Usually it is the scuppers. Slather silicone around them inside the cockpit and out side the transom, see if the stops it. If it does you can decide how permanent a fix you want to go for.
crawl in there and look up carefully. Take along a flat blade screwdriver and a flashlight. You can usually see where the water is leaking in by brown water marks on the fiberglass. On my old boat, the stern pulpit leaks, also the modified traveller base. This causes water to drip into the hull, then comes out through those overhead hatch boards you'll see when you are in there looking up. Unscrew the hatch boards and you can get a look inside. There is plywood backing the deck. It will probably be all mushy where the leak is.
Re bed the offending part using Boatlife or some similar caulk. I find that silicon aquarium sealer from Home Depot works wonders.
Deck leaks are common. I'll bet there is a leak into the lazerette as well.
Ella, I don't know what year your boat or what side of the cusions were soaked, but I offer two thoughts to consider fwiw. First, on later model boats, there is a port between the Q'berth and the cockpit. On "Great Escape" the seal surrounding the port was poor and water would come into the Q'berth when it rained hard. It took a while to discover the source, but was easy to confirm simply by placing an aluminum pie plate beneath the port and waiting for a rain. The leak was so slow that when we were on the boat (weight towards stern) the water traveled along the ceiling of the Q'berth and dripped off either onto the shelf at the aft end of the Q'berth or into the port lazertte. Only when we were off the boat did the water drip immediately below the port. The second suggestion to check is condensation (water on bottom side of cusions). This time of year with cold water below and sun warmed decks, condensation in the Q'berth can occur easily. If that is the case, there are many on this forum who can offer better ideas than I, but it should be a simple case of simply getting air beneath the cushions. Good luck.
