My mom has been ill and confined to her recliner for sleeping. She developed pressure sores and was in a great deal of pain. We needed to treat the sores and I researched how to prevent in first place and found that genuine sheepskin helps. I had no idea this was a thing. I ordered this for her recliner and a seat one for the car. She loves this. She said she could feel an immediate difference in sitting for so long that she didn't need to shift constantly. I don't understand the mechanics behind why this works but I'm grateful for something natural and affordable like this to offer such relief.

The white one seems softer than the cream one!? Seems like great value for your money for a single pelt, the seller and product didn’t seem sketchy at all.
