5. Operating Instructions: Twin to King Extension
The SOFTSEA Extendable Daybed can be easily converted from a twin size to a king size to accommodate different needs.
- To Extend to King Size:
- Ensure the bed is clear of any bedding or mattresses that would obstruct the extension.
- Locate the pull-out section of the bed frame, typically positioned underneath the main twin bed frame.
- Gently pull the extendable section outwards from the main frame. The mechanism is designed to slide smoothly.
- Continue pulling until the extendable section is fully extended and locks into place, forming a king-sized sleeping surface.
- Place a king-sized mattress or two twin mattresses side-by-side onto the extended frame.
- To Retract to Twin Size:
- Remove any additional mattresses or bedding from the extended section.
- Unlock the extension mechanism (if applicable, refer to specific assembly guide for details on locking mechanism).
- Gently push the extendable section back underneath the main twin bed frame until it is fully retracted.
- Ensure the section is fully nested to maintain the twin bed configuration.

6. Maintenance
Proper care will ensure the longevity and appearance of your SOFTSEA Extendable Daybed.
- Cleaning: Wipe surfaces with a soft, damp cloth. Avoid harsh chemicals or abrasive cleaners, which can damage the wood finish.
- Hardware Check: Periodically check all bolts, screws, and connections. Tighten any loose hardware to maintain stability and prevent squeaking.
- Wood Care: Protect the wood from direct sunlight and extreme temperature changes to prevent warping or cracking. Use coasters or pads if placing items on the frame.
- Movement: When moving the daybed, lift it rather than dragging it to prevent damage to the frame and floor.
