The Sit Cushion item on Marketplace is a pillow which you can place in world and sit your avatar on. You can sit on it by clicking it in Desktop Mode or by using the Teleport system with your VR hand controllers.
There are reports of users avatars automatically standing up after using the teleporter to sit upon it. There have also been reports of desktop users being seated at unusual angles.
Please fix so that the avatar is always seated upright and it works as expected.
Current version here:
Resubmit to Marketplace once it is working as expected.
