Ventra Mesh Back Task Operator Chair with Height Adjustable Arms

There are two heights (89cm to 96.5cm or 109.5cm to 123.5cm). Every one is 65cm wide and 60cm deep.

There are 21: Black, Bergamot Cherry, Ginseng Chilli, Maringa Teal, Myrrh Green, Quest Crab, Quest Kelp, Quest Limpet, Quest Mussel, Quest Salt, and 11 more. The swatch beside each name on the product page is a photograph of the actual cloth, so what you see is what arrives.

It is rated to 150kg. Sitting time is rated at eight hours a day, a normal full-time desk shift.

The seat sits at 43cm to 50.5cm. It is on a gas lift, set with the lever under the seat. A desk of around 72cm to 74cm suits that range, which is what nearly every office desk is built to. The seat itself is 47cm wide and 47cm to 51.5cm deep.

Yes, arms are included. Where fitted, they adjust for height, and they come off altogether if you would rather do without. Arm height is 60cm to 67cm from the floor.

Yes, and it adjusts. You can set the support where your own lower back curves rather than where the average back is assumed to curve, which is the difference between a chair that helps and one that nags.

That is a choice on this chair: With Headrest or Without Headrest. It adjusts for height.

Five things: the seat height is on a gas lift, the back and seat recline together on a synchronised tilt, a tension dial sets how hard you have to push to recline, the seat slides forward and back to set the depth, and an anti-shock catch stops the back snapping forward when you release the lock. All of it is worked from levers under the seat, and the instructions in the box say which lever does what.

It arrives flat-packed as standard, with the instructions and fittings in the box. If you would rather not build it, there are two other choices at checkout. Pre-assembled delivery is £15 an item and it turns up built, ready for you to point at the spot. Installation is £17.95 an item and the crew build it and put it where it is going.

Standard delivery is free and usually lands inside a week. If you are in a hurry, express is £4.95 an item and gets it to you within two working days when you order before 5pm. Some of the options on this page are made to order rather than stocked, and those take 10 to 15 working days. The date it will arrive by is on the page and again at checkout before you pay, counted in working days with weekends and bank holidays already taken out.

It carries the manufacturer's warranty. That covers the mechanism for five years and the fabric and foam for two years. If something fails inside the warranty, report it from your order page and we deal with the manufacturer for you.

This one is upholstered to order in the fabric you choose, so it is built for you and cannot be resold. That means no cancellation once we have acknowledged the order, and no return simply because you have changed your mind. Take a moment over the options before you check out. If it arrives damaged or faulty that is a different matter and your rights are untouched: report it from your order page with photographs and we will put it right.

The everyday office chair: gas lift, a back that tilts or locks, castors, contract fabric. It covers the broad middle of office life without the price of the specialist ranges. There are 46 of them here from £48, and for most people doing most jobs a well-made one, adjusted properly, does everything needed.

Degree rather than kind. A task chair adjusts for height and usually tilt. An ergonomic chair adds independent seat and back angles, adjustable lumbar, seat depth and multi-adjustable arms, so it can be set for one person properly rather than set roughly for anyone. If a chair is shared across shifts, a task chair is often the better buy; if one person sits in it all day, the ergonomic one pays for itself.

Seat height first, so feet are flat and knees are at about a right angle. Then the desk, or a footrest if the desk cannot move. Then the backrest height so the lumbar curve meets the small of your back, and finally the tilt tension so the chair pushes back without launching you. Most discomfort blamed on a chair is a chair nobody adjusted.

Mesh moves air, so it suits people who run warm and rooms that do. Fabric feels softer and warmer and hides wear better. Neither is more supportive by default: that comes from the lumbar and the mechanism, not the material.

The ones here are rated at eight hours or, on a few models, twenty-four. That rating is on every page, and it is the single most useful number when you are comparing two chairs that look alike.

Yes, on everything here. The crew deliver it, build it, put it where you want it and take the packaging away. It starts at £17.95 an item and the exact price is on each product page. Installs usually happen within about 10 working days, and the team agree the day with you rather than simply turning up.

37 of the 46 products in this category have a 3D model on the page rather than only photographs. The viewer spins the actual model, and changing a colour or a size on the page changes the model with it, which is worth doing before committing a whole room to a finish.

Yes. For twenty items or more, or anything with a complication like a mezzanine or a lift that argues back, we plan the job and give you one quote covering the goods, delivery and installation. Ring 0208 138 0512 or email [email protected] with a rough list or a floor plan.

Start with how long it is sat in. A chair rated for eight hours is built differently from one rated for two, and the rating is on every product page. Then the person: weight rating, back height and whether the arms need to adjust. Then the room. There are 218 chairs here from £3, so the filters are usually quicker than the scrolling.

That the chair is built to be sat in by different people all day, every day, rather than by one person in the evening. It shows up in the foam, the mechanism and the fabric rub test rather than in the photograph, and it is the reason an office chair costs more than a similar-looking one from a domestic shop.

The number of hours a day the maker builds the chair to take. Eight hours is a full-time desk chair. Two to six hours covers visitor, meeting and breakout seating. Twenty-four hours means shift work: control rooms, dispatch desks, anywhere the chair never gets to cool down. Ratings across this category run from two hours to twenty-four.

Yes. Checkout asks you to confirm that you are buying for your business, trade or profession rather than as a consumer, and it asks for a company name. That is why prices are shown without VAT and why the terms read the way they do. Sole traders and home-based businesses count, and so does an employer buying a desk for somebody working from home.

No. Every price on the site is shown excluding VAT, because most of our customers reclaim it. VAT is added at checkout and the total you actually pay is on screen before you confirm anything. A VAT invoice follows once the order is complete. Our VAT number is GB 525 3667 81.

Payment is due in full when you order, and the methods available to you are shown at checkout. If you pay by bank transfer, your order is not accepted and the lead time does not start until cleared funds reach our account, so it is worth sending it the same day.

No. We take payment before the order goes to the supplier, so there is no credit account to open and no application to fill in. It keeps our prices where they are, and it means nothing is waiting on a credit check while you are waiting for furniture.

Yes. There is a Purchase Order Number box at checkout, and what you type there carries through to the paperwork so your accounts team can match it up.

No, you can check out as a guest. You will still be able to see the order afterwards: go to Track Order, give the order number and the delivery postcode, and you get the same order page an account holder sees, with the same buttons for returns, cancellations and damage reports. Making an account simply saves typing the address again next time.

Standard delivery is free on everything, whatever the size of the order. The paid options are upgrades on top of that: express, pre-assembled and installation, each priced per item and shown on the product page before you add anything to the basket. Where an option is not shown on a product, it is not available for that product.

We deliver across mainland UK. A number of postcodes sit outside the standard service: Northern Ireland, the Scottish Highlands and Islands, the Isle of Man, the Channel Islands, the Isle of Wight and the Isles of Scilly. We can usually still get furniture to those places, but it has to be quoted rather than booked from the site, so ring 0208 138 0512 or email [email protected] before you order.

Standard delivery is to the door, flat-packed. If you want it carried in and built, choose pre-assembled delivery or installation on the product page. Whichever you pick, the crew ring roughly 30 to 60 minutes before they arrive, so you are not waiting by the window all morning.

Yes, but not on the day. Our courier partner Furdeco plan their routes in advance, so the three hour slot cannot be moved once the van is out. To rebook for another day, ring Furdeco on 0121 285 5255 with your tracking number and pick a time that suits you. Larger deliveries and installations get a call from our logistics team first anyway, so the day is agreed with you rather than sprung on you.

Yes, and it is worth doing. There is a box on the delivery step at checkout, 500 characters, for anything the crew needs to know: where a lorry can park, which floor you are on and whether there is a lift, loading bay hours, a gate code, a one-way system the satnav has never heard of, and who to ask for. It travels with the order rather than sitting in a note at our end. It cannot be edited once the order is placed, so if something changes, ring 0208 138 0512 with your order number.

The courier team will contact you to arrange another date, or you can ring Furdeco on 0121 285 5255 with your tracking number and rebook it yourself. Worth avoiding if you can: a failed delivery costs from £10 an item, plus storage if the order has to go back to a warehouse. A gate code in the delivery instructions box costs nothing.

Yes, we run a removal and recycling service, quoted per job. It has to be booked before delivery day, because the crew can only take away what they have been booked and equipped to take. Tell us what is going when you order and the swap happens in one visit rather than two.

Tell us within 14 days of receiving it and we will look at it. Go to your order page, either signed in or through Track Order with the order number and delivery postcode, and raise the return there. The goods have to be unused and back in their original boxes, or packed well enough to survive the journey. If you send them back yourself there is no handling charge at all and carriage is at your cost. If you would rather we collected, we may charge up to £35 an item, and we tell you the figure before we collect. Anything you paid for on top, like express delivery or installation, is not refunded, because those services were already carried out.

Ask as soon as you can, from your order page. Before anything is dispatched we can often cancel it, though where costs have already been incurred with the supplier we may deduct those before refunding the balance. Once something has been dispatched it becomes a return rather than a cancellation. Made-to-order items cannot be cancelled at all once we have acknowledged them.

Tell the delivery crew at the door. They note it down and photograph it, and that record is what settles the claim with the carrier later. If you turn the delivery away because of the damage, the crew take the goods with them and we arrange a replacement. If you only spot it after they have gone, open your order, press Report a problem and send photographs, up to six on one report. Do it within five days: carriers stop entertaining a claim once a delivery is more than a few days old. A damage report is counted separately from a return, so a breakage does not use up your 14 days.

A confirmation email lands as soon as you order, and the moment it is on its way you get a dispatch email with a full tracking link. You can also go to Track Order at any time with your order number and the delivery postcode. Your order number starts with DW.

Anything out of stock is hidden from the listings, so if you can see it and add it to a basket, we can get it. The exception is made-to-order items, which are not held in stock by design: they are built for you after you order, and their pages say so.

Ring 0208 138 0512, email [email protected], or use the live chat on the site. If it is about an existing order, have the order number to hand and it will be quicker.
