STORAGE UNITS FOR OVERSIZED BELONGINGS
Mattresses
This obviously depends on which mattress size you’re storing. Smaller mattresses will fit in almost any storage unit, while queen and king-sized mattresses won’t fit in smaller units.
Twin and full-size mattress: A 5×5 will easily accommodate all mattresses smaller than a queen-size mattress.
Queen-size mattress: Though you might be able to squeeze a queen-size mattress into a 5×5, it’s going to be a really tight fit. A 5×10 will be much better.
King-size mattress: There’s no chance you’ll get a king-size mattress into a 5×5, but like the queen-size mattress, the king will fit nicely in a 5×10 or larger.
