Pregnancy Sleep Tips by Trimester
First Trimester (Weeks 1–12)
Sleep position is less critical — any comfortable position works. Focus on managing nausea and fatigue. Consider a mattress with good motion isolation if nausea causes frequent position changes.
Second Trimester (Weeks 13–26)
Begin training yourself to sleep on your left side. A medium-soft mattress (4–5.5 firmness) helps cushion your growing belly. A pregnancy pillow combined with a good mattress provides optimal support.
Third Trimester (Weeks 27–40)
Left-side sleeping is most important now. You'll need maximum hip and shoulder pressure relief, strong cooling (body temperature peaks), and a responsive surface for frequent repositioning. This is when mattress quality matters most.
