Check the weight! Bought a classic light wool duvet, double. The double is supposed to weigh 2.2kg in total. At 250grams per square meter there should have been 1kg of wool. It felt too light and I could see that the wool was very unevenly spread with lots of gaps. Took it to the post office to be digitally weighed, it was 1.8kg - 400g of wool missing. Woolroom asked for a batch number and checked their stock which they said all weighed in correctly so they asked me to send it back to check, and they agreed it was underweight and sent me a replacement. The replacement is much better but I weighed it out of curiosity and it was 2.17kg which was acceptable. Fair customer service. Postage refunded no problem. The duvet is of very decent quality for the price but Woolroom could do with better quality control. I recommend customers check the weight of their duvets as I've noticed some reviews stating that duvets were lighter than expected. Wool duvet has definitely improved sleep by helping to regulate temperature.
