What kind of extra beds do hotels usually add?

Generally, extra beds are folding beds.

In hotels with more than 4 stars, extra beds are generally folded (20% off), with sponge pads and wheels, and the size is generally1.95 * 0.9m. However, there are many sizes of sponge pads, which are generally 7cm and 18cm, so the comfort is not very strong.

Of course, there will also be small single beds. The cost of extra beds varies from hotel to hotel. You can check online for details. If you have any request for an extra bed in the hotel, please contact the hotel in advance.
