I have a travel puzzle board from Lavievert that I found on Amazon. I tried a couple others & wasn’t happy with them. This one I like very much. The board inside is removable & has a non slip surface. The cover of the case is padded on one side. The weight of the padding helps keep the pieces from sliding too much when you have to tilt the whole thing to get up the stairs & through doorways. I can tell you from experience that nothing seems to perfectly hold an incompleted puzzle in place if you turn it completely vertical. Everything I’ve tried still allows the pieces to move. But the Lavievert case holds it pretty well. I get the best results if I carry the board tilted about 45 degrees on an angle, as opposed to totally vertical. Here’s a link to the board I have: Lavievert Travel Puzzle Board
