Rank #7 in Best Ab Machine 2026: 10 Ranked, and the 440 lb Claim Four Sellers Share
MERACH Adjustable Sit Up Bench, 136 kg Max
Price and rating as shown on Amazon when we collected them. Both change.
The MERACH Ab Workout Machine sits at number 7 in this guide, priced at £67.99. It is an adjustable sit-up bench with a steel frame, a padded seat, a foam roller backrest and four length settings, and MERACH lists it as model MR-2415. It weighs 8.6 kg and measures 104 x 33.8 x 72.2 cm unfolded.
The interesting part is the load number it does not claim. Four other listings in this guide advertise 440 lb (200 kg); the MERACH claims 136 kg, which it converts to 300 lb — lower than its rivals and lower than its price bracket might suggest, but at least the bullet point and the spec field say the same thing. Where the MERACH does come apart is the ratings. The listing quotes 4.2 out of 5 from 160 ratings, yet its star histogram adds up to exactly 100: 68 five-star, 9 four-star, 9 three-star, 3 two-star and 11 one-star. Those 100 ratings do average 4.2, but they are not the 160 the listing states.
Everything on this page comes from the Amazon listing and its customer reviews, not from any test we ran ourselves.
How those 160 ratings break down
An average hides its own shape. This is the spread behind the 4.2 stars.

Questions people ask
Does the MERACH hold 200 kg like the other benches in this guide?
No. The MERACH listing claims 136 kg, which it converts to 300 lb. The 200 kg (440 lb) figure belongs to other listings, not this one.
Why does the listing say 160 ratings when the histogram is smaller?
The listing states 4.2 out of 5 from 160 ratings, but the star histogram on the same page counts 68 + 9 + 9 + 3 + 11, which is 100. The two figures on the same listing do not match.
What are the dimensions of the MERACH MR-2415?
The listing gives unfolded dimensions of 104 cm x 33.8 cm x 72.2 cm, with an item weight of 8.6 kg.
How long does assembly take?
The listing says assembly takes only 15 minutes and that an instruction manual is included in the package.
What is included with the MERACH sit-up bench?
The listing states one ab machine is included, and the product carries a 1 year warranty.
How does the MERACH adjust for different users?
The listing says the bench has four flexible length adjustments, which MERACH says adapts it to different heights and body types.
