A sectional sofa is a couch built from separate seating sections that connect together, rather than one fixed frame. That means you can arrange it as a straight sofa, add a chaise on either end, or build it into a corner or U-shape, and change the layout later if your room changes. Koala's modular sofas, including the Tamarama, Torquay and Bangalow, all work this way.

No, sectionals vary by how the sections combine, what's inside the seat, and how many ways they reconfigure. Koala's three ranges alone show the spread: the Tamarama runs 30" regular and 38" extra-wide seats over HyperCloud™ foam, the Bangalow pairs S-spring suspension with soft, loose cushions, and the Torquay uses a multi-layer comfort base with its own extra-wide and extra-deep seat option. The right one depends on how deep, wide or firm you want the seat to feel.

Yes, on the Tamarama and Bangalow. Both are built so you can switch the chaise or corner section from the left side to the right side whenever your room layout changes, without buying a new piece. Torquay's sections reshape the same way as part of its general modular design, so check that product page for the specific layouts it supports before you order.

Very. Across the Tamarama, Torquay and Bangalow, you can choose 2, 3 or 4 sections, build a straight sofa, chaise, corner or U-shape layout, and on the Tamarama and Torquay, pick regular or extra-wide seat modules within that. The FAQs on each product page confirm the range runs from a single-seat armchair up to a 10-seat sofa, so a 4-section sofa is one stop on a much longer spectrum, not the ceiling.

Yes, every Koala modular sofa is designed to expand after the original purchase. The Tamarama, Torquay and Bangalow ranges all let you order additional sections separately and add them to your existing sofa, so a 2-section start can grow into a 4-section layout, or further, without replacing what you already own.

The main benefit is that one sofa can seat a range of household sizes and room shapes without buying new furniture every time your space changes. A modular design lets you start smaller and expand later by ordering additional sections, switch a chaise from one side to the other, and take individual sections apart to move house instead of wrestling one huge frame through a doorway. On a Koala modular sofa, that flexibility comes with tool-free assembly and removable, washable covers, so reconfiguring it doesn't mean re-learning how to build it.

Measure your space against the sectional sofa's overall footprint before you order, since it changes with both the range and the number of sections. A base 2-section Tamarama measures 75" wide by 41" deep, a Torquay 83" by 43", and a Bangalow 94" by 39", and each grows from there as you add sections or switch to an extra-wide module. Check the exact dimensions on the Tamarama, Torquay or Bangalow product page for the specific configuration you're building, since a 4-section U-shape takes up meaningfully more floor space than a 4-section straight sofa.

Covers on the Tamarama, Torquay and Bangalow are all removable and washable, so day-to-day spills come off in the wash rather than needing a professional clean. Wipe up spills as they happen where the fabric is water-resistant, and check the care label on your specific range before washing, since fabric composition varies by colorway.
