## Customer Reviews

### ⭐⭐⭐⭐⭐ Solid back extension chair
*by Q***S on September 6, 2024*

This Roman chair is very good quality. The adjustability is very easy and effective and it helps me to work my back muscles precisely. The back stretching feature is very effective and well worth the money.

### ⭐⭐⭐⭐ Nice value, assembly slightly inconvenienced
*by A***U on May 23, 2025*

Missing a few lock nuts and bolts. Otherwise it would have been a 5. Solid build.

### ⭐⭐⭐⭐⭐ Highly recommended
*by J***E on November 23, 2024*

Simple operation can accurately stretch the back muscles, and every time I use it, I feel that my tight back relaxes at once, and my long-term back pain is also relieved. It's super convenient to use wherever you are.
