Quick answer
A king mattress is 76 by 80 inches per Amerisleep, with a surface area of 42.2 square feet, for a room of about 12 by 12 feet. The three Kartivo beds below are 82.6 to 87 inches long, 75.5 to 78.5 inches wide and 30.5 to 47.6 inches tall, and take about 45 square feet of floor, which is 31 to 32 percent of a 12 by 12 foot room. Their weights are 94, 87.6 and 166 pounds. The 166 pound bed has two drawers and the 94 pound bed has four, which is the opposite of what you would expect, so ask the seller whether the weight is for the whole bed or one carton.
Storage in the headboard, in drawers or both
Storage headboard. A shelf, a ledge or compartments built into the headboard. It is easy to reach from bed and does not need floor space to open.
Drawers. Closed storage in the base. It needs clear floor beside or at the foot of the bed to pull out.
Both. A bed with a storage headboard and drawers, which is the heaviest and the most expensive to move.
Worked example: size, floor space and wall
This is our own arithmetic.
| Bed | Size (L × W × H) | Width minus 76 | Floor area | Share of a 12 × 12 ft room | Wall above in a 96 in room |
|---|---|---|---|---|---|
| 4 drawers, beige | 84.4 × 78 × 41 in | +2 in | 45.7 sq ft | 31.7 percent | 96 − 41 = 55 in |
| Storage headboard, beige | 87 × 75.5 × 47.6 in | −0.5 in | 45.6 sq ft | 31.7 percent | 96 − 47.6 = 48.4 in |
| 2 drawers, white | 82.6 × 78.5 × 30.5 in | +2.5 in | 45.0 sq ft | 31.3 percent | 96 − 30.5 = 65.5 in |
The storage headboard bed is 0.5 inch narrower than a king mattress, which means the mattress overhangs the frame slightly; the other two are wider by 2 and 2.5 inches. In a 12 foot (144 inch) wide room, the widest bed at 78.5 inches centered leaves (144 minus 78.5) divided by 2, which is 32.75 inches on each side, enough to pass but not to open a drawer fully if a drawer pulls out sideways more than that.
Weight. If two people carry the 166 pound bed in pieces, each carries 83 pounds in total, which is a delivery to plan. The 94 pound bed splits into 47 each. Neither listing says how many cartons it ships in.
What the listings say
All three listings are from the same seller and share template text: they say the listing includes the stated features “as reflected in the source listing”, tell you to check the images and included parts and ask you to measure your room, doorway and floor clearance. That text contains no measurements of the drawers, no weight rating and no assembly time, so the table values are the facts and the rest is a prompt to ask.
Kartivo King Bed Frame with 4 Storage Drawers, Upholstered Platform Bed, Beige (ASIN B0HG9BQ3NW). The table gives 84.4 by 78 by 41 inches, a weight of 94 pounds, four drawers and a material of metal, with an upholstered finish in the title. Best for: a king bed with the most drawers. Watch out: the material row says metal while the template mentions an upholstered finish, and the weight is low for four drawers.
Kartivo King Bed Frame with Storage Headboard, Upholstered Platform Bed, Charging Station, No Box Spring Needed, Beige (ASIN B0HHJ34Q5Y). The table gives 87 by 75.5 by 47.6 inches, a weight of 87.6 pounds and iron. The template text mentions storage, drawer storage, a headboard, charging access and a no-box-spring platform, with wood-based and metal parts. Best for: a storage headboard with charging. Watch out: the template says “drawer storage” while the title says storage headboard; ask what is included.
Kartivo King Bed Frame with 2 Storage Drawers, Upholstered Platform Bed, Charging Station, No Box Spring Needed, White (ASIN B0HH6ZPT1V). The table gives 82.6 by 78.5 by 30.5 inches, a weight of 166 pounds, two drawers and an upholstered material. Best for: a low-headboard king bed with two drawers. Watch out: 166 pounds is heavy; ask whether the weight includes the packaging.
How the three compare
| Listing | Storage | Weight | Material row | Headboard height (overall) |
|---|---|---|---|---|
| B0HG9BQ3NW | 4 drawers | 94 lb | Metal | 41 in |
| B0HHJ34Q5Y | Storage headboard | 87.6 lb | Iron | 47.6 in |
| B0HH6ZPT1V | 2 drawers | 166 lb | Upholstered | 30.5 in |
Questions to send the seller
None of the three listings answers these, so send them before you order:
- What does the weight in the table cover? The four-drawer bed at 94 pounds and the two-drawer bed at 166 pounds cannot both be whole-bed weights.
- What are the drawers’ inside dimensions and pull-out length?
- What is the weight rating, and does it include the mattress? None of the tables states one.
- How is the charging station powered, and is there an electrical safety listing?
- How many cartons, and how many people do you need to assemble it?
Keep the answers. A seller who cannot answer the first two has told you something.
How to choose
Pick the storage that suits your habits. Reaching a headboard shelf from bed is easy; drawers hold more.
Do the room math. The beds take about 31 to 32 percent of a 12 by 12 foot room, and a drawer needs floor.
Think about the wall. A tall headboard leaves less wall; see the table.
Expect to carry. 87.6 to 166 pounds is a delivery decision.
Delivery and assembly
A king bed with drawers or a storage headboard arrives heavy and in pieces, and none of the three listings states the number of cartons or the weight of the heaviest one. With weights of 87.6, 94 and 166 pounds, plan for two people at the door and a clear path to the bedroom, and measure the stairs and the turns before the delivery date. If the bed has a charging station, plan the position of the socket before you place it, so the cord does not run under a drawer’s path.
Assemble the bed in the room where it will stand, with the mattress last. A drawer bed in particular is easier to build with the drawers out, and checking that each drawer glides freely before the mattress goes on saves a second assembly. Check the frame’s square corners by measuring both diagonals before tightening, since a bed built slightly out of square makes drawers bind.
Mistakes to avoid
Taking the template text as features. It does not describe how the bed is built.
Ignoring the odd weight. 94 for four drawers and 166 for two is a prompt to ask.
Forgetting the king width. The 78.5 inch bed takes 2.5 inches more than the mattress.
Skipping the power cord question. Two of the three mention charging.
When a different bed is better

Frequently asked questions
How big is an upholstered king bed with storage?
The three listings are 82.6 to 87 inches long and 75.5 to 78.5 inches wide.
How much floor space does it take?
About 45 square feet, or 31 to 32 percent of a 12 by 12 foot room.
Are the drawers big?
The listings do not give drawer sizes. Ask the seller.
Why do the weights look odd?
The two-drawer bed is listed at 166 pounds and the four-drawer bed at 94. Ask whether the weight is for the whole bed or one carton.
Do they need a box spring?
Two of the three titles say no box spring is needed; the four-drawer title does not mention it.
Is the headboard storage easy to reach?
We cannot judge that from a listing; check the photos and the dimensions.
