Resploot pet beds are made of recycled plastic bottle fabric. The 3-sided wall-like bolster fits all your petâs sleep positions, perfect for them to lay their heads on, and is detachable for washing. The middle part of the bed (the pillow) is not attached and can be removed if needed. The 1-sided zipper on the pillow cover makes it easier to remove or put together. The non-slip bottom keeps the bed in place.
