Wool bedding is generally hypoallergenic and less likely to cause allergies. Wool fibres have a natural resistance to dust mites, mould, and mildew, which are common triggers for allergies. However, individual sensitivities can vary, and some people may still have allergic reactions to the larger fibres of wool, or sometimes the tiny amount of residual lanolin on the fibres. If you have known wool allergies or sensitivities, it's advisable to test your tolerance or consider alternative bedding options.
