I have had a few different orders from Wayfair - furniture and a pillow - the quality has been very, very good, so I am really disappointed with this product.
It's 50% polyester/cotton, but is quite an open weave so the texture is rough and the material is transparent. I've not been able to use this yet, as I need some fabric conditioner to try and soften the material... I would not recommend this duvet cover.
