A king size bed with hydraulic storage gives you the biggest box of any bed, often enough to replace a loft. The catch is weight: a 72 inch wide lid with a thick mattress is heavy, so the board, the pistons and the way the lid is split all matter more than on a smaller bed.
When you shop for a hydraulic bed king size frame, start with the mattress. Here are 9 designs built for a 72 inch wide one, in teak, sheesham, fabric and metal, with notes on lid splits and what to ask the maker. For how the lift works in general, see the hydraulic bed guide. For plain king frames without a box, visit king size bed designs.
Solid Wood King Size Bed with Hydraulic Storage
Teak and sheesham frames look rich in a master bedroom. The frame can be solid, but keep the moving top in ply so the gas lift is not overloaded.

- SizeKing 72 x 78 in
- BuildTeak, golden melamine
- StorageFull hydraulic lift
Raised panels on the headboard echo old teak doors. The whole lid rises at the foot, giving full access to the box.
Tell your carpenterOrder a 19 mm ply lid with a teak lipping on the edge so it matches without the weight.

- SizeKing 72 x 75 in
- BuildSheesham, dark walnut PU
- StorageFull hydraulic lift
The jali (cut lattice) headboard lets light through and keeps the dark sheesham from feeling heavy. Suits a room with a large window.
Tell your carpenterCheck the jali is cut from one solid board, not glued strips, and sanded smooth inside each hole.

- SizeKing 72 x 78 in
- BuildAcacia, clear matte
- StorageFull hydraulic lift
A low, simple frame in light solid wood fits a calm modern room. The low height makes lifting the lid easier for older parents.
Tell your carpenterKeep the mattress top around 20 inches from the floor so sitting and lifting stay comfortable.
Upholstered and Metal King Size Hydraulic Bed Design
Padded frames and steel bases suit flats where termites or damp are a worry. Upholstered beds also soften a large room.

- SizeKing 72 x 78 in
- BuildPly, ivory fabric
- StorageFull hydraulic lift
A tall channel tufted headboard turns the bed wall into the focus of the room. Ivory fabric needs a washable cover in homes with dust.
Tell your carpenterAsk for a stain guard fabric and high density foam at least 2 inches thick in the headboard.

- SizeKing 72 x 75 in
- BuildMS, black powder, SS trim
- StorageFull hydraulic lift
A powder coated steel base with golden stainless steel patti strips gives a sharp, modern look and no termite risk.
Tell your carpenterAsk for SS golden patti, not painted gold, which fades; check welds are ground smooth.

- SizeKing 72 x 78 in
- BuildPly, rust velvet
- StorageFull hydraulic lift
Scalloped tops are a playful change from straight lines. Rust velvet warms up a room with white walls and grey floors.
Tell your carpenterMark the scallop on paper at full size first, so both sides come out equal.
King Size Hydraulic Storage Bed with Split Lids
On a king size bed, hydraulic storage under one big lid can be hard to handle. Splitting it into two lighter lids, each with its own pair of pistons, makes daily use easier.

- SizeKing 72 x 78 in
- BuildPly, grey oak laminate
- StorageTwo lids, side by side
Each half lifts on its own, so one person can reach their side without waking the other. Best for a couple who sleep at different hours.
Tell your carpenterEach lid needs its own pair of pistons matched to half the board and mattress weight.

- SizeKing 72 x 75 in
- BuildPly, walnut laminate
- StorageFoot lift + head drawer
Here the foot section lifts while the head section stays fixed with a drawer below. You keep pillows in place while reaching blankets.
Tell your carpenterPut the split line about 30 inches from the headboard so the foot lid stays light.

- Size6 x 6 ft
- BuildPly, white and grey
- StorageFull hydraulic lift
A 6x6 bed is the carpenter's square king, made for a 72 x 72 inch mattress. It fits rooms that are a little short.
Tell your carpenterConfirm the mattress is 72 x 72 before cutting; a 75 inch mattress will overhang.
Room Size for a King Size Hydraulic Bed
A 72 inch mattress usually ends up in a frame about 76 to 78 inches wide and 82 to 86 inches long once a headboard is added. Add 2 ft of free floor on both sides and you need a room about 11 ft wide. The foot end also needs space, because the lid swings up and you stand there to load the box.
| Room | King fits? | Tip |
|---|---|---|
| 10 x 11 ft | Tight | Choose a 6 x 6 or move to queen |
| 11 x 12 ft | Yes | Slim headboard, wall-hung side shelves |
| 12 x 14 ft | Comfortable | Room for side tables and a wardrobe 3 ft away |
Pistons for a Heavy King Lid
The king lid is the heaviest of all sizes. Shop labels read 150, 200 or 300 kg. Find out if that number covers a single strut or the two together, then size it for board plus mattress. A lid too light for the rating springs open. Too heavy and it will not stay up. Splitting the top into two lids lets each pair work on a lighter load. More on matching ratings is on the hydraulic bed fitting page.
What Makes a King Hydraulic Bed Cost More
- Solid teak or sheesham frame instead of ply.
- Two split lids, which need two pairs of pistons and extra rails.
- Tall upholstered headboards with dense foam.
- Carving, jali work or SS golden trims.
- Extra drawers or a head box on top of the hydraulic box.
Questions people ask
What size is a king size hydraulic bed?
It is built for a 72 inch wide mattress, usually 75 or 78 inches long. The 6x6 version uses a 72 x 72 mattress.
Is a king size bed with hydraulic storage hard to open?
Not if the pistons match the lid. A king size bed hydraulic storage box with matched struts opens with one hand. For daily opening, a split top with two lighter lids is easier than one large lid.
Teak wood or sheesham wood king size bed with hydraulic storage?
Both work. Teak, or sagwan, carries natural oils that keep termites off. Sheesham is hard and heavy with dark streaks and takes polish nicely. Read more on our sheesham bed page.
Are metal king hydraulic beds strong enough?
Yes, a powder coated MS frame with a ply top is strong and termite free. Check the welds and the coating inside the box.
Can I put a king hydraulic bed in a 10 x 10 room?
It will be very tight with no space to walk or open the lid. A queen is a better choice there; see queen size hydraulic beds.
