If you're a side sleeper, choosing the right mattress is already one of the biggest factors in getting a good night's sleep. Add an adjustable bed into the equation, and your mattress choice becomes even more important.

Not every mattress bends properly on an adjustable base. Some lose support over time, while others don't provide enough pressure relief for the shoulders and hips—the two areas side sleepers struggle with the most.

The good news? Modern hybrid and memory foam mattresses are designed to work exceptionally well with adjustable bases, providing customized comfort, better spinal alignment, and less pressure on sensitive joints.

In this guide, we'll cover exactly what side sleepers should look for, which mattress types perform best, and some of our favorite options for 2026.

Why Side Sleepers Need the Right Mattress

Unlike back or stomach sleepers, side sleepers place much more pressure on two areas:

• Shoulders
• Hips

If a mattress is too firm, those pressure points become sore throughout the night.

If it's too soft, your spine can sink out of alignment, leading to lower back pain.

The goal is finding the sweet spot:

• Excellent pressure relief
• Proper spinal support
• Enough flexibility for an adjustable base

Why an Adjustable Bed Helps Side Sleepers

Many people purchase an adjustable base to watch TV or read in bed.

Side sleepers quickly discover another major benefit:

Better Pressure Relief

Slightly elevating the head and knees reduces pressure across the hips and shoulders.

Improved Spinal Alignment

Adjustable beds help maintain a more natural curve of the spine while sleeping.

Easier Movement

People with arthritis or joint pain often find getting in and out of bed much easier.

Reduced Snoring

A slightly elevated head can help reduce snoring and improve breathing throughout the night.

What Makes a Mattress Adjustable Base Compatible?

Not every mattress is designed to flex hundreds or even thousands of times.

Look for mattresses that feature:

• Flexible foam layers
• Individually wrapped coils
• Reinforced edge support
• Adjustable base compatibility from the manufacturer

Avoid:

• Traditional innerspring mattresses with connected coils
• Extra-rigid mattress constructions
• Older-style Bonnell spring mattresses

Common Mistakes to Avoid

Buying a mattress that's too firm

Many people assume firmer is always better for back support.

For side sleepers, this often creates shoulder and hip pain.

---

Choosing an older innerspring mattress

Traditional spring systems don't flex well and can wear prematurely when paired with an adjustable base.

---

Ignoring cooling features

Memory foam can trap heat.

Look for:

• Gel-infused foams
• Cooling covers
• Breathable hybrid designs

Frequently Asked Questions

Can I use any mattress on an adjustable bed?

No. Most modern hybrid, latex, and memory foam mattresses work well, but many traditional innerspring mattresses are not designed to flex repeatedly.

---

Is memory foam or hybrid better for side sleepers?

Both are excellent choices.

Memory foam offers deeper contouring and pressure relief, while hybrids combine cushioning with better airflow, responsiveness, and edge support.

---

What firmness should side sleepers choose?

Most side sleepers find the best balance of comfort and support with a medium to medium-firm mattress.

---

Does an adjustable bed help shoulder pain?

Yes. Elevating the head and legs slightly can reduce pressure on the shoulders and improve overall spinal alignment, especially when paired with a supportive mattress.
