Will a 13 full mattress hybrid (137x191x25 cm) fit in a container?
Expert analysis
A 13 full mattress hybrid measuring 54 in × 75 in × 10 in does not fit in a container, but it's about 4 ft 9 in too large at the tightest point. The binding dimension is height: that is the axis where the 13 full mattress hybrid runs out of room. The persisted calculation steps support the reported tightest-point margin. One caveat: assuming 0.1" wall thickness (typical cardboard).
- Binding axis
- Height
- Tightest clearance
- 4 ft 9 in over
- Result
- Height does not clear
It exceeds the opening at the tightest point.
- The height axis runs out of room.
- A <1 in handling allowance is already subtracted.
How the container-fit check works
A container is a fully 3D box — length, width, AND height must accept the item simultaneously; corner reachability is a soft second constraint.
- Treat the container as a 3D box and generate the item’s 6 dimension permutations (3 axes × 2 flips).
- For each permutation, apply the constraint: item ≤ container on length, width, and height simultaneously.
- Check reachability — items longer than arm’s reach can’t be loaded all the way into the back corners.
- Subtract 1.5 in handling clearance on each axis for the mover’s grip plus pivot room.
- Verdict ladder (verdict-tiers.js, shared with door): FITS ≥ 2 in; FITS_TIGHT 0.5–2 in; FITS_VERY_TIGHT 0–0.5 in; DOESN'T_FIT below.
Interior dimensions use the published spec; door rails, ribs, and floor lashings can shave 1–2 in off the usable corners.

Space geometry
- Container floor is flat and rectangular
- No internal partitions or dunnage
Handling
- ±¼ in tape-measure tolerance applied
- 1.5 in handling clearance subtracted from raw margins before the verdict
- Item treated as rigid — cannot compress, bend, or disassemble.
