I purchased a daybed (Samoa) from Sieger through Ostermann. Unfortunately, the daybed had both technical and cosmetic defects. To this day, I am still waiting for a response from Sieger / Constancy GmbH regarding my complaint. I am very disappointed with the service and product quality provided by Constancy GmbH. What a shame.
