    We sent our layers to two people who sleep hot. Here is what they said

    I’m definitely one of those people who can go from ‘I’m freezing’ to ‘why is it so warm in here?’ in about five minutes. Anything that helps keep the bed feeling lighter and cooler gets my vote.

    After spending all day training, the last thing I want is to climb into bed and feel like I’m still overheating. I’m all for anything that makes the bed feel a bit lighter and more breathable.

      Definitely the final touch to the bed I was looking for, but the fabric feel might not be for everyone

      Like the clean finish and lack of unnecessary detail that other brands have, good for minimalist rooms

      I was told there was a mismatch in deliveries that delayed my order which didn't help in getting it to my relative on time for her birthday. Regardless she was very happy with the product, thanks for solving the issue promptly

      Their bedding works with the different room styles we have at home, side note: I love home décor. But check the size options carefully before ordering
