How to Put an Ottoman Bed Together

To put an ottoman bed together, attach the headboard and side rails, fix the footboard, secure the central support bar, assemble the ottoman lift frame, install the hydraulics, and fit the slats or platform base. Always build the frame first, then attach the lifting mechanism.

Struggling to assemble an ottoman bed? You’re not alone. Many people find the hydraulic system confusing or worry about fitting the lift frame incorrectly.
The good news? Putting an ottoman bed together is easy when you follow the right steps, and you don’t need professional help.

What You Need Before Assembly

Tools Required

Most ottoman beds come with fittings, but having these tools makes assembly much easier.

• Phillips screwdriver
• Allen keys (usually included)
• Small wrench or spanner
• Rubber mallet (optional)
• Zip bags for spare screws

Prepare the Space

A clean, open area will make assembly smoother.

• Clear the room around the bed
• Lay out all parts and screws
• Keep instructions nearby

How to Put an Ottoman Bed Together — Step-by-Step

Step 1 — Assemble the Headboard and Side Rails

Start by building the outer frame of the bed.

• Attach the side rails to the headboard
• Tighten corner brackets
• Ensure all joints are aligned straight

Step 2 — Attach the Footboard

This completes the rectangular frame.

• Fix the footboard to the two side rails
• Use the bolts provided
• Double-check alignment before tightening

Step 3 — Install the Centre Support Bar

Ottoman beds need strong internal support.

• Place the centre bar in the middle
• Secure it with screws
• Ensure the bar sits tightly with no movement

Step 4 — Build the Ottoman Lift Frame

This is the frame that will lift to access storage.

• Lay the metal lift frame on the floor
• Attach any hinges or brackets as shown
• Keep all screws slightly loose for adjustments

Step 5 — Fix the Lift Frame to the Bed Base

Once built, attach the mechanism to the main frame.

• Line up hinge brackets
• Tighten the bolts securely
• Test the movement without the mattress

Step 6 — Attach the Hydraulic Gas Pistons

Hydraulics make lifting smooth and effortless.

• Clip or bolt each piston into place
• Make sure both sides are equal strength
• Lift and lower the frame gently to test

Step 7 — Fit the Slats or Platform Base

Different ottoman beds use slats or a solid base.

• Insert slats into plastic holders
• Or place the solid topper on the lift frame
• Ensure everything locks in securely

Step 8 — Add the Mattress and Test the Lift

Final step, test the full mechanism.

• Place mattress in the centre
• Lift the frame slowly
• Make sure it stays open when raised

Common Issues During Assembly (And Fixes)

Lift Frame Feels Too Heavy

This usually happens before the hydraulics are attached.

• Install the pistons correctly
• Check if any bolts are overtightened

Mechanism Doesn’t Move Smoothly

Often caused by misalignment.

• Loosen the hinge screws slightly
• Realign the frame
• Tighten again evenly

Bed Base Is Not Sitting Straight

Side rails may be loose.

• Tighten all corner brackets
• Ensure the centre bar is locked properly

Real-Life Example

“One customer struggled to lift the bed during assembly because the pistons were installed upside down. After flipping them to the correct direction, the bed lifted effortlessly and stayed open without support.”

Helpful Stats & Facts

• Most ottoman beds take 45–60 minutes to assemble.
• Gas pistons are designed to lift 40–80 kg depending on size.
