[New Launch] Firmflex Posture Support Cushion - Make Your Home Seating Time More Comfortable! Rakuten Store Now Open

To address the 'neck heaviness' and 'shoulder strain' felt during reading, knitting, or using smartphones, and to make your time at home lighter and more comfortable, Firmflex has released the 'Level-Up Cushion,' featuring a unique ergonomic design developed in collaboration with neurosurgeons.

*Key Features*

* 'Magic Wings' to support elbows: A unique design along the flanks that naturally opens the chest and maintains an ideal upright posture.

* Experience 'Zero-Gravity Shoulders': Gently holds both elbows to relieve the weight of the arms, dramatically reducing shoulder strain.

* Ideal 'Golden Slope': Simply placing it on your lap raises the position of your hands, naturally lifting your line of sight.

[Joint Development] The importance of 'supporting in the right position' recognized by neurosurgeons.

This product focuses on the importance of maintaining a natural posture for modern people. Comment from Dr. Kim Hyung-sun: "When relaxing on the sofa, posture often collapses and becomes hunched. Supporting the arms and upper body in the correct position simultaneously is crucial for reducing physical strain."

*Results from Ergonomic EMG Measurements*

During development, muscle activity (µV) was measured with and without the cushion. For the trapezius (shoulder), activity decreased from 62.72 µV to 6.70 µV (approx. 1/10th). For the scalene (neck), it decreased from 16.12 µV to 4.47 µV (approx. 1/4th).
