Wondering if your current bed setup will work with a Big Fig Mattress? You’re in the right place.Whether you're upgrading your mattress or building your dream bedroom from scratch, we've got the info you need. From frames to foundations to adjustable bases, we’ll walk you through what’s compatible, what’s not, and how to make sure your setup is solid — literally. Let’s get into it.
Big Fig Bed & Mattress Accessory Compatibility
Whether it’s a bed frame, foundation, or mattress protector, one question comes up again and again: can you use your existing setup with a Big Fig Mattress — any Big Fig Mattress —and still be covered under our warranty? Or does a better night’s sleep require starting completely from scratch?
Here’s the short answer: maybe.
Now, the long answer: Big Fig isn't your average mattress company, and none of our mattresses — whether you’ve got your eye on the Firm, the Classic, or the Luxe — are designed like the rest. Each one is built from the inside out to support heavier bodies and bigger-figured couples, and that commitment extends beyond the mattress itself. Our foundation is five times stronger than the average, our adjustable base holds up to 1,250 lbs, and our bed frame (crafted from recycled railroad steel, no less) supports up to 1,100 lbs. All three Big Fig mattresses are designed to work seamlessly with this ultra-durable ecosystem.
That said, we understand some folks are just looking for a mattress upgrade — and maybe your current frame or base is still pulling its weight. We’re all for working with what you’ve got, as long as what you’ve got is actually up to the task.
And listen — we know there are other brands out there. If you're peeking at the competition, we get it. You’re doing your homework. But if you're here, you already know that Big Fig is different. We're all about designing a better, stronger, longer-lasting sleep system.
So, what exactly should you look for to feel confident pairing your current setup with a Big Fig mattress? Let’s break it down.
Can You Use Your Existing Foundation With a Big Fig Mattress?
Great question! Whether you’re considering the Big Fig Firm, the Classic, or the Luxe, all our mattresses are compatible with a properly supportive foundation. So yes, you can use your existing foundation — as long as it meets a few important criteria.
First, take a look at what you’ve got. Is your foundation solid or slatted? Either can work, but here's the key: it needs to be rated to support the combined weight of the mattress and the sleepers. Big Fig mattresses are built to support more, so your foundation has to be up to the task. If you’re not 100% sure it can handle the load, it’s better to play it safe and upgrade.
Also important: your foundation will need a frame to rest on — Big Fig mattresses are not designed to be placed directly on the floor or solely on a foundation without proper support underneath.
Another note: we don’t make a traditional box spring, and our Big Fig Foundation is slatted by design. It’s engineered to work with the Firm, Classic, and Luxe mattresses, offering optimal airflow and rock-solid support.
In short? You're in good shape if your current foundation is sturdy, supportive, and paired with a proper frame. But if it’s looking a little questionable — or wasn’t built with durability in mind — it might be time for an upgrade. Your mattress (and your back) will thank you.
Using a Frame From Amazon With a Big Fig Mattress
While you might be tempted to purchase a frame from Amazon due to the low price point, inexpensive bed frames may be made with cheaper materials or less stringent manufacturing standards, affecting their durability and safety.
Also, fuller-figured folks may not be able to withstand the weight load. Although Amazon has bed frames and foundations listed as “heavy duty” you also have to consider the gaps in the foundation. If the bed slats/bars are too far apart, they won’t support the mattress correctly — this is especially true if you have a memory foam or latex mattress since they can sag between wide gaps.
Typically, keeping slats/bars no more than 2 inches apart is best. With the popularity of these frames, it's okay to use them as long as they place something flat, like plywood or fiberboard, between the frame and the mattress.
Using The Bed Frame I Already Own
Rule one… DO NOT use a bed frame and mattress without pairing it with a foundation or box spring. Your mattress needs more support than that! Once you’ve got that out of the way, a bed frame should also adequately support the weight of the foundation, mattress, and sleeper(s). Yes, bed frames have weight limits.
So, how much weight can a bed frame hold? The Big Fig Bed Frame is the best for a heavy person because it supports up to 2,000 lbs. A ~130 lbs mattress and a max of 1,100 lbs per couple on the Big Fig leaves you a solid 700 lbs or more for the foundation. This isn't some wooden frame either; it's a metal bed frame made from recycled railroad steel!
One more thing — you may be wondering if you can put a bed frame around an adjustable base. While the Big Fig Bed Frame is incredibly strong (made from recycled railroad steel!), it’s not designed to go around an adjustable base. Here’s why: The Big Fig Bed Frame is built to directly support a foundation and mattress, not as a decorative outer frame or surround for an adjustable base. It’s a standalone support system, not a platform or open bed frame into which you’d "drop" an adjustable base.
Are All Big Fig Mattresses Compatible With My Existing Adjustable Base?
If you’re considering leveling up your sleep setup with an adjustable base — great move! The ability to raise your head, your feet, or both at once (hello, zero gravity!) doesn’t just feel luxurious — it can also help with things like acid reflux, sleep apnea, and, yes, even snoring.
Now, let’s talk compatibility — are all mattresses compatible with an adjustable base?
The Big Fig Classic and Big Fig Luxe are your best bets here. Both are designed with flexible foam rails instead of a rigid metal border wire, which means they can bend and move with the curves of an adjustable base without resistance. No need for a separate foundation or bed frame — they’re ready to go as long as your adjustable base can support the total weight (that means the mattress plus sleepers).
The Big Fig Firm , on the other hand, is a little different. It’s designed for maximum structure and support, using a sturdier perimeter to provide that ultra-solid, traditional feel. Because of that, it’s not recommended for use with adjustable bases. The reinforced design doesn’t have the flexibility needed to move comfortably with the adjustable sections, and forcing it could compromise the mattress's comfort and longevity.
Another common question: Do you need a box spring or foundation when using an adjustable base? Nope! Adjustable bases are built to act as both a frame and a foundation. That means you can skip the extra pieces — you only need your mattress and the base.
Of course, we truly believe our Big Fig Adjustable Base is the most substantial and supportive option for plus-size sleepers. But if you’re using your own, just double-check that it’s rated to hold the weight of your chosen Big Fig mattress and everyone sleeping on it.
Still on the fence? Our adjustable base reviews are packed with real experiences to help you decide if this upgrade is worth it. (Spoiler alert: most people say yes.)
Using An Existing Platform Bed With a Big Fig Mattress
We love a unique design choice and endorse making your room your own. So if you’re going the platform bed route, that’s cool with us! But, can you put a regular mattress on a platform bed?
The rule for this one is simple: whether it’s a platform bed, the floor, or any other structure beneath your mattress, it should be a solid, level surface that can (You guessed it!) support the weight of the mattress plus sleepers without any issues.
