All times on this page come from real buyers who logged their actual build time after finishing — not IKEA estimates.
Like most IKEA furniture, the real time is longer than what the instruction booklet implies. The 1h 40m average here comes from buyers who logged their actual build — not the manufacturer's estimate.
Two people are essential — not because the steps are complex, but because the sections are too heavy to position safely alone.
First-timer estimate: 2h 5m–2h 25m — budget this before you start

SÖDERHAMN Sofa section, Kelinge rust — Assembly Overview
Sofa assembly is a category all its own — heavy components, awkward dimensions, and mechanisms that need to function reliably for years. The SÖDERHAMN Sofa section, Kelinge rust averages 1 hour and 40 minutes based on 2 real builds, with a moderate difficulty rating. Two people are essentially required for any large sofa build — the sections are too heavy to maneuver safely solo. Clear plenty of floor space and protect it before you start.
Why this build takes as long as it does
Sofa assembly is physically demanding more than technically complex — the sections are heavy and unwieldy. The mechanism arms (if this is a sofa bed or recliner) are the most critical step and need to be tested before the armrests go on, because they can't be adjusted easily afterward. Two people are essentially required for any large sofa build.
⏱ Time Breakdown
Estimated split based on how real builds typically run
What usually slows people down
- !The weight — sofa sections are much heavier than they look and hard to maneuver without damaging the floor
- !Connecting modular sections tightly enough — visible gaps appear if the connecting hardware isn't fully tightened
- !Mechanism installation on sofa beds — the pull-out arm has to be tested before armrests go on
- !Assembling in the wrong room and then trying to move it through doorways
🛠 How to Assemble It Faster
- 1Assemble in the room it will live in. Moving a large sofa through doorways after assembly is the most common avoidable mistake.
- 2Put moving blankets under sections before flipping — sofa leg feet scratch wood and tile permanently.
- 3Test any pull-out or recliner mechanism fully before attaching armrests. The mechanism is inaccessible after armrests go on.
- 4Tighten section connectors firmly before sitting on the sofa — loose connectors cause visible gaps that widen with use.
Step-by-Step Assembly Guide
- 1Clear a large area — sofa sections need room to maneuver. Protect floors with moving blankets.
- 2Assemble any modular sections separately before joining them.
- 3Attach legs or feet to each section while they're upside down on a padded surface.
- 4Flip sections right-side up and position them. Join sections with the connecting hardware.
- 5Install any mechanism arms for sofa beds or recliners. Test the mechanism before finalizing.
- 6Attach armrests. These are usually the last structural step and define the final shape.
- 7Add cushions and test the full sofa. Check that any pull-out mechanism operates smoothly.

Can I assemble the SÖDERHAMN Sofa section, Kelinge rust alone?
Yes — the SÖDERHAMN Sofa section, Kelinge rust is rated moderate and most buyers complete it solo. Having a second person speeds things up, but it's not required for this build.
What tools do I need to assemble the SÖDERHAMN Sofa section, Kelinge rust?
IKEA includes an allen key with the SÖDERHAMN Sofa section, Kelinge rust, but an electric screwdriver is the single biggest time-saver. A rubber mallet helps seat dowels without marking the wood, and a bubble level catches alignment issues early.
Is the SÖDERHAMN Sofa section, Kelinge rust worth assembling yourself?
At IKEA's price point, self-assembly is usually the practical choice. The SÖDERHAMN Sofa section, Kelinge rust is rated moderate — manageable for most people with a bit of patience.
Can I move the SÖDERHAMN Sofa section, Kelinge rust after assembly?
Yes, but large sofas are very heavy once assembled and difficult to maneuver through doorways. Assembling in the room it will live in is almost always easier than assembling elsewhere and moving it. If you must move it, disassemble the sections for transport rather than trying to move it intact.
How do I fix gaps between SÖDERHAMN sections?
Section gaps usually mean the connecting hardware under the seam isn't fully tightened. Check for cam bolts or hook connectors between the sections and tighten them fully. If gaps reappear after a few weeks, the hardware may have loosened from use — periodic re-tightening is normal for modular sofas.
