"折叠式餐具小几" can be translated as "foldable small tray table for utensils" or more contextually fitting as "foldable small side table for dining utensils".
“折叠式” is translated as “foldable”, indicating that the table can be folded.
“餐具” here refers to dining utensils, so “utensils” or “dining utensils” is appropriate.
“小几” is a small side table or tray table, hence “small tray table” or “small side table”.
The choice between "tray table" and "side table" may depend on the specific design and usage context of the item. If it's more of a tray that can be placed on a surface or held, "tray table" might be more fitting. If it's a standalone small table, "side table" would be more appropriate.
