FlexiSpot has impressed me over the years with its low-priced office chair range, and this is one of the cheapest I've seen. Considering the low cost, you're getting some good features here, including 4D armrests, headrest, and adjustable lumbar support. For me, at this price it's a no-brainer.

This is a clever design for those who need an office chair for the home office, since it folds down to be stowed under your desk when not in use. With two reclining positions and adjustable lumbar support, flip-up armrests, headrest, and even a footrest, it ticks a lot of boxes in my opinion.

The M59AS offers a host of top features most users are going to want. It's a dual-back design, so the lower back and upper backrests are separate, with the bottom portion offering adaptive dynamic lumbar support that moves with your body for constant support. It also features 3D armrests for finding the perfect spot. Buy a single unit to get the discount.

A budget pick for big and tall users, the M18 from Sihoo is designed for users between 5'6" to 6'2", with a weight load limit of 330lb. The lifetime warranty is a nice bonus (but expect some strings attached). This is a good all-rounder office chair with tilt and recline, adjustable lumbar support, breathable mesh backrest, adjustable headrest, and foam seat cushion. Basically ticks all the core boxes.

The Razer Enki is our top choice office chair for work and play. Designed for gamers, but subtle enough for workspaces, in our 4.5-star review we loved the chair's solid construction, lumbar support, design, and overall comfort. Not quite as cheap as I saw it during the last Amazon sale yet, so watch this space.

This office chair come with adjustable dynamic lumbar support to provide targeted support for lower back pain. With a seat depth of over 20" and leather seating, this chair is designed for comfort and sturdiness. The chair can hold up to 600lbs, and is highly rated on Amazon.

We found the Steelcase Series 2 offered incredible comfort, superb adjustable lumbar support, and 4D armrests that let you really create your ideal working environment. We called this one "comfortable, customizable and compact, but not too costly," in our review.

The EP200 from Boulies is the office chair I use on a daily basis, and I really love it. In my review, I noted that while may lack some of the adjustments found on premium chairs, it's comfortable, supportive, breathable, and looks professional and stylish. I find myself whiling away the hours at work and at play in it. Use code BF90 to get the discount.

This chair is my top pick for those who want long hours of comfort, and features an adjustable headrest, adaptive lumbar support, and 3D armrests. In our review, we called it "a pleasant ergonomic office chair that provides all-day comfort." However, it's not great for taller users. Buy a single chair to get the discount.
