## At a glance

- Six plate posts and four integrated vertical barbell holders are claimed for this configuration.
- The listing says it is designed for Olympic plates, including bumper and cast-iron plates, and Olympic bars.
- A vertical tree layout is intended to use less floor space than spread-out equipment storage.

## Pros

## Cons

## Before you buy

- The listing gives conflicting dimensions: 65D x 60W x 130H centimetres versus 65 x 59.99 x 130 cm; 13 kg. It also describes the rack as having six plate posts, while a separate detail lists two racks. Confirm the selected configuration and dimensions before purchase. The listed weight capacity is a manufacturer claim, not an independently verified rating.

## A good fit for

- Home gym users storing Olympic plates and barbells together.
- Buyers who want a vertical storage layout and have room for a rack listed at about 130 cm high.
- Owners of bumper or cast-iron plates who can confirm their plate fit on the posts.

## Less suited to

- Buyers who need confirmed fit for larger-diameter plates without checking first.
- Anyone who requires verified dimensions or independently tested stability and load capacity.

## Customer feedback

Customer feedback is favourable about assembly, everyday use and storing weight, while reports also mention larger plates slipping and slight movement. Build quality and durability experiences are mixed. For a six-post, four-holder storage rack, the reported fit and movement concerns are practical points to weigh alongside its combined vertical storage layout. Aggregate ratings are mostly five-star, but a smaller low-star share means the overall rating does not settle those specific concerns.
- Positive themes: Feedback describes assembly and use as easy.
- Positive themes: Customers report that the rack does its intended storage job and can hold substantial weight.
- Negative themes: Feedback reports that larger plates may slip off.
- Negative themes: Some customers report slight back-and-forth movement.
