I have been influenced to splurge on wool pillows (have been considering this for some time) as given the amount of time I spend in bed, I think it's a worthwhile investment. I've seen complaints about 'shrinkflation' and poor quality standards (notably multi-pack knickers) and definitely think that applies to pillows. I'm also still miffed about having recently had to replace a John Lewis mattress after 5 years. The product description for it now states that it is not recommended ’for regular use', pretty sure that wasn't there when I bought it originally - was hyper-vigilant about the new one.
If anyone is feeling wool-curious, the Woolroom offers 30 or 60 day trials (not sponsored, not an ad)
