It is roughly a metre wide and about 0.7 metres high, its face built from loosely coursed rubble and its surface formed by angular slabs laid without mortar. Unassuming in itself, the structure carries a name that gives it an entirely different weight: Leaba Molaise, the bed of the saint.

The name refers to Molaise, the early Christian monk associated with the founding of the monastic settlement on Inishmurray, which sits within one of the most complete early Irish monastic enclosures to survive anywhere. The bench runs between the altar at one end and the west gable at the other, occupying the interior of Teach Molaise, the small stone oratory dedicated to the saint. The designation as a "saint's bed" places it within a tradition found at several Irish pilgrimage sites, where a stone surface associated with a founding figure was believed to carry spiritual or even curative significance. Pilgrims would lie or rest upon such a surface as part of a devotional act, physically connecting themselves with the sanctity attributed to the saint. Whether or not the bench was ever used in precisely that way, the name alone suggests it held meaning well beyond its plain construction. The survey carried out on Inishmurray between 1997 and 1999, published by Jerry O'Sullivan and Tomás Ó Carragáin in 2008, documented the structure as part of a broader record of the island's remarkable collection of early medieval monuments.
