starts to soften and mould to your shape (I'm 56kg so light weight).
Definitely recommend! It was posted quickly too.
