Collection: King Bed Frames | Mattress Miracle™ Brantford

Buying a king size mattress with a frame

A king size mattress with a frame from Mattress Miracle starts at $897 for an everyday bed: the Elysian Velvet Platform ($470) with a C.J. Mulholland Series 4000 king mattress ($427). Our king size mattresses run from $302 to $4,315 across 41 models. The only cheaper pairing uses the $302 Restonit 5-inch foam mattress, which is sold for RVs and bunks.

The order total also decides delivery. Bought alone, the Elysian is a furniture order under $500 and pays $80. Put the mattress in the same order and it clears $500, so white glove delivery is free on most orders. Every other king frame on this page costs $550 or more and clears the line by itself.

Choose the mattress first, then the frame that suits it. The mattress does the work every night, and its warranty card says what support it needs underneath. A middle-of-the-road pair is the Level platform bed, which needs no box spring ($845), with a Sleep In Ortho Care king ($980), for $1,825. Our advisors' frame and mattress pairings by budget list more combinations.

King bed frame size: room, doorways and stairs

A king bed frame is built around a mattress 76 inches wide and 80 inches long. The Better Sleep Council puts that at about 16 inches wider than a queen. A California king is a different shape, 72 by 84 inches, so the two mattresses do not swap between frames. None of the 40 frames here is sold in California king, so call before you order one. Our king mattress dimensions in inches and centimetres has the metric numbers.

The frame always measures more than the mattress. Beaudoin's spec page for the Adam gives its king as 78 by 80 inches. A storage bed grows far beyond that. Our listing for the Lethbridge velvet storage bed with three benches gives the king at 104 inches wide by 99 inches long. The benches run down both sides and across the foot.

For walking room, the Sleep Foundation suggests leaving about 24 inches between the bed and the walls around it. For a plain king mattress, that means a wall at least 124 inches (10 feet 4 inches) wide. The room should be about 104 inches (8 feet 8 inches) deep, counting 24 inches at the foot. The Lethbridge needs a wall of about 12 feet 8 inches. Our king bed frame buying guide goes further on centre support and what to check on a frame before you buy.

The Sleep Foundation also tells buyers to measure the entryway, staircases and doorways. It notes that the extra width of a standard king makes it a tighter fit through doorways. Our split king box spring comes as two 38 by 80 inch halves that go up a stairwell one at a time.

King bed frames by type and price

The 40 king frames at Mattress Miracle fall into six groups, and the prices below are for the king size only. Twenty-nine come from Beaudoin, a Quebec maker that says its beds are entirely conceived and manufactured in Canada. The other 11 are from IFDC.

Under $600 you are buying a padded headboard on a platform. The King Elora, whose headboard reclines for reading, is $550 and comes in king only. One step up, the drawer beds put storage under the mattress. The Allison has two front drawers, the Celestre two per side, and the Saunder two front plus two side drawers. Our king platform beds page shows them side by side.

The Level is the plainest frame here. Beaudoin builds the king Level as two 39 by 80 inch platforms side by side, rates the pair at 1,200 lb and lists a total height of 13 inches. The two halves also carry upstairs easily.

Lift-up storage uses the whole space under the bed. The Ashford hydraulic lift storage bed ($900) raises the mattress on gas pistons, so leave clearance above the bed for it to open. The Windsor ($1,295) and Lethbridge ($1,695) use three lift-up benches instead. More drawer and bench designs are on our king bed frames with storage page.

The 28 Beaudoin upholstered listings cover 14 designs, most sold with a choice of Woodland or Absolute footboard, from the Ennis at $1,740 to the Chelsea at $1,990. Beaudoin's spec page for the Adam lists an 850 lb weight capacity, a 17 inch base height and a one-year warranty on manufacturing defects. Browse them on our king upholstered bed frames page. Keeping the frame you have? Beaudoin's padded king headboards start at $600 for the Ennis.

Does a king mattress need a box spring?

A king mattress needs a box spring only if its maker says so. Foam, latex and most hybrid mattresses sit directly on a platform, so the frames in the first five rows of the table go without one. A traditional innerspring sold with a matching foundation needs a frame built to hold it. Beaudoin makes its upholstered beds with either a platform or a box spring support, so call us to confirm which one a listing comes with. Our standard king box spring is $279.99 in 2, 5 and 7 1/2 inch heights, and the split king version is $310.

Centre support matters on a king. The frame spans 76 inches, so it needs a centre rail with legs down to the floor, or split halves like the Level that each carry their own load. Read the mattress warranty for its slat-spacing rule as well, since each maker sets its own. Skipping centre support is the first of the five mistakes buyers make with king platform frames; slat spacing is the second.

Beaudoin lists the Adam as compatible with adjustable bases. If you want the head or foot to lift, our king adjustable beds start at $799. Split king adjustable bases, where each side moves on its own, start at $2,100.
