Quick answer
Amerisleep gives a California king as 72 by 84 inches, 42.0 square feet, for a room of about 12 by 12 feet. The FinerFurnis floor bed with two drawers weighs 95.9 pounds and has no headboard. The Kartivo upholstered storage headboard bed is listed at 90.5 by 80.5 by 31 inches. The Upcanso 16 inch steel frame is 83.6 by 71.6 by 16 inches, 46.2 pounds, with 14 inches of storage in its title and an upper-bound volume of 48.5 cubic feet. Drawers hold less than open space but keep things closed.

Drawers, headboard storage or open space
Drawers. The FinerFurnis has two, and the listing gives no drawer size. A storage headboard. The Kartivo has one, with no size in the text we read. Open space. The Upcanso states 14 inches of clearance.

Worked example: room, volume and weight
This is our own arithmetic.
- Open space. Upcanso: 14 times 71.6 times 83.6 divided by 1,728 is 48.5 cubic feet, an upper bound.
- Floor. The Kartivo bed at 90.5 by 80.5 inches is 7,285 square inches, or 50.6 square feet, 35 percent of a 12 by 12 foot room (144 square feet). The mattress alone is 29 percent.
- Margins. The Kartivo is 8.5 inches wider and 6.5 inches longer than the mattress; the Upcanso is 0.4 inch narrower and 0.4 inch shorter.
- Heights. With a 10 inch mattress the tops are 26 inches on the Upcanso. The FinerFurnis is a floor bed; the listing gives no height in the text we read, and its sibling cal king floor beds are 7.68 inches, which would put the top near 17.68 inches, but we did not read that on this page.
- Weight. The FinerFurnis at 95.9 pounds is 48 pounds each for two carriers; the Upcanso at 46.2 pounds is easier.

How the three compare
| Listing | Storage | Size | Weight | Rating |
|---|---|---|---|---|
| FinerFurnis | 2 drawers, size not stated | Not stated | 95.9 lb | Not stated |
| Kartivo | Storage headboard, size not stated | 90.5 × 80.5 × 31 in | Not stated | Not stated |

Questions to ask
Ask for the FinerFurnis’s drawer sizes and assembled dimensions, the Kartivo’s storage dimensions and weight and the Upcanso’s true rating. Ask also about delivery: a cal king bed with drawers arrives heavy.
How to choose
Choose the kind of storage. Closed drawers, a headboard shelf or open space.
Do the room math. 35 percent of a 12 by 12 room for the Kartivo.
Check the weight. 95.9 pounds is a two-person carry.
Check the rating. Use the lower for the Upcanso.
Delivery of a cal king drawer bed
A cal king bed with drawers is heavy and long. The FinerFurnis weighs 95.9 pounds, which is two people carrying 48 pounds each. The Kartivo listing gives no weight in the text we read, and the Upcanso is 46.2 pounds. A cal king bed’s carton can be 7 feet or more, so measure the stairs, the door and the turn. Ask the seller for the carton count and the weight of the heaviest piece, and assemble in the room where the bed will stand.
Drawers, headboard storage and open space compared
The three kinds of storage hold different things. Drawers keep clothes and linen closed, and the two drawers of the FinerFurnis have no stated size. A storage headboard holds things you reach from bed: books, a phone, glasses. Open space holds bins and luggage, and the Upcanso’s 14 inches of clearance is at most 48.5 cubic feet. For a cal king bed, a combination is possible: a steel frame with open space, plus a bedside bookshelf, as in our bedside bookshelf guide, gives open storage and a reach-from-bed shelf.
Questions to send
Ask for the drawer dimensions and weight limit, the assembled size of the FinerFurnis, the storage size of the Kartivo headboard and whether it is for books or bulky items, and the true rating of the Upcanso. Ask whether the Kartivo’s template text omits features such as a power outlet.
Mistakes to avoid
Expecting drawer sizes. Two of three give none.
Buying a king frame for a cal king mattress. A cal king is 72 by 84.
Ignoring the headboard storage. Ask how big it is.
Skipping the delivery plan. A heavy bed needs help.
When a different bed is better
For a cal king without storage, see california king bed frame. For an upholstered cal king, see california king upholstered bed. For the king version, see king bed frame with drawers underneath.
To decide between the three, make a list of what you want to store and where you want to reach it. If it is clothes, drawers. If it is books and a phone, a headboard shelf. If it is luggage and bins, open space. A person who wants all three would need a combination, such as the Upcanso frame plus a bedside shelf and a small chest.
Also consider the floor. A floor bed with drawers sits flush, so you cannot sweep under it; the drawers are on the sides and take floor space when open. The steel frame lifts the bed and leaves open space you can reach. In a small room, open space under a steel frame is the more flexible choice, because nothing needs room to open. In a large room, drawers keep the look tidy.
For the weight, a cal king mattress is heavy, and the bed under it is a long span. The Upcanso lists nine legs; the other two do not state a leg count or a center support in the text we read, so ask, and see our bed frame middle support guide for what to look for.
Whichever you choose, keep the dimensions of your room next to the table: the mattress, the bed, the walkway and the drawers’ pull-out. A cal king bed is one of the largest pieces of furniture you can buy, and a few minutes with a tape measure and a roll of masking tape on the floor is the cheapest way to avoid a mistake.
