I ordered a classic woollen pillow for my husband's birthday and the order arrived in good time (2 or 3 days). He is really pleased with it - he's always been a hot / sweaty sleeper and for the first few nights on this pillow, his head didn't sweat at all and we were really surprised and impressed. Then the weather got really hot and he has since sweated on it, and when damp it gives off a bit of a 'wet wool' smell which isn't so great. But overall it's an improvement, and when we can afford to, we will get the woollen mattress topper and a woollen duvet which I expect will help further.
