Hi Raiza. We are so sorry to hear your chain broke. To be honest, we advise people not to wear jewellery in bed, as it is not designed to be sturdy enough if it gets caught or pulled on something by accident. However, our chains our covered by a lifetime warranty against production issues, so we will happily replace it for you, in case it was faulty. We will post it out to you in Switzerland today. Thank you for letting us know x
