In an awful mood this morning after finding someone forgot to roll up our memory foam play mat last night before opening out the sofa bed. Has anyone any tips for getting furniture dents out of these mats? Please no comments about how over priced or foolish it is to own these mats. It was a rare new and pricey purchase and we have no regrets and love the mat and how it looks, so really hoping there is something we can do because we won’t be replacing it.
