⚡ At a Glance
  • Heating Performance: 510W heater that warms the area quickly and maintains steady low heat
  • Best for: Small living rooms or studies where a heated table and coffee surface are useful
  • Not ideal for: Homes seeking whole-room heating or without compatible mains voltage

Square walnut-top table with a built-in 510W electric heater and removable tabletop for all-season use. Four corner fixings hold a futon and solid rubberwood legs deliver stable support.


Fast, reliable warmth – thanks to a 510W AC heater

Heater is MSU-501H rated at AC 100V, 510 watts, 50–60Hz, with a handed temperature control knob and an on/off switch. The heating element begins producing warmth roughly 10 to 15 seconds after switching on.

Creates a warm zone quickly for feet and legs while seated, making cold evenings noticeably more comfortable. Manual knob control lets users fine-tune heat during use.

Two-way use as a table – with a removable tabletop for kotatsu mode

Top detaches from the frame and the unit uses a KD (knock-down) assembly method for straightforward dismantling and reassembly. Tabletop removal allows placement of a futon comforter between the frame and top.

Transforms from a regular coffee table into a heated kotatsu for winter, then returns to standard table use in warmer months. Simple assembly and disassembly suit seasonal storage and flexible room layouts.

Stable, attractive finish – with solid rubberwood legs and walnut veneer

Legs are made from natural solid rubberwood while the horizontal surface is a walnut-brown veneer finished with a satin coating. Four specially designed corners retain a futon comforter when in kotatsu configuration.

Provides a robust, low-profile base that complements living-room décor and keeps a futon securely in place. The satin walnut surface resists everyday wear and looks refined as a coffee table.
