I'm searching for solutions to the discomfort I feel when sleeping on my side. Two pregnant friends suggested a memory foam mattress topper, but the two things holding me back are the price and the potential emission of stinky/harmful VOCs from the foam. (I wasn't aware of that potential problem with memory foam, but a third pregnant friend was pretty adamant in NOT getting a topper for this exact reason so who knows.) Anyway - do you have one, and does it help with any hip pain you might feel when sleeping at night? Brand recommendations?
