A recliner is a type of chair designed for ultimate comfort and relaxation, featuring a mechanism that allows the user to adjust the chair’s position for better support. Here’s a detailed description:

**Design and Mechanism:**
- **Reclining Feature:** Recliners come with a built-in mechanism that allows the backrest to tilt backward while the footrest extends, enabling users to find a comfortable, semi-horizontal position.
- **Adjustability:** Most recliners have multiple reclining positions, including a full recline for sleeping or lounging and a more upright position for reading or watching TV.
- **Power or Manual:** Recliners can be operated either manually, with a lever or handle, or electrically, with a button or remote control. Power recliners often include additional features like lumbar support and adjustable headrests.

**Comfort and Padding:**
- **Cushioning:** Recliners are typically heavily padded with high-density foam or other materials to provide excellent support and comfort. The cushioning is often found in the seat, backrest, and armrests.
- **Ergonomic Design:** Many recliners are designed with ergonomic considerations, including lumbar support and contoured seating to enhance comfort.

**Upholstery and Materials:**
- **Fabric Options:** Upholstery can vary from luxurious leather and faux leather to cozy fabrics like microfiber, chenille, or velvet. Each material offers a different feel and aesthetic.
- **Durability:** The choice of upholstery affects the durability and ease of maintenance. Leather, for example, is often durable and easy to clean, while fabrics may offer more variety in terms of texture and color.

**Size and Style:**
- **Dimensions:** Recliners come in various sizes, from compact models suitable for smaller spaces to larger, more expansive designs. The size of the chair can affect its functionality and placement in a room.
- **Styles:** They are available in a range of styles, including traditional, contemporary, and modern designs, to match different decor preferences. Some recliners also feature additional elements like built-in cup holders, storage compartments, or massage functions.

**Additional Features:**
- **Heat and Massage:** Some advanced recliners include built-in heating elements and massage functions, providing an enhanced relaxation experience.
- **Swivel and Rocking:** Some recliners come with swivel or rocking capabilities, adding to their versatility and comfort.

**Construction:**
