What Is The Best Firm Mattress?

The Big Fig Firm Mattress, hands down. It’s extra firm and actually built to support bigger bodies.

Bonus: it comes in all the popular sizes, from twin to California king.

What Makes A Mattress Firm?

A mattress is firm because of its materials and construction—and Big Fig Firm doesn’t mess around. The Big Fig Firm, uses dense comfort layers that don’t compress easily, paired with a solid, supportive core underneath. The top layers are thinner and made from high-density foam that keeps you lifted, not sunken. Below that,individually wrapped steel coils create a stable, responsive foundation that spreads out your weight and keeps your spine aligned, especially if you sleep on your back or stomach. That combo of durable materials and smart design is exactly what gives Big Fig Firm its extra-firm feel—and why it outlasts whatever came before it.

Are Firm Mattresses Better?

It depends on how you sleep and what your body needs, but if you’re a back or stomach sleeper, or someone who needs real support that won’t sag over time, a firm mattress is a smart move. Firm mattresses help keep your spine aligned, especially if you tend to sleep flat. They also provide the kind of surface that holds you up instead of letting you sink, which is especially important for bigger bodies. Plus, they’re often more durable and stay supportive longer than softer options. Bottom line: if you’re tired of soft spots, sore mornings or mattresses that quit too soon, the Big Fig Firm might be best for you.

Is A Firm Mattress Good For Stomach Sleepers

Absolutely. If you sleep on your stomach, a firm mattress is one of the best ways to keep your spine aligned and your lower back pain-free. Big Fig Firm is designed to stop your hips and stomach from sinking too deep, which is exactly what causes that uncomfortable arch in your back. The firmer surface keeps your body lifted and level, helping you stay in a healthier position all night long. Less sag, more support and way fewer “why does my back hurt?” mornings. If you’re not usually a fan of ultra-firm mattresses, check out the Big Fig Classic. Our sleepers find that the Classic is great for multi-position sleepers, including those that sleep on their stomachs that might need a bit more cushion.

Is A Firm Mattress Good For Back Pain?

Yes, especially when it’s built like the Big Fig Firm. While some sleepers may benefit from a medium-firm feel like the Big Fig Luxe, many people with back pain—particularly back and stomach sleepers—need the uncompromising support of a truly firm mattress. The Big Fig Firm combines ultra-dense foam layers with individually wrapped coils to keep your spine aligned, reduce pressure on your lower back and prevent sagging that can lead to pain over time. It’s extra firm by design—because back pain doesn’t stand a chance when your mattress actually shows up for you.

What Cooling Features Does the Big Fig Firm Mattresses Have?

The Big Fig Firm has a quilted top layer that's infused with THERMOGEL COOLING® technology, which activates with moisture to help regulate body temperature and create a cool-to-the-touch feel right against your skin. So, if night sweats are part of your sleep story, this mattress helps keep things dry, breathable and seriously comfortable.

What Is The Best Firm Mattress That Won’t Sag?

That would be the Big Fig Firm. And we don’t just claim durability through the mattress construction—we prove it. In independent lab tests simulating 20 years of use with a 350-lb rolling weight, Big Fig showed virtually no sagging, with less than 0.2” of surface impression. It’s firm. It’s strong. And it’s built to stay that way.

How Does The Big Fig Firm Mattress Compare To A Foam Mattress?

Foam mattresses tend to fold under pressure (literally). They compress without pushing back, which can leave you sagging, stuck and unsupported. The Big Fig Firm is built to do the opposite, delivering extra-firm, no-sink support that keeps your body lifted and your spine aligned. If you’re tired of sinking into soft spots or waking up sore, Big Fig Firm is your upgrade. Foam can’t compete.

How Does The Big Fig Firm Mattress Feel?

It’s stable, even, provides that extra-firm feel back and stomach sleepers love—and stays that way. Looking for a soft, sink-in-and-disappear mattress? This isn’t it.
