The best option for most people is a flat-seat ergonomic chair, because it gives your legs room without losing back support. You’ll find an office chair that you can sit cross legged in two main shapes: wide flat seats or open disc designs. If you already have chronic hip pain, a physical therapist should guide your choice instead.
Wide seat chairs for sitting cross legged
Four real designs let you fold your legs comfortably at a desk. Each one trades something away to give you that flat space.
| Method | How long to set up | Effort | Cost | Best for |
|---|---|---|---|---|
| Flat ergonomic chair | 10 minutes | Low | High | All-day typing |
| Saddle stool | 2 minutes | Medium | Medium | Short active tasks |
| Disc seat | 5 minutes | Low | Low | Moving around often |
| Kneeling chair | 10 minutes | High | Medium | Lower back relief |
Pick the flat ergonomic chair if you work full days; pick the disc seat if you change rooms often.
Flat ergonomic office chairs
A flat ergonomic chair drops the curved bucket seat so your thighs aren’t pushed together.
- Set the seat height so your hips sit slightly above your knees.
- Push the chair close enough that your elbows bend at 90 degrees.
- Cross one ankle over the opposite knee, keeping your spine straight.
- Switch which leg is on top every 30 minutes.
- Plant both feet flat when you need to reach far across your desk.
This design keeps your lower back supported during long shifts. It’s built for anyone who types all day but hates feeling trapped by armrests and narrow cushions. The trade-off is price — these chairs cost significantly more than standard models. If your floor is thick carpet, check the manufacturer’s guide for the right wheel type before buying.
Active saddle stools
A saddle stool splits the seat into two angled halves, leaving the middle completely open. You perch on it like you’re riding a horse, which naturally opens your hip angle.
- Raise the stool until your thighs slope down at about 45 degrees.
- Sit toward the front edge so your weight rests on your sit bones.
- Cross your ankles loosely underneath the open center gap.
- Shift your weight side to side every 15 minutes to keep blood flowing.
Saddle stools build core strength because there’s no backrest to lean against. They’re ideal for standing-desk users who want a quick seated break without losing their posture. Without lumbar support, they get uncomfortable past the two-hour mark. Don’t use one as your only seat for an eight-hour shift.
Flat disc and floor seats
A disc seat is a firm, round cushion on a short base with no back or sides blocking your legs. It forces you to balance yourself, giving you total freedom to arrange your legs however you want.
- Place the disc on a stable floor or low platform.
- Sit dead center so your weight spreads evenly.
- Fold your legs into any cross-legged position that feels natural.
- Stand up and stretch every 20 minutes to reset your spine.
These cost very little and take up almost no space in a room. They work well for reading, video calls, or short laptop sessions where you don’t need a desk. Sitting this low puts heavy strain on your knees over time. This setup isn’t meant for anyone with existing joint issues.
Picking the right chair for your day
When you’re rushing between meetings, grab the disc seat. It takes zero adjustment, and you can toss it in a closet when you’re done.
If you’ve never worked without a traditional backrest, start with the flat ergonomic chair. It forgives bad posture while you learn to sit differently.
For the absolute best spinal alignment regardless of budget, buy the saddle stool. It demands effort from your core muscles, but it trains you to hold a neutral spine without leaning back.
You’re trading comfort for freedom here. A standard chair locks you in safely; these options free your legs but ask your muscles to do the work.
Rules for any cross-legged seat
No matter which shape you buy, your screen must stay at eye level. Slouching forward to look down defeats the whole point of changing your seat.
Adjust the height so your arms rest parallel to the floor. Check your lower back after 30 minutes — if it aches, raise the seat half an inch.
The American National Standards Institute sets workstation guidelines through its ANSI/HFES 100 standard, which covers how your body should align at a desk. Read your own monitor height off the wall behind your screen to see if it matches.
If adjusting gas cylinders or swapping heavy bases feels risky, a certified office furniture installer handles that safely.

Frequently asked questions
Can I sit cross legged in a normal office chair?
No, standard bucket seats push your thighs inward and block your ankles. You need a flat or split seat to cross your legs without fighting the cushion edges.
Why does my back hurt when I sit cross legged?
It hurts because crossing your legs tilts your pelvis backward. That rounds your lower spine and strains the muscles holding you upright.
How long can I sit cross legged safely?
Limit it to 30 minutes before switching your leg position. Staying locked in one pose longer slows circulation to your feet and stiffens your hip joints.
Is it safe to work cross legged all day?
No, staying cross-legged for eight hours compresses the peroneal nerve behind your knee. Alternate with both feet flat on the floor every half hour.
What happens if I never uncross my legs at work?
Your outer calf goes numb from constant nerve pressure. Over weeks, tight hip rotators pull your pelvis out of alignment and cause chronic lower back pain.
Are kneeling chairs good for sitting cross legged?
They aren’t. Kneeling chairs lock your shins into pads and force your knees into a fixed angle, leaving no room to fold your legs inward.
How high should my desk be for cross legged sitting?
Your wider stance lowers your torso slightly, so the desk needs extra clearance for your thighs.
Conclusion
Cross-legged sitting changes how your weight hits the chair. Pick the seat shape that fits your schedule, adjust the height carefully, and switch positions before your legs fall asleep.
