Firmflex Co., Ltd. has announced the successful funding of its Level-Up Cushion project on Japanese crowdfunding platform Makuake. This ergonomic cushion is designed to maintain proper posture not only during gaming but also while reading or using smartphones, reducing strain on the neck and back.
Popular Korean Gaming Cushion Launches in Japan!

Firmflex launched its Makuake crowdfunding campaign on Tuesday, March 11, 2025 to introduce the Level-Up Cushion to Japan, recently achieving its funding goal to begin domestic sales.
Since 2015, the Korean company has developed gaming peripherals based on e-commerce data. The cushion was created by 30-40s employees who wanted to "game more comfortably despite limited stamina!"
Level-Up Cushion Features

Already popular in Korea for maintaining comfortable posture during reading/gaming, the cushion uses premium memory foam - durable yet comfortable with excellent ergonomic support.

The high-density memory foam provides both support and flexibility, adapting to various positions. It functions as:
• Posture corrector when seated
• Footrest when prone/supine
• Back stretcher
Ideal for those with neck/shoulder pain or poor posture. Learn more at the Makuake project page!
