You can request to change the type of bed you have booked by contacting your accommodation. Contact details for your accommodation can be found on your Bookings page, as shown in the example below:

Please note that if you've booked a hotel, you can get in touch with them directly to request a different bed. However, if you've booked an apartment or chalet it is unlikely that you will be able to change the bed type. You can still check with your accommodation directly if they can facilitate your request.
