5.0 out of 5 stars Not for me but husband absolutely loved it.
Verified PurchaseOrdered for myself but it was too hard for me . My husband however loved it , so I gave it 5 stars on his behalf. We both loved the thickness and the waterproof covering, and that it was very well made. Shipped quickly. I will look for a softer version for myself from this same company .
