How big is a twin size mattress?

A twin size mattress is the smallest of the adult-size mattresses, typically 38” X 75”. This would be suitable for a child who has outgrown their toddler bed, a single adult, or those with small bedrooms. It’s common to see this size utilized for daybeds, bunk beds, dorm rooms, or in smaller guest bedrooms.

Fact

 Dogs sniff good smells with their left nostril.

Dogs normally start sniffing with their right nostril, then keep it there if the smell could signal danger, but they’ll shift to the left side for something pleasant, like food or a mating partner.
