How to buy for two problems at once
1. Work out which pain is driving the other
This is the diagnostic step almost everyone skips, and it changes the answer. Hip pain frequently causes back pain rather than accompanying it: when one hip hurts, you unconsciously shift weight off it, your pelvis tilts, and your lower back takes up the slack. Fix the hip pressure and the back complaint often quiets down on its own. It can also run the other way — a lumbar problem referring pain down into the hip and buttock, which is closer to what we describe on our sciatica page.
A rough test: if the hip is sore to press on and worst on the side you sleep on, treat it as a pressure problem and prioritize the comfort layer. If the pain is deep, radiating, and worse when you first stand up, treat it as a support problem and prioritize the core.
2. Look at the comfort layer, not just the firmness number
Two mattresses can both be labeled medium and feel completely different over a sore hip, because the number describes the whole bed while your hip only ever meets the top two or three inches. A pillow-top hybrid is the classic answer here: the coils underneath hold the spine level while the quilted layer above gives the hip somewhere to settle. That combination is why the Sweetnight leads this list rather than the firmer beds that top our other pages.
3. Be honest about your weight
A generous comfort layer is only generous if you do not compress straight through it. Past roughly 230 pounds, a soft top layer over a weak core bottoms out and you end up resting on the support foam anyway — worst of both worlds. At that point the coil-supported DreamCloud is the more reliable pick even though its surface is firmer, because the layer you actually sink into is doing its job rather than being crushed flat. Our heavier-bodies page covers this threshold in more detail.
Two cheaper things to try first
Before replacing a mattress, two interventions cost far less and solve a surprising share of hip-plus-back complaints.
The first is a pillow between your knees if you sleep on your side. Without one, the upper leg falls forward and rotates the pelvis, which twists the lower back and grinds the underside hip. It is a genuinely effective, nearly free fix, and it is worth a week of trying before you spend anything.
The second is a topper, if and only if your current mattress is supportive but too hard. A three-inch high-density topper adds exactly the hip cushioning this page is about, without touching the support core you already have. If the bed sags, though, a topper will do nothing — read our mattress-versus-topper guide to tell the two situations apart, then see the topper picks.
Where certifications come in
Every mattress here names CertiPUR-UScertified foam, which covers the foam’s chemical content and emissions but not the fire barrier — so it is silent on fiberglass. Two of these picks go further and state a fiberglass-free build outright. If that matters to you, our fiberglass-free list shows which beds actually say it, and the certification decoder explains what each badge does and does not audit.
