Before considering specific features, consider these crucial questions:
●What size is your outdoor space?
●How many people will regularly use the set?
●What's your typical entertainment style?
●What weather conditions will the furniture face?
●Who are the primary users (families with children, elderly, etc.)?

The right size dining set ensures comfortable dining and easy movement. For sizing, use this practical guide: allow 24-30 inches of table width per person and maintain 36-48 inches of clearance around the table for chair movement. For a family of four, a 48-inch table works well, while a 60-inch table comfortably seats six. For larger gatherings, consider 72-84 inch tables.

For the cleaning part, different ways are used for different materials. If you need to remove the stain or dust on surface, you can wipe it with mild detergent and a soft cloth for aluminum or metal products, regular clean with a damp cloth to stay flexible and avoid cracks for the wicker product. If you need to clean the product with seat cushions and back cushions, you can easily remove the coverings and clean it after pulling the zipper down. After that, you can dry it in the well-ventilated area but not expose it to the sun for a long time.
For the maintenance part, it’s necessary to check regularly if it’s damaged or loose for the connected parts. Although it’s weather resistant, you need to cover it with a dust cover and put it in the well-ventilated area to protect it from being damp and mouldy if it’s idle for a long time or under extreme weather.

Firstly, you need to ensure the decoration style because it will affect the choice of dining set. If it’s modern decoration, you can choose the metal or the glass. If it’s casual and country style, you can choose the wood or wicker product. If you want french and romantic style, you can choose the aluminum product with elegant curves and details.
Secondly, you need to consider the spatial dimensions, which are matched up to the interior design. Apart from that, it is up to your budget.
