Pregnancy transforms sleep needs dramatically — a belly that grows weekly, shifting sleep positions, increased pressure on hips and lower back, and temperature sensitivity all require mattress consideration. This guide helps pregnant women find the best mattress in 2025 for each trimester.
How Pregnancy Changes Sleep
| Trimester | Main Sleep Challenge | Mattress Need |
|---|---|---|
| 1st (weeks 1–12) | Fatigue, nausea, frequent urination | Comfortable in any position; responsive material |
| 2nd (weeks 13–27) | Growing belly, start of side sleeping only | Hip pressure relief, shoulder cushioning for side sleeping |
| 3rd (weeks 28–40) | Significant weight increase, sciatica risk, hip pain | Maximum side-sleeping pressure relief, lumbar support, temperature control |
Why Side Sleeping Matters in Pregnancy
After 20 weeks, doctors recommend sleeping on the left side to maximize blood flow to the fetus and reduce pressure on the inferior vena cava (main vein returning blood to the heart). This makes a pressure-relieving side-sleeping mattress critically important in later pregnancy.
Budget Pick
Sweetnight Twilight Hybrid — From $329
Medium-firm 6/10, pocket coils, HSA eligible. 100-night trial.
Ideal Mattress Features During Pregnancy
- Hip and shoulder pressure relief: Medium to soft firmness (4–6) for side sleeping
- Temperature regulation: Pregnant women often sleep hot — gel foam, latex, or hybrid coils recommended
- Responsiveness: Easy repositioning during the night (important as mobility decreases in 3rd trimester)
- Safe materials: GREENGUARD Gold or CertiPUR-US+OEKO-TEX — for the health of both mother and developing baby
- Edge support: Helps getting in and out of bed as pregnancy progresses
Best Mattresses for Pregnancy 2025
#1 PlushBeds Botanical Bliss — Best for Pregnancy Overall
The GREENGUARD Gold certification makes PlushBeds the safest choice for pregnant women — certified for use in sensitive environments including nurseries. Natural latex sleeps cooler than foam, and the responsive feel makes repositioning easy. Available in multiple firmness levels including medium for side sleeping.

#2 Amerisleep AS4 — Best Zoned Pregnancy Support
AS4's medium-soft (4/10) HIVE® zoning provides the shoulder and hip relief needed for left-side sleeping, while maintaining lumbar support for the growing lower back load. The 20-year warranty means it serves long after pregnancy.
#3 Puffy Lux — Best Pressure Relief for Pregnancy
Puffy's Cloud Foam layers provide the deepest hip pressure relief in our lineup — particularly important in the 2nd and 3rd trimesters. Climate Comfort manages the temperature sensitivity common in pregnancy.
#4 Sweetnight (Medium or Soft) — Budget Pregnancy Pick
For budget-conscious parents, Sweetnight's medium gel foam provides CertiPUR-US+OEKO-TEX certified pressure relief at ~$399 queen. Not as certified as PlushBeds, but safe and effective for most pregnant sleepers.
Additional Sleep Aids During Pregnancy
- Pregnancy pillow (full body): C-shaped or U-shaped pillows support belly and back — reduces hip drop
- Wedge pillow: Supports the belly from below during side sleeping
- Adjustable base: Head elevation reduces reflux and heartburn common in 3rd trimester
- Mattress topper: Adding 2–3" gel topper to a too-firm mattress can provide pressure relief without replacing the mattress
After Baby Arrives
The mattress you choose during pregnancy needs to serve you postpartum too — for nursing positions, co-sleeping concerns, and recovery from birth. All five of our recommended mattresses remain excellent choices postpartum and through years of normal adult use.
