Hi SanDiego1K,
These are lie-flat seats (angled to the floor). If you are familiar with LH or SK or OS C-class product, LO seats are more or less the same (minus PTV's).
A small warning: check seat map and make sure there are 3 rows of seats in C cabin (2-2-2 abreast, seats 3A/3B might be blocked for Flight Deck use). If your seat map shows different configuration do not book this flight.
