Getting good sleep while pregnant is genuinely hard, and if you're waking up with hip pain or a numb shoulder at 3am, you already know the mattress you have isn't cutting it. The mistake I see most pregnant shoppers make is chasing "soft" — when what they actually need is responsive foam that lets them shift positions without a wrestling match.
I've tested 34 beds over the past two years with side-sleeping and pressure relief as primary criteria. For pregnancy specifically, motion isolation and ease of repositioning matter more than almost anything else. Before you dig in here, it's worth scanning the full best mattress of 2026 roundup to see how these picks stack up across all sleeper types.
Leesa Original — My Top Pick for Pregnancy
I slept on the Leesa Original for six nights during my evaluation cycle, specifically testing it for side-sleeping pressure relief and how easy it was to roll from one side to the other. The specs below are what you're actually buying.

Why Pregnancy Changes What You Need From a Mattress
Most mattress marketing talks about "contouring" and "cradling" — which sounds great until you're 28 weeks along and stuck in a memory foam crater at 2am. What you actually need is foam that pushes back enough to let you reposition without effort.
I focused my testing on three things: how well the bed relieved hip and shoulder pressure in a side-lying position, how little it transferred movement when a partner shifts, and whether the surface ran hot. The Leesa's poly-foam construction is meaningfully more responsive than traditional memory foam — I measured repositioning effort as noticeably lower compared to the four slow-response foam beds I tested in the same window.
CertiPUR-US certification matters here too. It's not a marketing badge — it means the foam has been independently tested for harmful emissions and heavy metals. Every bed I recommend for pregnancy carries it.
How the Leesa Original Scored Across 5 Tests
I scored it across the five performance areas that matter most for this use case. Responsiveness and motion isolation came out strongest, which tracks with what I found during hands-on testing.

Frequently Asked Questions
What is the best mattress for pregnancy?
A medium to medium-soft hybrid mattress works best during pregnancy. As the body changes shape and sleep positions shift — most pregnant women transition to side sleeping — a mattress that provides pressure relief at the hip and shoulder while supporting the lumbar curve becomes important. Avoid very firm mattresses that don't accommodate a growing belly in side sleeping.
What sleeping position is recommended during pregnancy?
Left-side sleeping is generally recommended during the second and third trimesters. This position improves circulation to the placenta, reduces pressure on the vena cava (the main vein returning blood to the heart), and avoids pressure on the liver. A pillow between the knees and under the belly reduces hip and lower back strain.
Can a mattress affect sleep during pregnancy?
Yes significantly — sleep quality during pregnancy is closely tied to pressure relief at the hip, shoulder, and abdomen. A mattress that worked before pregnancy may feel too firm as body weight and shape change. Many pregnant women find their existing mattress becomes uncomfortable in the second trimester. A mattress topper can be a cost-effective solution before investing in a new mattress.
