I like the sustainability and of course the look of Antler & Co.'s antlers, but not the price tag so much. Another cruelty-free company is Peak Antlers, but their website doesn't have the minimalist, Scandinavian esthetic of Antler & Co.'s, but more of a Christmas sweater one.
Here are some more antler ideas:
An antler chandelier that doesn't look like it belongs in a hunting lodge; and it's actually wrought iron and resin imitating antlers.
This one had that headboard I liked too, but so not cruelty-free, unfortunately
And lastly, something less conventional, but so so cute
