How to Choose a Bed Frame | Fit, Support, and Materials

Choosing a bed frame comes down to three things: size, support, and material, so measure your mattress and bedroom before you buy.

For the full breakdown, see our best Beds and Bed Frames guide.

A bed frame is more than a place to park a mattress—it sets the bed’s height, carries its weight, and dictates whether you need a box spring. Whether you’re furnishing a first apartment or upgrading a master suite, the right frame depends on a few decisions you can make before you ever open a shopping tab. The good news: the process is straightforward once you know what to weigh.

Measure the Mattress and the Room First

The single biggest mistake bed-frame shoppers make is buying a frame that doesn’t match their mattress. Standard mattress sizes—twin, full, queen, and king—have fixed dimensions, and a queen mattress on a full frame is a different kind of bedtime surprise than you want.

IKEA’s own buying guidance is blunt on this point: measure your mattress and your room before you commit. A frame that fits the mattress beautifully but leaves no path around the bed is as much of a miss as a frame that’s too small. When you measure the room, leave enough floor space for drawers or doors to open fully, and account for the bed’s footprint, not just the mattress size.

Height is the second measurement that matters. The frame’s height sets how easy it is to get in and out of bed, which matters more as you shop for a guest room or for older sleepers. A lower platform frame suits a modern, low-profile look; a taller frame with a headboard can feel more traditional and makes sitting on the edge of the bed easier.

Wood, Metal, or Upholstered: Picking the Material

The material you choose drives the frame’s look, its weight, and its durability, and each option has a clear set of strengths.

• Wood frames are the classic choice—sturdy, warm, and forgiving to match with almost any decor. Look for solid wood construction and proper joinery over staples or glue. The GSA’s specification for contemporary oak beds emphasizes exactly this: a sturdy frame with quality joinery and a clean finish holds up far better than a cheaply assembled alternative.
• Metal frames tend to be lighter, often less expensive, and easy to move between rooms. They’re a practical default for guest rooms and rentals, but lower-cost metal frames can squeak over time—check the joints and consider whether the added weight of a wood frame is worth the stability.
• Upholstered frames bring a soft headboard into the bedroom and come in fabric or leather finishes. They’re comfortable to lean against while reading, but the fabric needs occasional cleaning, and the padding adds bulk to the frame’s footprint.

Support, Box Springs, and Sizing

A bed frame’s real job is supporting the mattress so it stays flat and keeps its shape. Casper’s guidance makes one key point clear: a platform bed doesn’t require a box spring, so if you choose a platform frame with a solid or tightly slatted base, you can skip the box spring entirely and just place the mattress on top.

If your frame isn’t a platform style—or its slats are spaced too far apart—you’ll need a box spring or foundation underneath. The rule of thumb: slats should be close enough together that the mattress doesn’t sag between them, and larger mattresses need more support in the middle.

That brings up the center support question, and it’s not optional for bigger beds. A queen or king mattress is heavy, and a frame without a center support rail or center legs will sag in the middle over time. When you shop, specifically confirm the frame includes center support for larger sizes. Weight capacity matters too—check what the frame is rated to hold, especially for heavier mattress styles like memory foam or hybrid models.

What the Frame Should Include Before You Buy

Before you finalize a frame, run through the warranty and construction details. A frame that comes with a solid warranty is a frame the manufacturer stands behind, and the warranty terms tell you a lot about expected lifespan.

Aim for a frame with:

• Center support included for queen and king sizes
• Joinery that’s screwed, bolted, or mortised—not stapled
• A finish that’s smooth and even, with no rough edges
• A weight capacity clearly above your mattress’s weight
• Compatibility with your mattress type (check whether slats work with memory foam)
