Sleeping on your side demands a mattress that balances pressure relief with spinal alignment. Most Americans (between half and three-quarters, by some estimates) favor side sleeping, making this a critical consideration for many. The wrong mattress can lead to back pain, hip strain, and general discomfort. This guide, compiled with input from sleep science coach Julia Forbes and veteran tester Martin Cizmar, breaks down the top picks for 2025, tested over weeks of real-world use.
Why Side-Sleeper Mattresses Matter
Side sleeping puts unique stress on your body. Without adequate cushioning for hips and shoulders, pressure builds up, causing aches. Conversely, insufficient lumbar support lets your spine sink, misaligning your back. The ideal mattress for side sleepers must provide both: enough give to relieve pressure and enough firmness to maintain proper spinal alignment.
Top Picks for 2025
The following mattresses were selected based on rigorous testing, focusing on pressure relief, lumbar support, and overall comfort.
Nolah Evolution: Best Overall
The Nolah Evolution stands out for its targeted pressure relief and support. The luxury firm option keeps the spine aligned while cushioning hips and shoulders. Zoned AirFoam and pocketed coils provide a balance between comfort and stability. Reviewer Julia Forbes notes, “The pillow top hugged my body, but the bed still felt noticeably firmer… perfect for side sleepers needing something softer for hip or shoulder pain.”

The Helix Midnight Luxe is a perennial favorite, and for good reason. Its dense foam layer in the torso area provides exceptional spinal alignment, reducing back pain. The ErgoAlign feature (an upcharge) adds even more support.

Copper-infused foam adds cooling, while zoned coils further support the lumbar region.
