The friction you feel when you first push something across the room is static friction. If you try to push a table, the first push is the hardest part. It seems like a mental block, but there really is a physics reason for it. The reason is static friction.
Friction, in general, is a force that makes it harder for two objects to slide alongside one another. Static friction is the friction that exists between a stationary object and the surface on which it's resting.A frictional force occurs when you try to push an object alongside a surface.
Once the objects have already started moving, kinetic friction takes over. This is the friction that exists between two objects moving relative to each other. Kinetic friction isn't as strong as static friction, and so it is easier to keep the couch moving once the first push is made.

Friction is the force repelling the relative motion of fluid layers, material elements, and solid surfaces sliding against one another
EXPLANATION:
- 'Static friction' is the tangential force to be resolved, in order to cause one body to slip over another. 'Static friction' is the friction between the 'surfaces of two substances' when 'they are not in motion'. 'Static friction' is friction between 'two or more solid objects' that are 'not moving relative to each other'. Static friction, for example, can prevent an object from sliding down an inclined surface.
- A vehicle on a hill parked. The wheel hubs are statically frictioned by the brakes, with static friction holding the wheel to the ground. A handkerchief hanging in a rack. We expect it to remain that way. When one end is too long, we will return to find the towel in the floor since the difference in weight removed the static friction from the towel to the rope.
- 'Kinetic friction' is a force acting among moving surfaces. An 'object moving over a surface' will feel a force as its travel in the opposite direction. The force magnitude depends on the kinetic friction coefficient between the two components. 'Kinetic friction' is the friction that occurs between two or more bodies in motion. For example a coaster sliding against a table, a person sliding down, a sledge sliding across snow or ice, a washing machine pushed along a floor, rubbing both hands together to create heat, and skis sliding against snow.
