Inside the SleevePOD: A Look at the 80% Capacity Gain

The SleevePOD is the workhorse of our storage line. The 80% capacity gain over traditional static shelving is not a marketing claim — it is the result of several engineering choices that compound. Here is how it breaks down.

The base footprint

A standard SleevePOD measures 3 ft wide × 8 ft long × 12 ft tall. That footprint is 24 sq ft per pod. A typical SleevePOD installation places multiple pods on a mobile carriage system that shares one aisle across the entire row.

Mobile carriages

The most important density gain comes from the mobile carriage system. Static shelving requires an aisle between every shelf. Mobile shelving requires only one aisle for the entire row, which moves with the operator. In a row of 10 pods, this saves 9 aisles' worth of floor space — roughly 50% of the total area.

Vertical storage

Sleeves are stored vertically rather than horizontally. Vertical storage prevents warping, allows tighter packing, and lets us use shelf depth more efficiently. A single SleevePOD shelf holds 7 channels of vertically stored sleeves with adjustable holders.

Two-level human-reachable design

Many high-density systems use 3 or 4 shelf levels and require ladders or stools. We chose two levels designed to be reachable from the floor. This is slightly less dense but eliminates ladder time, ladder safety risk, and ladder-related slowness in retrieval. Net throughput is higher.

Modularity

Each pod is independent. You can add pods as inventory grows without rebuilding the system. This protects the original investment and avoids the rip-and-replace cycle that kills traditional shelving deployments.

The result

Average SleevePOD capacity is approximately 80 sleeves per pod, in a footprint where traditional shelving would hold roughly 45. That is the 80% number, and it is consistent across our customer base.
