We’ve now stayed in three hotels in three Russian cities and, so far, the beds in all of them leave a lot to be desired. As soon as you lay on the mattresses, you can feel the springs pressing against your body. The mattresses are not old. In fact, the mattress in the current hotel looks to be brand new, but they don’t seem to be made with any padding above the springs. And they are not very comfortable!
Our camping mattresses are much more comfortable, but then I had them custom made. They have 3 inches of memory foam above 3 inches of standard upholstery foam. Together with our memory foam pillows, we sleep better in the tent than we do in the hotels!
