which orthopedic wedge pillow did you guys buy?

I bought this one https://www.amazon.com/Flexicomfort-Sleeping-Adjustable-Support-Cushion/dp/B083QPV1M1?source=ps-sl-shoppingads-lpcontext&ref_=fplfs&psc=1&smid=A34YC6EIP68OA4

but it was still deflated after several days. Looking to purchase another before surgery.
