This product comes un assembled so be prepared to do the job. However, it may take you a good 20-30 minutes to do a single piece of chair since this has more parts to assemble compared to the table.
Read the instruction manual before proceeding as this will give you a good heads up as to which piece goes to what part. Instruction only comes with a Japanese text but has drawings of the parts so visually you can follow the assembly instruction.
It took me overall a good hour and a half to assemble since I did it alone.
Outcome, the product is sturdy and lightweight. Quality of the materials are not that high but I think it will last depending on how you will use it.
The table is standard for 4 person with just ample space to place the dishes.
