C CUSHION LAB 超高密度腰部クッション - 特許取得済みの人間工学に基づいたマルチリージョンの固定バックサポートで腰痛の緩和 - オフィスチェア、車、ソファ、飛行機用のストラップ付き腰部サポートクッション - グレー

I bought a Secretlabs chair and also bought this, and their seat cushion - it's changed my world. I have 3 other back cushions - and this is by far the best. If you have back trouble - I recommend this. Bought with their seat cushion - it has changed my life.

Excellent. Although the product is extremely expensive, it is thoroughly worth it & I cannot recommend it highly enough. It’s been a game changer for me, giving me much relief whilst sitting which I have been unable to do because of grave spinal issues. Extremely satisfied

Before I got this one, I tried few other popular lumbar supports on Amazon, nothing worked for me. Other lumbar pillows were all uncomfortable for it was too soft to support my back. This one is amazing, but if you are looking for something that is soft and comfortable, don't get this one. This is very firm and supportive. It feels like it also corrects my posture. I will give it a 5 star!

It provides support to my back but the material may not be ideal for hot weather.

es un buen cojín ergonómico pero es un poco duro.
