Our bassinets are approximately 75 x 33 x 22cmcentimeters (29.5 x 13 x 8.8 inches) in size and can hold babies weighing up to 11kgkilograms (24.2lbpounds). Whilst our bassinets are designed for babies up to two years old, we won’t be able to provide one if your baby doesn’t fit safely. Please note bassinets are limited in number and subject to availability.
