Overview

A black metal twin over twin bunk bed from SHA Cerlin with a fully enclosed top guardrail, an inclined ladder, and metal slat supports that don't require a box spring. Each layer is rated to hold up to 400 lbs.

The enclosed guardrail is the safety detail worth noting: all four sides of the top bunk are closed off with a 14 inch rail rather than leaving one side open, and the listing flags that the upper mattress must sit at least 5 inches below the top of that rail. About 10.6 inches of clearance underneath adds some storage room for bins or seasonal items in a small bedroom.

  • 400 lb capacity per layer
  • 14 inch enclosed top guardrail
  • 10.6 inch underbed clearance
  • No box spring required

Who it's for

Families or dorm setups needing a space saving twin over twin bed with built in safety rails and no box spring to buy separately. Less suited to rooms with low ceilings, since overall bed height isn't specified in the listing.

Pros and cons

Pros
  • Enclosed guardrail on all 4 sides of the top bunk
  • No box spring needed, metal slats support the mattress
  • 10.6 inches of clearance underneath for storage
  • Inclined ladder with rounded rungs
Cons
  • Overall bed height and ceiling clearance needed aren't specified
  • Assembly needs two people, about 30 minutes

Performance notes

Twenty metal slats spread the load per layer, rated up to 400 lbs, roughly the combined weight the brand compares to four 15 year olds. The externally mounted ladder has an inclined angle with smooth round rungs, meant to make climbing easier than a vertical straight ladder.
