How to Choose a Mattress for Pregnancy

Choosing a mattress for pregnancy gets easier once you stop chasing “best mattress” in general and focus on “best match for how you sleep right now.” Most people end up side-sleeping more, so your mattress needs to do three things well: feel comfortable as your hips and shoulders sink in, keep your spine supported, and not trap heat. If you get those right, you’ll usually avoid that “why does this feel worse at night?” feeling.

Below is a simple decision checklist based on the mattress guidance that comes up again and again for pregnancy: mid-range firmness (about 5.5–6.5), pressure relief, consistent back support, and cooling—plus the right mattress type for your body and preferences.

Pick the right firmness level for side-sleeping

Start with firmness. A common recommendation is to aim for a mattress that lands around 5.5–6.5 on the firmness scale (mid-range). That range tends to work well for side-sleeping because it’s usually balanced enough to:

• Contour so your hips don’t feel like they’re getting stuck or pushed up
• Support enough to help keep your back from feeling overly arched or collapsed

Use this quick guide

• Too soft can let your hips sink more than your spine likes, which can leave you waking up sore.
• Too firm can press harder on your shoulders and hips, especially as you grow and your weight shifts.

Choose this if…

• You sleep on your side most nights and want a solid starting point: mid-range firmness (5.5–6.5).

Prioritize pressure relief around hips and shoulders

Pregnancy changes where you carry weight. In side-sleeping, the biggest pressure points are usually your hips and shoulders. The mattress should feel like it holds you gently, not just flattens under you.

Look for features described as:

• Contouring (the mattress shapes to your body)
• Pressure relief (less pinching or digging at joints)
• Comfort layers that feel supportive, not mushy

You’ll often see this with memory foam (especially medium-firm styles) and in hybrid designs that pair comfort layers with stronger support underneath.

Choose this if…

• You wake up with sore hips, stiff shoulders, or that numb or tingly feeling on one side—choose gentle contouring and real pressure relief, not just “soft.”

Look for consistent support for your back

Comfort isn’t only about softness. For many pregnant sleepers, the goal is to keep your spine feeling mostly in line as your body changes day by day.

That’s why you’ll keep seeing advice about consistent support and back support. In plain terms, you want a mattress that:

• Supports you evenly as you shift positions
• Doesn’t leave your lower back hanging or sinking too much
• Feels stable as your belly and hips grow

A practical way to think about it

If your mattress helps with pressure relief, it should let you sink enough to feel comfortable, without letting your body form a big curve.

Choose this if…

• You want your back to feel supported on side-sleeping nights: focus on consistent support and back support, not only softness.

---

Choose temperature regulation/cooling you can feel at night

Heat build-up can make sleep harder during pregnancy. That’s why cooling shows up so often in mattress advice.

When people talk about temperature regulation or cooling, they usually mean the mattress helps you stay comfortable instead of feeling hot and trapped. The guidance points to mattresses with cooling features or designs that help with airflow and heat control.

What to look for (without overthinking it)

When you’re comparing options, prioritize mattresses described as:

• Cooling or temperature regulation-friendly
• Able to keep you from getting too warm as the night goes on

Choose this if…

• You’re noticing you sleep warmer than you used to: pick the mattress that most clearly supports cooling or temperature control, while still meeting the firmness and pressure relief needs.

Select the best mattress type for your body and preferences (innerspring, all-foam, latex, hybrid)

Different mattress types can feel very different, even when the firmness sounds similar. And the “best mattress type” depends on you—your body and what you want to feel in bed.

Here’s a simple breakdown of the mattress types that come up most often:

Innerspring

• Often feels more responsive and bouncy.
• If you don’t want a bed that “hugs” too much, innerspring may fit better.
• Pair it with comfort layers that still provide pressure relief for hips and shoulders.

All-foam

• Often focuses on contouring and pressure relief.
• If you choose foam, aim for medium-firm support so you don’t sink too far when you sleep on your side.

Latex

• Often feels more springy than many all-foam beds.
• Can work well if you want some give without feeling stuck in the mattress.

Hybrid

• Combines a supportive core (often innerspring) with comfort materials on top (often foam or latex).
• Hybrids show up a lot in pregnancy mattress guidance because they can balance contouring and support.

Choose this if…

• You want a middle path between cushioning and support: start by looking at hybrid options.
• You want strong contouring for pressure relief: consider medium-firm memory foam styles (often in all-foam or as part of a hybrid).

How to decide between plush vs medium-firm without overspending

This is where many people get stuck. Plush can sound like the most comfortable option, but for side-sleeping during pregnancy, too much softness can sometimes cause the aches you’re trying to avoid.

A good approach is to make the decision in two passes:

1. Pick the firmness range first (aim for mid-range around 5.5–6.5).
2. Then choose your feel (plush comfort vs medium-firm support) within that range.

A money-saving mindset that usually helps

• Don’t buy based on “softest option” or “most expensive option.”
• Focus on the features that match side-sleeping needs: pressure relief, consistent support, and cooling.
• If a mattress hits those boxes, it’s often a better use of money than paying extra for features you won’t notice much once you’re lying down.

Choose this if…

• You want comfort and back support: choose plush that still feels medium-firm, or simply go medium-firm with strong pressure relief.

What to consider for back pain during pregnancy

Back pain during pregnancy can come from different places, so this mattress advice stays focused on comfort rather than medical treatment. Still, the mattress features people look for are fairly consistent:

• The best mattress for back pain and pregnancy usually balances support and pressure relief.
• If the mattress is too soft, it can let your hips sink and put extra strain on your back.
• If it’s too firm, it can create more pressure at your shoulders and hips, making it harder to get comfortable enough to sleep.

Choose this if…

• You notice your back feels worse after sleeping: prioritize consistent support for your back and pressure relief so you’re not fighting your position all night.

How to test a pregnancy mattress at home (position changes and comfort checks)

Even after research, pregnancy sleep can be very personal. Test at home in a way that reflects real life: side-sleeping, position changes, and quick comfort checks.

Try this in your testing window

1. Start in your side-sleep position. Give yourself a couple minutes to settle.
2. Pay attention to hips and shoulders. Do they feel gently cushioned, or does anything press hard?
3. Check how your back feels. As you settle, does your lower back feel supported, or do you feel hanging or bowing?
4. Make small position changes. Roll slightly, adjust pillow height, and move your top leg a bit. A good pregnancy mattress should stay supportive when you change positions.
5. Assess heat. If you tend to sleep warm, see whether the bed feels stuffy or uncomfortable after you’ve been still for a while.

Choose this if…

• You want your best mattress for pregnancy decision based on real comfort: test using side-sleeping, pressure point checks, and support checks—not just first-impression softness.

FAQ: What type of mattress is best for pregnancy?

What type of mattress is best for pregnancy?

There isn’t one single “best” type for everyone. The guidance usually points to innerspring, all-foam, latex, or hybrid, and the best pick depends on your body type and preferences. What matters most is that it still delivers gentle contouring or pressure relief, consistent support, and cooling or temperature comfort for side-sleeping.

Is a softer mattress better during pregnancy?

Not automatically. Many people are advised to aim for mid-range firmness (about 5.5–6.5) because it often works better for side-sleeping—supporting your back without putting too much pressure on hips and shoulders.

Soft or firm mattress for pregnancy—what should I choose?

If you’re deciding between soft and firm, use side-sleeping as your guide:

• Go mid-range for a balance of contouring and support.
• Choose firmer only if a softer bed makes you feel like you sink too far.
• Choose softer or plusher only if firmness is creating pressure at shoulders and hips.

How to choose a mattress for pregnancy first trimester?

Start with the same core checklist: side-sleep comfort, pressure relief, support, and temperature regulation or cooling. In the first trimester, you might be able to stay on your preferred side more easily, but the mattress should still feel comfortable and supportive once you settle in.
