Looking for the best office chair for a tall person in the UK or an office chair for heavy people? Start by comparing seat depth, seat height, backrest dimensions and the manufacturer's weight guidance.
A chair that looks suitable may still be the wrong fit if its seat is too short, its backrest does not accommodate your torso or its recommended weight limit is below your requirements.
The Boulies EP600 is a strong option for taller users who want adjustable seat depth and backrest height.
The OP180 is particularly relevant for heavier users, with a recommended long-term weight of up to 135 kg and a maximum supported weight of 160 kg.
The OP200 offers a wider seat and independently adjustable lumbar support, while the Master Max has a larger frame, wider seat & taller backrest.
This guide compares the Boulies EP600, OP180, OP200 & Master Max using available manufacturer information.
It explains the differences between maximum and recommended weight capacity, identifies the measurements to check before buying, and helps you choose an office chair that suits your height, weight and working habits.

Maximum Weight Capacity vs Recommended Weight Capacity
- Maximum weight capacity refers to the maximum supported load stated by the manufacturer.
- Recommended weight capacity for long-term use refers to the weight limit the manufacturer recommends for regular, ongoing use.
What Makes a Good Office Chair for Tall and Heavy People?
A suitable ergonomics office chair for tall and heavy people should match the user's body dimensions, provide useful adjustments and meet the manufacturer's weight recommendations.
These are the main features to compare before buying.
1. Adjustable Seat Depth and Thigh Support
Seat depth determines how much of your thighs the seat supports.
Taller users often have longer legs, so a seat that is too short may leave part of the thighs unsupported. However, a seat that is too deep can press against the backs of the knees or prevent you from sitting fully against the backrest.
A sliding seat allows you to move the seat forwards or backwards to find a better fit.
2. Seat Width and Space for Larger Body Types
Seat width matters for people with broader hips, thighs or larger body frames.
A suitable seat should provide enough usable space without its edges or armrests pressing uncomfortably against the body.
When comparing an office chair for big people, check the usable seat width and the space between the armrests. The overall chair width is not the same as the width of the seat itself.
3. Seat Height and Leg Position
Seat height affects how your feet, thighs and arms align with your desk.
A suitable adjustment range should allow your feet to rest on the floor or on a suitable footrest, while providing appropriate support beneath your thighs.
Taller users may need office chairs with a higher seat-height range. However, a higher seat is not automatically better: your leg length, desk height and ability to keep your feet supported also matter.
The Boulies EP600 reaches a seat height of up to 58 cm according to the collection information. The OP180 has a published seat-height adjustment range of 44–51 cm.

4. Backrest Height and Adjustment
Backrest height is particularly relevant for users with longer torsos.
A backrest that is too short may not reach the upper-back area where the user expects support. A taller backrest or adjustable backrest height can provide additional flexibility.
- The EP600 offers 70 mm of backrest-height adjustment.
- The OP180 has an adjustable backrest-height range of 56–63 cm.
- The Master Max has a taller backrest than the standard Master, making it a relevant option for users who prefer a larger chair.
5. Lumbar Support
Lumbar support is designed to support the lower-back area while sitting.
Its position and adjustment range can influence how well the chair fits your body. People with different torso proportions may prefer different support positions.
The four Boulies models use different approaches:
- EP600: 4D adaptive lumbar support with 50 mm of height adjustment and 40° of angle adjustment.
- OP180: Curved backrest design; an independently adjustable lumbar mechanism is not listed in the current comparison information.
- OP200: Independently height-adjustable lumbar pad.
- Master Max: Built-in lumbar support with vertical adjustment.
More adjustment options do not automatically make a chair better for everyone. Consider which type of support you prefer and whether its position can be adjusted to suit your body.
6. Adjustable Armrests
Armrests influence how comfortably you can position your forearms while working.
Ideally, your shoulders should remain relaxed and your forearms should be supported without forcing your arms outwards or upwards. Armrests that are too high or too wide may also prevent you from sitting close enough to your desk.
- The EP600 has 6D adjustable, flip-up armrests.
- The OP180 and OP200 have 3D adjustable armrests.
- The Master Max has 8-way adjustable armrests.
Check the actual adjustment directions and range rather than comparing the number of adjustment dimensions alone.
7. Reclining and Seat-Tilt Mechanisms
A reclining backrest and a tilting seat perform different functions.
A reclining backrest changes the angle of the backrest in relation to the seat. A seat-tilt mechanism changes the angle of the seat itself.
- The Boulies OP180 offers backrest recline between 79° and 103°, alongside 2° forward seat tilt and 10° backward seat tilt. Both seat-tilt positions can be locked.
- The OP200 offers four locking backrest positions: 98°, 105°, 114° and 120°. Its recline function does not provide the same forward and backward seat-tilt adjustment as the OP180.
- The EP600 reclines up to 120° with a position lock.
- The Master Max offers full backrest recline and a 15° rocking function.
8. Upholstery and Construction
Upholstery affects the feel and breathability of a chair, while its frame, base, gas lift and tilt mechanism form part of its construction.
- The OP180 uses an Airy Mesh backrest and cold-cured foam seat.
- The OP200 has a breathable mesh backrest and thick foam seat cushion.
- The EP600 uses Airy Chenille Hybrid Mesh upholstery.
- The Master Max uses 100% cold-cure foam.
For heavier users, the manufacturer's published weight guidance remains essential. A heavy-duty gas lift, reinforced frame or sturdy-looking base should not be treated as a substitute for a confirmed weight capacity.

How to Measure Yourself Before Buying an Office Chair
Measuring your body and comparing those measurements with the manufacturer's specifications can help you avoid choosing a chair that looks suitable but does not fit your proportions.
1. Check Your Seated Height and Torso
Your overall height does not tell you everything about the backrest you need.
Two people who are both 185 cm tall can have different leg and torso proportions. One may need more seat depth, while the other may need a taller backrest.
Compare your seated torso and shoulder position with the BOULIES product backrest and headrest dimensions.
2. Measure Your Leg Length
Pay attention to the distance from the floor to the back of your knee while seated.
This helps you assess the seat-height range needed to position your feet properly. Consider your usual footwear and desk height when checking the adjustment range.
If your feet cannot reach the floor after adjusting the chair, a suitable footrest may be necessary.
3. Measure Your Thigh Length
Measure from the back of your hips to the area just behind your knees while seated.
Use this measurement to assess whether the seat depth provides enough thigh support without pressing against the backs of your knees.
If you have longer thighs, a chair with adjustable seat depth may be particularly useful.
4. Measure Your Hip Width
Measure the widest part of your hips while seated.
Compare this with the usable seat width and armrest spacing shown in the manufacturer's dimension diagram.
Do not use the overall chair width as a substitute for seat width. The overall figure may include the armrests, frame and backrest.
5. Check Your Desk and Workspace
A chair should fit your desk as well as your body.
Check your desk height, the clearance underneath it and whether the armrests allow you to move close enough to the work surface.
Also consider whether the chair can move freely within your workspace.

Seat Width vs Seat Depth: What's the Difference?
Seat width and seat depth measure two different aspects of an office chair.
Seat width measures the usable space from one side of the seat to the other. It is particularly relevant for hip and thigh clearance.
Seat depth measures the distance from the front edge of the seat to the backrest. It determines how much of your thighs the seat can support.
A chair can have a wide seat but a relatively short seat depth. A deep seat does not necessarily provide enough room across the hips.
For this reason, taller and heavier users should check both dimensions independently.

Boulies offers different chair designs for users who need additional adjustment, more seating space or published weight guidance.

How to Choose an Office Chair for Long Working Hours
Choosing an office chair for extended desk work involves more than selecting the model with the highest weight capacity or the largest number of adjustments.
The chair should fit your body, work with your desk and allow you to change your sitting position when necessary.
The UK's Health and Safety Executive recommends adjusting a workstation so that the chair supports the thighs, the lower back is supported and there is a small gap between the front of the seat and the backs of the knees.
Read the HSE guidance on good posture when using display screen equipment.
1. Adjust the Seat Height
Set the seat height so that your feet are supported on the floor or a suitable footrest.
The seat should support your thighs without putting excessive pressure behind your knees.
2. Set the Seat Depth
Sit with your back against the backrest and adjust the seat so that it does not press against the backs of your knees.
The HSE recommends a gap of approximately 2–3 cm between the front of the seat and the back of the knee.
3. Position the Lumbar Support
If your chair has adjustable lumbar support, position it where it meets your lower-back area comfortably.
Do not assume that the highest or deepest setting will suit everyone.
4. Adjust the Armrests
Position the armrests so that your shoulders remain relaxed and your forearms are supported naturally.
Also check that they do not prevent you from moving close enough to your desk.
5. Change Your Sitting Position
Even a well-fitted office chair should not encourage you to remain in exactly the same position throughout the day.
Change your sitting position and take regular movement breaks as part of your working routine.
Common Mistakes When Buying an Office Chair for Tall and Heavy People
Choosing a chair based on appearance or one headline specification can lead to a poor fit.
Avoid these common mistakes before placing an order.
1. Ignoring Usable Seat Width
A chair can have a suitable weight rating and still feel restrictive if the seat or armrest spacing is too narrow.
Check the usable seat width rather than relying on the overall chair width.
2. Assuming More Adjustments Always Mean a Better Fit
A chair with six-dimensional armrests or several lumbar adjustments is not necessarily the right choice for everyone.
The important question is whether those adjustments address your actual seating requirements.
3. Ignoring Desk and Workspace Dimensions
A chair that fits your body may still be unsuitable for your workspace.
Check desk height, legroom, armrest clearance and available floor space before purchasing.
