Sunny Health & Fitness SF-BH6629 45 Degree Hyperextension Roman Chair

TLDR Review: Sunny SF-BH6629 Roman Chair

Published: January 10th, 2026

Pros

  • Effectively serves its intended purpose for hyperextension exercises, strengthening the back safely at home.
  • Made entirely of metal, providing durability and a stable setup for users around 60kg and approximately 1.7m tall.
  • Assembly instructions are mostly straightforward, with clearly numbered screws and nuts to simplify the process.
  • Includes all necessary hardware, and the latest model likely features improvements like foot plates.
  • Provides a stable and reliable workout experience without needing to visit a gym.
  • Quality is acceptable for the price point, offering good value for home fitness enthusiasts.
  • Design and features meet user expectations for a hyperextension Roman chair.
  • Suitable for users around 1.77m tall without issues.

Cons

  • The actual slope angle is closer to 40 degrees, not the advertised 45 degrees, which may affect workout dynamics.
  • Cushioning is thin and reported to wear out within six months, reducing comfort during use.
  • Construction feels somewhat flimsy and unstable after assembly, raising durability concerns.
  • Assembly tools included are inadequate for properly tightening nuts; users should prepare to use their own wrench set.
  • Size and height compatibility may be an issue, especially for individuals shorter than 5'3".
  • Assembly can take more time than expected due to numerous screws, and instructions can be confusing toward the end.
  • Limited range or coverage may restrict some types of exercises.

Bottom Line

This Sunny Health & Fitness SF-BH6629 Roman Chair is a solid choice for anyone wanting an affordable home setup for hyperextensions and back strengthening, especially if you’re around average height and weight. However, be prepared for less-than-padded cushions and a bit of a fiddly assembly – bringing your own tools is a must. If you’re below 5’3” or want a sturdier build with longer-lasting comfort, you might want to explore other models better tailored for shorter users or more durable construction.
