This might be the perfect comfort mod for those who are big fans of lying down consuming videos/playing VRchat on Quest 3 & 3S...

Simple and effectively improves stock strap comfort.
No knob on the rear so very good for lying down.
The pad is soft and works like a pillow on the rear 
Self-weighted about 200g, which is good for front-rear weight balance.
Anti-slip celled silicon material, which is grippy and improves the stability of the headset.
