Dreambaby Safety gates are some of the most important parts of safety around the home. They are a great way to protect children from entering potentially hazardous areas of the house, or keeping them in a supervised area. Some openings are wider and require extensions to be added to the gates - and now they come in a set! The Chelsea Set comes with one standard (75cm) gate and two 9cm extensions. The gate swings closed automatically - the one handed operation for adults is super convenient! A cost effective and convenient way to add safety and security to your home.
