The biggest mistakes in furnishing a modern office – and how to avoid them

The biggest mistakes when furnishing a modern office are choosing the wrong ergonomic chairs, providing too few adjustable work surfaces, poor lighting, neglected acoustics, and decisions that prioritise looks over function. Over time these mistakes show up as poorer staff wellbeing, more sick leave and lower productivity, so it pays to prevent them already during the space-planning phase.

Heka Interior is the office-furniture brand of Hit Preless d.o.o. from Slovenia, a company that has made furniture since 1986 and employs more than 80 people, with its own production, logistics and installation. Our ergonomic solutions equipped over 1,200 workstations at NLB, and our references include Triglav and Volvo. This hands-on experience furnishing offices large and small is the basis for the advice in this guide.

Why is choosing the wrong office chair the most common mistake?

Choosing the wrong chair is the most common mistake because companies often pick models that look elegant but lack proper ergonomic support. A chair that does not support the lower back and is not adjustable causes back pain, fatigue and reduced focus. Ergonomists recommend chairs with adjustable height, backrest and lumbar support, as only these adapt to different bodies and ways of working.

A simple test helps: a chair the user actually tries in their own workspace before buying rarely disappoints. Read more about the criteria in our guide how to choose an ergonomic office chair and on proper lumbar support.

How many ergonomic chairs does a modern office need?

A modern office needs an ergonomic chair for every workstation where people sit for hours, not just for management. A common mistake is saving on staff chairs while buying expensive executive chairs for a few rooms only. Because employees spend eight hours or more at their desk, a quality chair is an investment that pays off through fewer sick days and higher productivity.

Why are sit-stand desks now a standard rather than a luxury?

Sit-stand desks are now a standard of the modern workplace because they let people switch regularly between sitting and standing, reducing fatigue and static strain on the body. Too few adjustable work surfaces is a common mistake, since the body is not built for motionless sitting all day. An electrically adjustable desk lets each user match the work surface to their height and comfort.

Whether the investment pays off, and how to justify it to management, is explained in detail in our article is a sit-stand desk worth it. You will find our model among the products as CoreLift.

How does poor lighting affect employees?

Poor lighting causes eye strain, headaches and faster fatigue, which directly lowers focus and output. A common mistake is relying only on strong ceiling lighting while ignoring natural light. The best spaces combine daylight, with desks placed side-on to windows, and add adjustable desk lamps so each person can fine-tune their own light level.

Why does too much decoration hurt productivity?

Too much decoration hurts productivity because visual clutter scatters attention and makes a space feel cramped. A common mistake is adding objects at the expense of function. Minimalism is not just a trend but a practical choice: quality materials and clean lines give a room a professional, airy feel. The Heka rule is simple – let the space breathe; the fewer unnecessary objects, the more productive the work environment.

How do you solve noise in open-plan offices?

You solve noise in open-plan offices with acoustic elements and a thoughtful furniture layout, because sound is one of the biggest problems in these spaces. A common mistake is a fully open floor plan with no sound protection at all. Wooden and textile acoustic panels, partitions and quiet zones noticeably reduce echo and distraction, helping employees concentrate and hold calmer phone calls.

• Acoustic partitions between workstations
• Soft sound-absorbing materials (rugs, upholstered furniture)
• Separate quiet zones for focused work and calls

Why is a single undivided space a mistake?

A single undivided space is a mistake because different tasks need different environments. A modern office needs zones for focused work, rooms for meetings and relaxed areas for informal collaboration. A lack of variety forces employees into one single way of working. Lounge seating, meeting tables and quiet booths let the space support the whole flow of the working day.

How do you avoid furnishing without an overall plan?

You avoid furnishing without a plan by taking a holistic approach, planning chairs, desks, lighting and acoustics together rather than separately. A common mistake is buying furniture piece by piece from different suppliers, which leads to a mismatched look and poor functionality. A single partner that advises, plans, manufactures and installs ensures a coherent space and clear responsibility for the result.
