The support intensity can be fixed via a bottom knob, adapting to the lumbar curves of users with different body types. The backrest also features vertical adjustment,่ๅจ with the lumbar support to adjust the overall support structure's position, combined with breathable mesh fabric to effectively alleviate the stuffiness caused by prolonged sitting.

Purchase Recommendations:
For strong lumbar and back support, prioritize the IGrow Floating Island B Air or JD.COM Z5Pro; for dynamic lumbar tracking and recline functions, the Quanpinwu model is more suitable; for those on a budget and seeking durability, the Deli KF303U offers good value. It is recommended to evaluate based on your own body characteristics (such as height and weight) and usage scenarios (such as fixed office work/mobility needs).
