Details of the sizes of different types of sofas

The sofa is firmly associated with homeliness and comfortable rest. Often, it is enough to purchase and install upholstered furniture so that the room is completely transformed and acquires a special flavor. It is this symbol of bliss and luxury that becomes the visual center, the focal point in the living room interior, adds softness and sophistication to the strict lines of a modern kitchen, and has a calming effect in the hallway or loggia.

Sofas do not go out of fashion, remaining relevant in the 21st century. Manufacturing factories offer new design solutions, combine different functions, improving their products. And consumers can only choose the most suitable model.

One of the main parameters is the correct dimensions of the product. Today we will talk about the classification of upholstered furniture by size. We'll give you tips on choosing the right size sofas.

How to measure the standard height of a sofa from the floor

To determine the exact dimensions of the product you like, measurements must be taken directly from the floor. The beginning of the ruler or tape measure must be pressed to the floor surface next to the furniture, holding the measuring tool strictly perpendicular. Measure to the top edge of the seat if you are measuring the seating area, or to the top edge of the backrest if you need to determine the overall height. If the backrest includes pillows, then measurements need to be taken to their top.

Important! However, the armrests are measured from the top of the seat, from the middle of its depth - where it is pressed down the most

Mechanisms of transformation

In order to avoid difficulties with turning a sofa into a bed during daily use, you need to pay attention to the transformation mechanism - folding out. The service life of the sofa depends on it. When choosing a transformation mechanism, you need to take into account the location of the sofa - living room, bedroom or children's room

Below we consider common mechanisms and their features.

When choosing a transformation mechanism, you need to take into account the location of the sofa - living room, bedroom or children's room. Below we consider common mechanisms and their features.

Book and Eurobook

The mechanism of the “Book” is a spring block. The Eurobook does not have a mechanism.

Pros:

• suitable for daily sleep;
• has a durable mechanism that is considered eternal;
• occupies the same area both when unfolded and folded;
• models are equipped with drawers for bedding.
• Suitable for a one-room apartment, a children's room, for a teenager, for use in the country.

Minuses:

• reclines only in sitting and lying positions;
• requires free space between the back of the sofa and the wall;
• Not all models have armrests.

The difference between “Book” and “Eurobook”:

The “book” is folded out by tilting the backrest. The Eurobook unfolds in a different way: the seat rolls forward using special rollers and the back of the sofa fits into the free space, turning it into a sleeping place.

Click-clack

This model is a type of book.

Pros:

• a child can handle the transformation of a sofa into a bed;
• large surface for sleeping;
• has armrests and drawers for storing linen;
• may have additional equipment in the form of a small table or shelf.

Cons: the service life of the mechanism is limited to 7 years.

How it unfolds: when you pull out the front part of the sofa, the second part of the structure, which is hidden inside the sofa, will “emerge” from below. It should be raised up to the level of the seat to create a flat sleeping area.

Saber

A sofa bed with this name would be an excellent solution for a children's room due to its unusual roll-out mechanism.

Pros:

• there is a drawer for linen,
• There are mini-lifting models for children and models for adults,

How to unfold: you need to pull the hinges that the sofa is equipped with. The sections roll out one after another, like a telescope.

Filling and upholstery

The filler is one of the most important components of the sofa.

For seat cushions in sofas, either foam rubber or springs are used. Foam filling is cheaper, but loses its original shape after several years of use.

Furniture foam rubber or polyurethane foam is the main soft filler of upholstered furniture

Spring mattresses are more expensive and must rest on a more massive base.

Sofas are upholstered with a variety of materials. Leather upholstery has become the standard for office upholstered furniture. For the living room, upholstery made from tapestry, a semi-synthetic material with water-repellent impregnation, is well suited.

Interior design experts unanimously recommend choosing neutral colors for upholstery in the living room that will not attract attention.

Beige corner sofa with brown inserts

One of the most common color options for a modern living room is many shades of gray.

If you want to add brightness, it is better to do this with the help of replaceable capes and decorative pillows.

Bright accents on pieces of furniture or decor are necessary to create a harmonious picture of the interior

By carefully considering the choice of the sofa model you need before purchasing it, you will avoid possible disappointments, and the new sofa in your living room will delight you and your guests for many years.

Non-standard models

Mini and maxi dimensions are classified as non-standard. There are many options for such cabinets. To produce them, specialists use 3D modeling. This allows you to create the most accurate option for a specific room.

Massive cabinets deeper than 500 mm and above 1500 mm require additional supports. The mezzanines of such compartments are made separately. Therefore, optimal designs should not exceed standard sizes. Typical cabinets are connected to each other to form a single line. In this regard, cabinet furniture with varying capacity stands out.

Variable Depth Models

These are designs of the following type: a compartment with shelves with a useful area of ​​60 cm, then a radius compartment with a transition to a body with a depth of 35 cm. Then a transition in the opposite direction is possible, if space allows. Fortuna, Maestro, Ikea, Aristo, Modus and other companies offer ready-made options, as well as accessories for making sliding wardrobes.

An example of a radius wardrobe diagram. View from above.

It is not necessary to be so strict in changing the depth. There are radius structures designed for installation in a corner:

1. Convex - the useful area expands towards the center and decreases at the corners. We manufacture cabinets of various radii. Semicircular models have the most spacious center.
2. Concave - small in volume products. They allow you to fit not a lot of outerwear, jackets, shirts on hangers, but its depth is the same over the entire area and is 35-50 cm.
3. Combined is a combination of the two previous types of models, which are sometimes alternated with direct modules. Such cabinets are installed on the entire wall to accommodate the entire wardrobe. The structure itself will be from 35 to 90 cm deep in different areas.

The corner option is suitable where it is impossible to place other furniture. This saves space and has a positive effect on the aesthetics of the room.

Modular sections can be purchased in different depths

How to choose product dimensions

When choosing the size of your sofa, be judicious. You need to be based on:

• room possibilities;
• interior design;
• the required capacity of the sofa.

The optimal increase for a sofa for each family member is 70 cm when disassembled, 50 when assembled.

In fact, there is hardly enough space on it, so be more wasteful: it is better to buy additional modules or use more spacious models.

In a large family, three-seater corner sofas, one-and-a-half-size fold-out products, etc. are needed. The optimal increase for a sofa for each family member is 70 cm when disassembled, 50 when assembled. Based on this calculation, you can accommodate three people in a double version with a length of about 200 cm. In fact, there is hardly enough space on it, so be more wasteful: it is better to buy additional modules or use more spacious models.

In small rooms, double sofas 1.8-2 meters long are installed.

In small rooms, double sofas 1.8-2 meters long are installed. They can be cut in depth up to 70 cm. Height is 7-8 decimeters. If the size of the apartment allows, it is better to purchase three-seater, corner models. The additional module expands compactly, making such devices a comfortable sleeping place. Its height should be sufficient for a person to feel comfortable while resting.

Designers advise choosing sofas with a high backrest. It visually expands the space around the furniture. However, it should not exceed the level of the window sills in the house.

Sleeping area

The undeniable advantage of modern corner systems is that in terms of functionality they are a universal piece of furniture, and in terms of convenience they are comparable to beds. The most popular models are those in which the sofas are compact in size, but have a spacious sleeping area. This piece of furniture is suitable for sleeping at night and does not take up much space during the day.

Width is the main standard size, according to which corner systems are divided into several varieties. They are presented in the table.

Variety	Length, cm	Width, cm
Single model	150	70
Double sofa	150	150
Three seater sofa	200	250

When choosing, special attention should be paid to such characteristics as the comfort of the sleeping place, the overall dimensions of the corner sofas and their equipment.

Product forms

In addition to a variety of contents, functional pieces of furniture can have classic and original contours, as well as unusual decoration. All models can be divided into several types according to their shape:

• rectangular - standard design with several wide lower drawers and two upper ones, separated by a partition;
• corner - occupy a minimum of space, can have an L-shaped, L-shaped, trapezoidal contours, consist of five walls;
• radius - instead of the usual strict angles, models have convex or concave surfaces, curved shapes;
• combined - chests of drawers with moving modules, relevant in the design of modern interior styles.

There are designer models, which are given an unusual shape, and products are made in non-standard dimensions. The type of installation of the product depends on the shape of the chest of drawers. Furniture can be installed along the walls, placed in a corner, hung on the walls, placed in the center of the room - island options with drawers that slide out in both directions. The dimensions and dimensions of the chest of drawers should be such that the product is comfortable to use in everyday life and to store many things in the drawers.

Project preparation

The sofa-book diagram includes drawings of each part separately and general dimensions of the product .

• Seat – consists of 2 parts: a box for linen and a frame. Slats are attached to the frame. You can also use a plywood sheet as a base, but lamellas are a more convenient and practical option. Even if the box is of medium size, it is reinforced with crossbars - their thickness and the distance between the slats are indicated in the drawing.
• The back is a flat frame and slats. The upper structure is strengthened in the same way as the lower one, since when laid out it acts as a sleeping bed. The frequency of installation of lamellas is the same.
• If homemade furniture has armrests , a template is shown on the drawing indicating the dimensions.

When drawing up a diagram, it is recommended to immediately indicate the location of the attachment mechanism for the layout. Based on the finished drawing, it is easy to calculate the amount of fasteners needed: this can also be immediately indicated on the sketch.

You can use ready-made drawings on relevant websites and forums. But at the same time it is necessary to strictly observe the specified dimensions and proportions.

Main types of models

A corner sofa is a combination of an armchair and a straight section. This configuration makes it possible to rationally use the living space of the room and is great for “blind spots”. The main advantage is that the room creates additional space for relaxing and receiving guests. However, purchasing a corner model requires knowledge of a number of nuances.

The transformable type design is equipped with folding, walking or retractable mechanisms that allow it to be converted into a sleeping sofa by increasing the overall dimensions. The most common are: Eurobook, tango, dolphin, Spartak and so on. These models have many more advantages than disadvantages. A significant disadvantage is the inability to use every day due to design features. In Eurobook and Dolphin mechanisms, for example, the surface of the rolling part is quite hard, but the springy base is much softer - this creates certain inconveniences. The main advantages of transformers:

1. The design quickly unfolds, and this allows you to intelligently use the usable living space.
2. Reliability and durability are ensured by the minimal use of moving mechanisms.
3. More seating can be achieved almost instantly.
4. Internal drawers are great for storing linens - eliminating the need for additional cabinets. This option is especially relevant for rooms with dimensions that do not allow placing a large amount of furniture.

The difference between a modular sofa and other options is that its structural basis is built on the ability to transform through the arrangement of individual segments, making it possible to radically change the configuration. Each component element performs its own function:

• the straight part of the sofa adjusts its length - this way you can free up useful space;
• the angular segment participates in the formation of one or more protrusions;
• armrests separate parts of the sofa from each other;
• Poufs are additional soft seats.

Modular corner systems have a number of advantages:

• the size of the sofa, the number of segments and configuration can be determined independently, thereby deciding which part of the area to leave free;
• almost all modules are equipped with drawers for storing things;
• you can change the shape instantly, freeing up the necessary space in the room;
• armrests can replace bookshelves or a coffee table.

The choice of modular designs for small spaces is very limited. When designing a room, you must strictly follow the rules for choosing corner furniture and take into account the layout features. Products designed for frequent rearrangements are very expensive.

The monolithic design is almost always presented in the shape of a semicircle and is non-removable. This option requires large areas and is therefore very often used in public places or spacious living rooms. The main advantage of the model is its long service life, since the design does not contain transformation mechanisms that can quickly fail. The disadvantages include the inability to unfold and form a sleeping place.

Frame

Corner sofa frame made of chipboard

The durability of a sofa is largely determined by the material from which its base is assembled. The simplest and cheapest ones usually have a frame made of chipboard. You should not buy such a sofa on the market or from an unreliable seller - low-quality chipboard will not only shorten the life of your sofa, but can also emit harmful substances for years. But if the frame is made of high-quality material, then such a sofa should be considered as a good purchase for reasonable money. The most common wood frames are: pine, birch, ash, beech, oak and other species. The highest quality furniture has a frame made of oak beams, which are reinforced with metal elements. Such sofas belong to the highest price category, but their long service life makes the purchase profitable.

Sofas with wooden frames are durable

Sofas with a metal frame stand somewhat apart. Typically office furniture has such a frame. Elements made of chromed steel look good in rooms with high-tech interiors and have a serious margin of safety. The disadvantages of metal frames include their excess weight and high cost.

Non-standard options

Compact and small-sized

Non-standard ones include various small-sized types. Their dimensions are 170 centimeters in width and exactly the same in length. This option is convenient if installation is required in the kitchen or in the hallway.

This type of model folds out very easily, thereby providing a sleeping area suitable for accommodating one person. But it may also have hidden drawers underfoot that are suitable for storing dishes or various household items. This option is often installed in the kitchen.

As a rule, such sofas use universal angles in their design. They can be easily installed on both the right and left sides. This model is not strictly tied to the design specified by the manufacturer.

More compact options are also available.

• The sleeping area of ​​such models is 150 centimeters by 150 centimeters.
• The second option is 130 centimeters by 200 centimeters.

In such rooms there is always a struggle for centimeters, because the bedroom space is limited. This type includes sofas with “tick-tock”, “dolphin” or “Eurobook” layout mechanisms.

Little ones

Often in stores selling furniture you can see models that are quite small in size. Often such designs are a “book”.

If we disassemble such a sofa, we get the length of the sleeping place measuring 125 centimeters by 140 centimeters.

In addition, you can combine such a sofa with another one - measuring 90 centimeters by 168 centimeters. This sofa will serve as an ottoman. Both parts are independent of each other.

Average

Medium-sized corner sofas are widespread and loved by customers.

They have sleeping space parameters of around 200 centimeters by 150 centimeters. This is a recognized standard for upholstered furniture of this class.

If such a sofa is assembled, it will have a length of about 245 centimeters and up to 260 centimeters. This difference depends on the presence of armrests in the design and their width.

The depth of the seat can vary up to 150 centimeters, taking into account the backrest. The height ranges from 70 centimeters to 80 centimeters.

Large

If we talk about large corner sofas, then this class should include models that have a seat length ranging from two meters or more.

They come in both folding and monolithic types. Modular and standard options are available.

Often such sofas are produced according to customer designs in a single copy. As a rule, these models are equipped with various shelves, tables or a small bar that has the ability to cool drinks. This bar is usually located in the middle zone.

The dimensions of the sleeping place can be within 200 centimeters by 140 centimeters and up to 300 centimeters by 200 centimeters.

Configuration and dimensions of radius models

The latest innovations in the furniture market include radius models of corner sofas.

They are produced in the form of a semicircle and look very beautiful, attractive and unusual. Most often, such models are designed in a modern design. In this type of furniture, the laws of such styles as Loft and Techno or Hi-Tech usually prevail, as the most progressive. But no one bothers to ask the manufacturer to make this type in the classic version.

The size of such a sofa will directly depend on the number of segments included in the layout.

If the living space is small, then this type of sofa will be appropriate only if its dimensions do not interfere with the free movement of residents.
