A platform bed is a frame with its own built-in mattress support, either closely spaced slats or a solid panel, so the mattress sits directly on it without a box spring. It suits anyone using a foam or hybrid mattress, people who want a cleaner and slimmer bed profile, and rooms where every inch of height or storage counts. The range here covers more than 1,100 frames, and about 72% are currently in stock.
Most listings are classic slatted frames in wood or steel, joined by around 115 upholstered designs, about 50 frames with built-in storage and a smaller group with trundles. Prices are per frame and mostly fall between about $270 and $565, with a median near $385. Simple metal bases start under $90, while large solid wood and designer frames reach roughly $3,400.
How a Slatted Deck Replaces the Box Spring
Traditional frames are open rectangles that need a box spring to hold the mattress. A platform design moves that job into the frame itself. That changes three things you will notice at home:
- Height. Without a box spring, the sleeping surface sits several inches closer to the floor. Many frames put the top of a 10-inch mattress around 20 to 24 inches high, which is comfortable for most adults.
- Feel. A firm, even base lets a foam or hybrid mattress perform the way it was designed. Innerspring mattresses also work, but check the mattress maker's guidance on support.
- Cost. You buy one piece instead of two, and there is no separate foundation to replace later.
Slat spacing is the detail to check before buying. Most foam mattress makers ask for gaps of about 3 inches or less; wider gaps can let foam sag between slats and may affect mattress coverage terms. Queen and larger frames should also have a center rail with at least one or two support legs that reach the floor.
Wood, Metal or Upholstered Frames
The material sets the look, the weight and how quiet the bed stays over time.
- Solid wood platform bed. Pine, rubberwood, acacia and other hardwoods give a warm look that fits farmhouse, mid-century and modern rooms. A wood frame is heavy and stable, and solid wood can be refinished. Engineered wood with a veneer looks similar for less money but is less forgiving of repeated assembly.
- Steel frames. Metal are light for their strength, often the most affordable option and easy to move. Many have tall legs that leave room for under-bed bins. Choose one with plastic or rubber caps at joints to avoid squeaks.
- Upholstered. A padded headboard and fabric-wrapped rails in velvet, linen or performance fabric make the bed feel like furniture rather than hardware. These overlap with our full range of upholstered beds, which also includes panel and wingback designs.
Headboards, Footboards and Low-Profile Designs
Titles in this range often mention a headboard, a footboard or both. A headboard gives you something to lean on when reading and protects the wall; tufted and button-back styles add softness, while slatted wood or simple metal headboards keep things open. A footboard frames the bed visually but adds length, so measure walkways at the foot of the bed in smaller rooms.
A low, modern design often skips both and relies on a low, wide base with the mattress set slightly inset. These look clean and suit rooms with a window behind the bed. If you lean against the wall at night, a frame with headboard brackets lets you add one later.
Platform Bed With Drawers or a Trundle
Built-in storage solves a common small-bedroom problem. Options here include frames with drawers on one or both sides, frames with shelf headboards and built-in charging outlets, and trundle frames that pull out a second sleeping surface for guests. Drawers need clear floor space beside the bed to open fully, usually around 18 to 24 inches. If you want a frame where storage is the main point, browse our dedicated storage beds.
Picking the Right Size
Platform frames come in standard US mattress sizes. Choose the mattress first, then the frame, and add the frame's own overhang to your room plan.
- Twin: 38 x 75 inches, good for kids and guest rooms.
- Full: 54 x 75 inches, for a single adult who wants more width.
- Queen: 60 x 80 inches, the most popular size for couples; see queen bed frames for more options.
- King: 76 x 80 inches, a king suits larger primary bedrooms; more choices sit under king bed frames.
Leave at least 24 inches of walkway on the sides you use and 30 inches or more in front of dressers so drawers can open. Everything here also belongs to our broader bed collection.
Putting It Together and Keeping It Quiet
Most frames ship flat with hardware and take one to two hours for two people. Tighten every bolt once the bed is in place, then again after the first few weeks, because wood settles and metal joints seat themselves under load. A small square of felt between metal parts stops most squeaks. Vacuum under the slats every few months to keep dust from collecting, and rotate the mattress as its maker recommends.
Slatted Frame FAQ
Do you need a box spring with a platform bed?
No. The slats or solid deck replace the box spring. Adding one would raise the bed too high and can put stress on the slats. If you want extra height, choose a frame with taller legs instead.
How far apart should the slats be?
About 3 inches or less is the common guidance for foam and hybrid mattresses. Some frames use wider gaps and add a bunkie board or fabric strip; check the listing before you buy a heavier mattress.
Is a wood or metal frame better?
Wood is heavier, quieter and more furniture-like; metal is lighter, cheaper and easier to move. Both last for years when the joints are kept tight. Choose based on room style and whether you move often.
Can a full size frame hold two adults?
Most full frames support two adults by weight, but at 54 inches wide the mattress gives each person only 27 inches, about the width of a crib mattress. Couples usually find a queen far more comfortable.
What height should the frame be?
Aim for the top of the mattress to sit roughly at knee height when you stand next to it, usually 20 to 25 inches. Low frames suit modern rooms and kids; higher legs give space for storage bins.
