## Customer Reviews

### ⭐⭐⭐⭐⭐ Fantastic buy!
*by R***M on 17 April 2025*

Arrived the next day. Installation was quick and easy. Quality of the material is great. Lumbar and neck support works well on me. Seating cushion is fantastic and comfy. Arm rest works well as well. I only wish I can lock it halfway through when leaning cause it seems it only locks if all the way through. It seems comfy sitting on it after installing but I’ll see after few weeks if I dont get lower back ache anymore.

### ⭐⭐⭐⭐⭐ Comfort on a budget
*by S***O on 4 May 2025*

Very comfortable, well made and clear instructions. Isn't remarkably tall, but the headrest adjusts enough to fit a reasonably large range of people. The lumbar support is generous and comfortable, I have a chronic pain condition and leaning back in the chair or rocking in it are both very nice. Would highly recommend to anyone seeking comfort on a budget

### ⭐⭐⭐⭐ A sturdy chair that's quite comfortable
*by D***R on 7 February 2025*

It's a solid chair, relatively easy to build (took me 40 minutes on my own) with clear instructions. One screw hole in the lumbar section is misaligned, so I was only able to fit one screw but that doesn't seem to be an issue as you lean back into it anyway and that holds it in place. The seat base is firm, but in a supportive, comfortable way. Good height adjustment. Haven't tried the reclining but even in it's most upright position, it's comfortable to sit in with the mesh having enough give that it doesn't dig in.Time will tell how the comfort lasts, but I'm quite happy at the moment and it's a definite improvement over my last chair, especially at the price point.
