What people ask before they buy, answered in one place.
Sixty questions, from dimensions to the warranty. If yours is not among them, ask us in the chat.
What is the seat height range? Will it suit an ordinary desk?
The seat adjusts steplessly from 42 to 50cm, which suits a standard 70cm desk. Full dimensions are in the product images.
Do the armrests flip up? Can the chair be pushed under a desk?
The armrests flip up, so the chair slides fully under a desk and takes up less room.
Can one person assemble it? Are tools and instructions included?
The box includes the tools and a Japanese assembly manual. Following the steps, one person can build it in about 30 minutes.
What size is the carton? Will it fit through a front door?
Before assembly the carton is 56×25.5×53cm. Any front door 60cm wide or more will take it without trouble.
How much does the assembled chair weigh? Can one person move it?
Weight varies by model.
・Round-base model: about 8.4kg
・Rocking model without headrest: about 9.2kg
・Rocking model with headrest: about 9.7kg
All are light enough that, held by the seat frame, one person can move and reposition the chair easily.
How wide and how deep is the seat?
The seat is about 47cm wide and about 47cm deep, comfortable for an average build.
How tall is the backrest? Does it support the head?
Round-base model and rocking model without headrest: the backrest is about 65cm, supporting from the lower back to around the shoulder blades.
Model with headrest: the adjustable headrest extends support to the head.
What is the diameter of the five-star base? Is it stable?
The base is about 60cm across and sits low, so the chair stays steady and does not wobble when you lean into it.
Do the holes ever fail to line up during assembly?
Every unit is inspected before it ships. If a part is not right, send us a photo and we will sort it out quickly.
Are spare screws included? What if I lose one?
We are sorry — no spare screws or spare parts are included. If anything is missing or damaged, send customer support a photo after your order arrives.
Is the mesh back breathable? Does it get hot in summer?
The high-elasticity breathable mesh lets air move freely, so it stays comfortable through long sittings and in summer.
Is the seat cushion firm or soft?
High-resilience foam gives it a middle firmness with spring. It does not sink under you, which suits long working sessions.
Will the mesh stretch and sag over time?
The mesh has high tensile strength and is designed not to sag within normal use.
How do I clean the mesh? Does it collect dust?
Wipe light dust with a dry cloth, or vacuum on a low setting. If you spill liquid, blot it up straight away.
Can the cover be removed and washed?
The mesh is not removable or machine washable. Wipe marks with a damp cloth and let it dry somewhere airy.
Is there a plastic smell when I open the box?
Being new, it may carry a faint material smell on opening. Left somewhere airy for 1-2 days, it fades on its own.
Does the mesh feel cold in winter?
Because the mesh breathes well, it can feel cool in a cold room. A seat pad keeps it comfortable.
Does the fabric build up static?
The material is designed to resist static, though a very dry season may still produce a little.
Will the metal parts rust in a humid room?
The metal parts are rust-treated. Avoid an extremely damp room where condensation is constant and there is no problem.
Can a pet's claws tear the mesh?
The mesh is built for strength, but sharp claws can still tear it. Keep pets from scratching at it.
Does the chair swivel a full 360 degrees?
Yes — the seat turns a smooth 360 degrees, so changing direction or reaching across a desk is easy.
Will the castors scratch the floor? Can I use it on wood flooring?
Quiet PU castors suit both wood flooring and carpet. They are gentle on the floor and roll with little noise.
Is the lumbar support adjustable?
An independent lumbar support adjusts both up and down and forward and back, so you can set the fit to your build and posture.
How far does the rocking function tilt? Can it be locked?
Rocking series: rocks smoothly to about 30 degrees, which is ideal for taking a break. The tension is set by the dial underneath.
Round-base model: a fixed backrest built for stability, better suited to focused work.
Can the headrest be adjusted for height and angle?
Model with headrest: a 3D-adjustable headrest sets freely for height and angle and supports the neck firmly.
Model without headrest: no headrest is included with this model.
Will my back ache after sitting a long time? Is it ergonomic?
An ergonomically shaped backrest and adjustable lumbar support reduce the load on your lower back. Do still take regular breaks.
Is it suitable for eight hours a day of working from home?
It is designed for long stretches — home working, study, gaming — balancing airflow with support.
Can it be used as a gaming chair?
The rocking function and full-body support keep you comfortable through a gaming session too.
How do I set the rocking tension? Where is the dial?
The dial sits at the front of the mechanism under the seat. Clockwise firms the rocking, anticlockwise loosens it.
Does the front edge of the seat press uncomfortably on the thighs?
The front edge curves away gently, easing pressure behind the thighs so long sittings tire you less.
Does it work for shorter and taller people? What height range does it suit?
The seat height range is wide, comfortable for people from roughly 150cm to 185cm.
Do the castors roll smoothly on carpet?
On a thin carpet they roll smoothly. A thick, long-pile carpet will add noticeable resistance.
Will the chair roll away on its own? Do the castors lock?
The castors have no lock, but they carry enough resistance that the chair does not roll away on its own.
Is it safe for children to climb on and play?
Use it only with an adult present. Children climbing or rocking it unsupervised risk tipping the chair over.
Can I stand on the chair to reach something?
Never stand on the seat — it risks tipping and damage. This is furniture for sitting on only.
Can I sleep in it with the backrest rocked back?
It suits a short rest, but it is not designed as a bed for sleeping through. Please use it as an office chair.
What is the weight limit?
The recommended limit is 150kg. A reinforced nylon base and a standards-compliant gas cylinder keep it stable.
Is the gas cylinder safe? Could it burst?
We use a reinforced gas cylinder that meets safety standards and is pressure-tested before shipping. In normal use it is safe.
Can it develop a creak in use?
Tightening the screws evenly during assembly prevents most noise. If a creak appears later, retighten them.
Does the chair lean to one side or feel wobbly?
Assembled correctly it neither leans nor wobbles. Use it on a level floor.
Will the cushion flatten after years of use?
The one-piece moulded high-resilience foam resists flattening over long periods of normal use, holding its comfort.
Do the armrests wobble? Can I put my weight on them?
The armrests are solidly fixed and take a reasonable amount of weight without trouble.
Will the backrest break if I lean back hard?
The structure is designed and verified for strength. Within normal use there is no problem.
Is the base likely to crack?
The five-star base is high-strength nylon with excellent load capacity and durability. Breakage in normal use is rare.
Which chairs does Bestis make, and how do they differ?
There are two main series.
1. Round-base series: a fixed backrest built for stability, aimed at focused work.
2. Rocking series: adds a reclining action for relaxing, and comes with or without a headrest.
Should I choose the rocking model or the fixed one?
If you mostly sit to work or study and want to stay focused, take the round-base model. If you like to lean back between tasks, take the rocking model.
Do I need the headrest? Is it worth having?
If you want neck support, or somewhere to rest your head on a break, choose the headrest version. If you prefer a simpler look, the model without one is comfortable enough.
Can a headrest be fitted to the round-base model later?
This model is not built to take a headrest afterwards. If you want one, buy the rocking model with headrest instead.
Are other colours available?
Black is the only colour at present. It is a plain design that settles into any interior.
Will the chair look a different colour from the photographs?
Lighting and monitor settings can shift the colour slightly. There is no significant difference from what you see.
Do you ship from within Japan? How long does delivery take?
We ship from a warehouse in Japan. Delivery normally takes about 2-5 business days after dispatch.
What should I do if the chair arrives damaged?
If anything is damaged or missing on arrival, photograph it and contact customer support promptly. We will deal with it quickly.
Can I return or exchange it? Who pays the postage?
For a return by choice, the postage is yours. Where the fault is ours — a defect on arrival or transit damage — we cover it.
How long is the warranty, and what does it cover?
The standard quality warranty runs 12 months. It covers defects on arrival and part failures under normal use. Ask support for details.
If a part fails, can I buy just the replacement?
Within the warranty, we send replacement parts free of charge for defects and transit damage. Contact customer support for details.
I want to buy it as a gift — is the packaging presentable?
It ships in a plain cardboard carton. We do not offer gift wrapping, for which we apologise.
Can you issue a receipt?
We can issue an electronic receipt. Contact customer support with your order details and we will send one over.
I am not good with flat-pack furniture — is it hard to build?
The manual has a photograph for every step and the tools are in the box, so a first-timer can put it together easily.
Are the parts interchangeable with other brands of chair?
We have not verified compatibility with other makers' products. If something fails, we recommend genuine parts.
Any tips for making the chair last?
Avoid heavy impacts, retighten the screws from time to time, and keep it out of direct sunlight and hot, damp conditions.
