Animal product origin and guarantee of ethical standards?

Hi, Please can you provide details of how you ethically source the wool and horse products for your products. We are keen on the mattress (Artisan Bespoke) but equally aware of terrible conditions animals can be kept or slaughtered for the the use of their by-products for manufacturing. Ideally, we are looking for a statement on how you ethically source and ensure the animals are not being mistreated or slaughtered for the product.
