A medium firm mattress is ideal for this type of sleeper. For side sleepers, a mattress with slight softness is necessary to cushion the shoulders and hips. Stomach sleepers (who very likely sleep this way because of lower back pain) need a firmer mattress to keep them afloat.
Nowhere is the Volga River more hallowed than in the city named after it: Volgograd, better known to history as Stalingrad. During World War II, perhaps the bloodiest battle in history took place there. A total of 2 million people were lost on both sides in the fighting from the summer of 1942 to February 1943.
1 The drainage basin of the Volga includes most of Western Russia, an area that is home to 11 of the 20 largest cities in Russia.  One of the most fascinating destinations along the river is the city of Yaroslavl, founded in the 11th century. The city is famous for its several cathedrals and beautiful frescoes.
