Best Mattresses for Side Sleepers in 2025: Expert Reviews, Comparisons & Buying Guide End the Tossing and Turning

Updated for 2025

— Side sleepers need the right balance of pressure relief, spinal alignment, and responsive support. This guide compares three of the best mattresses available in North America and helps you choose your perfect match.

Why Side Sleepers Need a Specialized Mattress

Over 60% of adults prefer sleeping on their side, but this position adds pressure to the shoulders and hips. The ideal mattress for side sleepers should:

• Relieve pressure on shoulders and hips
• Maintain proper spinal alignment
• Offer medium to medium-soft firmness to contour without sinking
• Support natural curves for pain-free mornings

If your current mattress causes numb arms, sore shoulders, or low-back discomfort, it may be time for an upgrade.

Top 3 Mattresses for Side Sleepers in 2025

After reviewing lab tests, sleep studies, and consumer reports, these three models stand out as the top choices for side sleepers.

1. Helix Midnight / Midnight Luxe — Best Overall for Side Sleepers

Ideal for: Average-weight to heavier side sleepers who want pressure relief and spinal support.

The Helix Midnight series is engineered specifically for side sleepers, offering deep contouring around shoulders and hips without letting your spine collapse. The Midnight Luxe upgrades cooling, support zoning, and pressure relief even further.

Pros

• Excellent pressure relief for side-sleeping curves
• Hybrid design prevents sinking while maintaining plush comfort
• Luxe version includes zoned lumbar support and enhanced cooling

Cons

• Might feel slightly firmer for lightweight sleepers

2. Purple Hybrid / Purple Hybrid Premier — Best for Pressure Relief & Hot Sleepers

Ideal for: Hot sleepers, people with shoulder pain, heavier sleepers, and anyone who dislikes the “sink” of memory foam.

The Purple Hybrid Premier uses Purple’s unique GelFlex Grid — a highly responsive, breathable material that compresses under your shoulders and hips while staying firm under your midsection. It’s one of the coolest-sleeping surfaces on the market.

Pros

• Exceptional cooling and airflow
• Targeted pressure relief supports heavier side sleepers
• Highly durable and responsive — no stuck feeling

Cons

• Unconventional feel may not suit those who prefer classic memory foam

3. Saatva Classic (Plush Soft) — Best Luxury Mattress for Side Sleepers

Ideal for: Side sleepers who want a traditional luxury innerspring feel with a soft, pressure-relieving comfort layer.

The Saatva Classic comes in multiple firmness options, but Plush Soft is designed for side sleepers. The Euro pillow-top adds cushioning while the coil-on-coil structure keeps the spine aligned. It’s also one of the most durable models in the premium category.

Pros

• Plush Soft option provides excellent contouring
• Strong edge support and high-end construction
• Great for combination sleepers as well

Cons

• Some sleepers find the pillow-top warmer than breathable hybrids

Side-by-Side Comparison (Quick Guide)

How to Choose the Best Mattress for Your Body

1. Weight

• Light (<130 lb): Softer mattresses prevent pressure buildup.
• Average (130–230 lb): Medium firmness works best.
• Heavier (>230 lb): Look for hybrid support — Purple Premier excels here.

2. Firmness

Side sleepers typically thrive on soft to medium. Too firm = pressure. Too soft = misalignment.

3. Cooling Needs

If you sleep hot, prioritize breathable foams, coils, or temperature-neutral grids like Purple’s.

4. Sleep Trials & Warranty

Always choose a mattress with at least a 100-night trial. Side sleepers often need time to test pressure relief.

Final Recommendation

If you want a universally strong pick, Helix Midnight (or Midnight Luxe for extra cooling and support) is the best place to start. Hot sleepers or heavier side sleepers should consider the Purple Hybrid Premier, while those seeking a hotel-style luxury feel will love the Saatva Classic Plush Soft.
