In the description of sofas, there are terms incomprehensible to customers. This is especially true of the materials from which the base for the mattress is made. Modern buyers prefer a frame with lamellas. This is due to the convenience of the design and the benefits that it involves.
What it is?
Lamels are flexible wooden planks with a slight bend. In furniture production, they are also known as lats (latoflex). Less often you can hear the name gnutiki. A set of slats forms an elastic lattice on the frame, which serves as a support for the mattress.
An innovative base on lamellas appeared in 1993 thanks to the German company Froli. It was the German manufacturers who developed and applied shock absorbing elements in the manufacture of furniture. They laid the foundation for the mass production of slatted bed bases.
Wooden slats are endowed with high elasticity and resilience due to the same direction of wood fibers. This quality distinguishes them from hard-to-bend boards, plywood and chipboard. Lamels - although thin, but quite durable plates made of veneer (glued thin wooden sheets).
For a double bed, the installation of 30 slats is considered optimal. A single requires half less. For greater flexibility, some manufacturers place 20 lats for the base 1.90 cm long and two lats more for 2 m. The distance between the lats should not be wider than the plank. Another size can only be in individual cases. The length of the plate depends on the width of the base with a standard width of 8 mm.
Why do we need lamellas for a sofa?
The rack frame in the folding sofa allows you to relax with special comfort. Reiki does not allow the mattress to bend, providing support for the spine and a healthy sleep. Slats in the frame are recommended even for children's sofas.
The advantages of rails in the design.
- Elasticity. Flexible lamellas spring, allowing you to correctly distribute weight and position the spine.
- Noiselessness. Plastic lat holders do not creak, which is important at night.
- Durability. The mattress wears out much more slowly if it lies on the base with lamellas.
- Ventilation. It guarantees airing of the sofa and hygiene.
- Affordable cost.
The lamellas are attached to the frame through the holder. For its manufacture use plastic, polypropylene or rubber. It is mounted on the frame with furniture rivets or staples.
In another embodiment, each of the lamellas is placed in a metal support frame. There are frames with an internal lamella. They initially have holes to secure the holders. Rivets are not needed in this design, which makes it more reliable.
Varieties
Wooden slats are made from various raw materials. For example, oak, beech or birch veneer, treated with a special polymer glue. According to GOST 99-96, a veneer layer of 6–8 mm is required for one latoflex blank.
Beech armor is often used for sofas. This tree is characterized by high strength and decorative characteristics. The rack frame makes maintenance of the mattress easier, providing ventilation, protection from dust and debate, provided that high-quality material is used to manufacture the lat.
If the product is made from wood residues and has noticeable joints, it can quickly become worthless. Especially if you use a bed will be active children.
Selection tips
Birch lamellas are a more affordable option, and poplar and beech are used in expensive orthopedic products. An additional protection is the treatment with a paint and varnish agent.
With the alleged increased loads, the sofa frame is equipped with reinforced lamellas. The arcuate profile provides a light spring effect with pressure on the rails. By distributing the load, they reduce the wear of the orthopedic base and enhance the beneficial effect on the spine.
It should be understood that, despite the strength and resistance to deformation, plywood is susceptible to damage. Of course, replacing the entire wooden grill is an overhead measure. Therefore, it is advantageous to change armor individually.
Replacing them is not difficult without mastery skills, if you act according to the instructions.
How to replace?
The lamels on the base of the berth are not fixed firmly, because otherwise they creak, and the orthopedic effect from them is minimized. Reiki are installed piece by piece, placing in lathe holders. Their presence will prevent creaking.
It is important to know how to put the slats in the frame correctly. The first in the frame install latoderzhateli. How it depends on the type of holder and base of the bed. Holders are aimed at wooden beams or attached to a metal structure with two holes for holders.
After the latent holders are installed, the lamella is taken, slightly bent and inserted first into one hole, then into the second. No need to be afraid of damaging the armor, as they are elastic and strong.
You can replace the lamellas a little differently. First, the latraders are put on the armor, and only then they are mounted in the base.
The dismantling of the lamellas is carried out as follows. Carefully bend the lamella so that the holder comes out of the socket and slide it horizontally to the side.
You can also buy lamellas to existing ones, to improve the base and its greater resistance.
