The conservatory is a room that can be used all year round, as long as you have adequate heating. If you are going to be using it during the colder winter months, it will no longer feel like a sunroom – it will be more like an extension of the rest of your house. It’s important you choose furniture to reflect the multipurpose usage of this space, to make it feel appropriate all year round.
Most people use the conservatory as a space to relax. If you are going to do this, consider putting in a proper sofa and some chairs as well. Stay away from rattan, as this will have a distinctly summery feel. Go for neutral colours, like greys and blacks, that will look elegant and sophisticated. You might also want to think about a leather sofa, as this will be a highly versatile option for the conservatory.
