Thanks to its ability to adjust to different needs, this folding furniture can go from a small table to a much larger one in a matter of seconds. But have you ever wondered how the opening mechanism of an extendable table actually works? The secret lies in the type of system that allows the furniture to be easily extended and folded.

Therefore, in today’s article we are going to explain the different types of opening that our expandable tables have and which one you should opt for if you want to adapt 100% to the available space on your terrace.

Types of Mechanisms for Extendable Tables
In today’s garden table market, there are several opening mechanisms that allow this outdoor accessory to be easily opened and transformed to gain space. Here are the most common ones and how they work:

1. Extendable up&down table mechanism
The opening system of the extendable up&down tables combines maximum quality with functionality. To extend them, simply open both sides of their internal structure and pull them up with a gentle movement to fully unfold the furniture.
This opening and closing mechanism is ideal for multifunctional spaces, where you can get a large dining table or even a comfortable and practical work table.
2. Table mechanism with side extension
The extension of this table is located on one or both sides of the furniture. In other words, the product has built-in extensions that unfold without the need to add additional parts. To open the table, you just have to extend one of the sides and remove the extension using guides. Tables with this mechanism are ideal for multifunctional spaces and small spaces, with the possibility of folding their surface just by stretching one side.

3. Butterfly folding table mechanism
The butterfly mechanism refers to a folding system where the table extension is stored under or in the center of the table surface and easily unfolds when needed. The extendable part is hidden in the center of the table and, when it needs to be expanded, it unfolds as if it were a “butterfly”, spreading its wings to both sides.
This mechanism is usually integrated into the central structure of the table and is very practical and easy to operate. For this reason, it is usually the star extendable table that we find in most outdoor spaces or dining rooms.
4. Extendable table mechanism with sliding or sliding legs
This mechanism is one of the most common in extendable tables and its main feature is that the legs slide to allow full extension. To do this, this type of table is usually made up of one or more hidden extensions, either in the center or on the sides. To open it, it is as simple as sliding the legs along a guide or rail, allowing more skillful surface to be added manually.
The main benefit is that, by sliding the legs along with the table surface, they are always kept at the ends of the table, achieving the great advantage of not having any legs between diners in their most extensive position, as well as guaranteeing greater stability. For this reason, it is usually the ideal table model for those who have a large terrace and require a greater capacity when there are many guests.

Factors to Consider When Choosing the Mechanism for an Extendable Table
When buying your extendable table, it will be crucial to take into account some factors to ensure that the mechanism is suitable for your needs and space. Notes!

1. Frequency of use
If your outdoor table is going to be extended longer than folded, make sure you choose an extension mechanism that is practical and easy to handle. Sliding systems with concealed or butterfly extensions are ideal for regular use, as they are quick and easy to assemble and disassemble.
2. Size and capacity
Depending on the number of diners you usually receive, you will need a mechanism that allows you to expand the table enough so that everyone can fit in without problems. If, as a general rule, your guests do not usually exceed 10 diners, an extendable up&down table will be enough. However, if your lunches and dinners usually accommodate 14 or more people, sliding leg mechanisms are ideal for larger tables. The latter provide you with better weight distribution and greater stability.

3. Espacio disponible
En terrazas y jardines de gran amplitud, todos los mecanismos para mesas extensibles serán aptos y funcionales. Pero, para espacios más pequeños o tipo balcón, las mesas plegables en formato mariposa son una excelente opción. Aunque, también puedes optar por una mesa pequeña que se haga más grande gracias a algún otro sistema compacto de extensión. De esta manera, tu mesa plegable no ocupará espacio de más cuando no sea necesario. ¡El modelo Osaka o Tokio de 80 x 80 cm seria una magnífica opción!
4. Estabilidad
La estabilidad es clave, especialmente en mesas que se extienden para muchos comensales. Desde Defora Home te aconsejamos optar por mecanismos de apertura robustos como el de patas deslizantes, para asegurar que el producto no se tambalee cuando esté completamente extendido.
