Buying a Sofa Bed: A Guide to Comfort, Space and Everyday Living

A sofa bed can make your living room, guest room or student flat far more flexible. By day it serves as a seat, by night as a place to sleep. In practice, however, poor purchases are often down not to the design, but to unsuitable dimensions, awkward mechanisms or a cover that’s difficult to keep clean in daily use.

This guide from the Joybuy Product Recommendation Officer highlights the details you should check before buying a sofa bed, a sleeper couch or a corner sofa with a bed function.

Common Pitfalls When Buying a Sofa Bed

1. Only checking the dimensions in seating mode

An extendable sofa needs noticeably more space when it’s pulled out. You also need to factor in walkways, radiators, doors and windows. With a corner sofa that has a sleep function, the depth of the ottoman adds to the equation. If you only measure the width, you may later find that the sleeping surface can’t be fully extended.

Practical tip: Mark out the sofa and the sleeping area on the floor with masking tape. Also measure the distance to other furniture and walls.

2. “Sleep function” doesn’t tell you about the actual sleeping surface

A sofa may be able to lie flat, but still offer only a narrow or uneven surface. So always check the specific dimensions in bed mode. For occasional overnight guests, a compact surface is often fine. For regular use, an even cushion, sufficient length and a sturdy sub-frame are far more important.

3. Care promises are too vague

Claims like “easy care” are no substitute for real information about the cover. What matters is the material, whether there’s a zip, whether the cover is removable, and what cleaning method is allowed. If you have children or pets, a washable cover can be a real practical advantage. Even so, liquids should be mopped up promptly – water-resistant properties are not the same as being fully waterproof.

The Parameters You Need to Settle Before Buying

Dimensions, sleeping surface and room layout

Compare at least the following details:

  • Width, depth and height in seating mode
  • Dimensions when fully extended
  • Sleeping surface length and width
  • Seat height and seat depth
  • Space needed in front of the sofa for the pull-out or folding mechanism

A sofa for small spaces shouldn’t just look compact – it should also be able to turn into a guest bed without you having to move other furniture. For larger living rooms, a corner sofa with a bed function can offer more seating and sleeping space, but it will need a bigger footprint.

Mechanism and frequency of use

Folding sofas with an adjustable backrest can usually be converted quickly from seating to sleeping. If you plan to use a sofa bed every day, check whether the mechanism is designed for frequent conversion and whether it can be operated without too much effort.

A 3-in-1 sofa solution can offer several positions – for example, upright sitting, a relax position and flat lying. This flexibility is handy, but it doesn’t replace checking the frame, feet and weight capacity.

Cover, cushioning and stability

For everyday use, the following details are worth looking at:

  • Upholstery fabric – for example, chenille, velvet or linen-look
  • Removable and washable cover
  • Frame material
  • Type of cushioning – for instance, foam, sinuous springs or pocket springs
  • Maximum weight capacity as stated in the product details
  • Assembly effort and what’s included in the delivery

With a sofa with storage, also check whether bedding, blankets or pillows will actually fit inside the compartment. A hydraulic storage box can make access easier, while side pockets are better suited to smaller items.

Buying Checklist for Your Order

Before you buy a sofa bed, these points will help:

  1. Measure the room: Check the seating and sleeping positions, including space to move around.
  2. Compare the sleeping surface: Pay attention to length, width and any unevenness.
  3. Define the purpose: Guest bed, daily bed or occasional relaxation function.
  4. Check the cover: Compare cleaning instructions, removability and material.
  5. Check stability: Consider the frame, feet, mechanism and stated weight limit.

  7. Note safety information: Use the furniture as intended, check connections regularly and do not let children play unsupervised with the mechanism.

Frequently Asked Questions About Sofa Beds

How much space does a sofa bed need when it’s pulled out?

That depends on the construction. A folding sofa usually needs less side space than an extendable one, but the depth can increase significantly. You should compare the manufacturer’s figures for bed mode with your floor plan.

Is a sofa bed suitable for daily use?

A sofa with a bed function can certainly be used more often. Whether it meets your personal requirements depends on the sleeping surface, cushioning, sub-frame and conversion mechanism. For daily sleeping, the flat surface should be checked particularly carefully.

How can you extend the life of a sleeper couch?

Avoid putting excessive weight on the armrests and backrest, follow the care instructions for the cover, and check screws, feet and hinges regularly. The sofa should only be used in accordance with the manufacturer’s instructions.
