Slide it in
The curve is cut to hug the base of a standard toilet. Push it back until it tucks flush — it lives there and stays out of the walkway.

Sit better.
Sit better.
Go easier.
The human body evolved to squat. A modern toilet asks it to sit, which leaves a bend in the last stretch of the bowel. Goodstool tucks under the bowl, raises your knees above your hips, and takes that bend out.
- Opens the angle. Knees above hips releases the puborectalis muscle, taking the bend from roughly 100° to 132°.
- Less straining. In a four-week trial, the odds of straining fell by 77%.
- Faster. 51 seconds squatting against 130 seconds sitting, in timed testing.
- Tucks away. The curve wraps the base of a standard toilet, so it stays out of the walkway.

Wipe-clean, no upkeep
Getting started
Set up in seconds.
Feet up, knees up
Sit down, then pull it forward with your heels and plant both feet. Your knees should end up clearly above your hips. That's the mechanism.
Lean forward, breathe out
Elbows on knees, long spine, and exhale instead of bearing down. Give it three or four days — the reflex takes a moment to relearn.
How it works
Move the slider.
Move the slider.
Watch the bend open.
The whole idea in one control. Move from feet flat on the floor to feet on a 9″ stool and watch the anorectal angle, the puborectalis muscle and the effort required all change together.

Benefits
What a better angle changes.
Less time seated
Timed testing put squatting at roughly a third of the time sitting took. Less time seated also means less venous pressure on the anal cushions.
Less straining
With the angle open, gravity and normal peristalsis do more of the work. A four-week trial found the odds of straining fell by roughly 77%.
A more complete result
Incomplete evacuation is behind a lot of everyday bloating. The odds of feeling properly empty rose 3.6× in the same trial.
Kinder to haemorrhoids
Those tissues swell under repeated straining. Less straining means less load, which is why so many clinicians start with posture and fibre.
Gentler on the pelvic floor
Chronic straining is a known stressor for pelvic floor problems — a real concern in pregnancy and afterwards, when constipation is common.
Nothing to maintain
No power, no app, no refills and no subscription. An occasional wipe-down is the entire maintenance schedule.
The research
What the research shows.
Four studies do most of the work here. These are their reported figures, including the limitations the researchers note themselves.
51sversus 130s sitting
Twenty-eight healthy volunteers timed six bowel movements each in three positions. Satisfactory emptying averaged 51 seconds squatting, against 114s on a low seat and 130s on a standard one — and straining fell in every single volunteer.
Sikirov D. Dig Dis Sci 48:1201–1205, 2003 · read it126°versus 100° sitting
X-ray video plus pressure measurement, taken at the same time. The anorectal angle measured 126° squatting against 100° sitting normally. The more the hips bend, the straighter the canal — and the less push it needs.
Sakakibara R, et al. LUTS 2(1):16–21, 2010 · read it3.64×odds of finishing properly
Fifty-two adults, four weeks: two without a stool, two with. Using one raised the odds of complete evacuation (OR 3.64) and cut the odds of straining (OR 0.23). Take it away and visits got 1.25× longer again.
Modi RM, et al. J Clin Gastroenterol, 2019 · read it42studies reviewed, 2025
A formal review across Scopus, PubMed and Web of Science. Squatting postures may reduce strain and improve emptying — while sitting designs stay more comfortable and safer for older adults and anyone with limited mobility.
Sitting vs. squatting. BMC Public Health 25, 2025 · read itThe honest bit
That 2025 review is blunt about the evidence: small sample sizes and poorly controlled confounders “preclude definitive conclusions.” A footstool is cheap, reversible and low-risk, which is a good reason to try one — it isn't a reason to skip your doctor. Ongoing constipation, bleeding or any change in your habits needs a clinician, not furniture.
The range
Pick your height.
Under 5′10″, start with the 7″. Taller than that, or you want a deeper squat, take the 9″. All of them tuck around a standard toilet.

Support
Frequently asked questions.
7″ or 9″?
Height matters more than shoe size. Under about 5′10″, the 7″
usually gets your knees comfortably above your hips. Taller, longer-legged, or the 7″
doesn't feel like it's doing much — take the 9″. If a household can't agree, the Bamboo
Flip is both heights in one object.
Can't I just use a shoebox?
Honestly, for a week — yes, and we'd rather you tried it than didn't.
The geometry is the active ingredient, not the branding. What a proper stool adds is the
cut-out that lets it live tucked around the toilet base, a non-slip footprint where your
weight actually lands, and a surface you can clean. Boxes fail all three by about day ten.
Is any of this actually proven?
Partly, and we'd rather say so. The mechanism is well
documented — bending the hips widens the anorectal angle, measured on X-ray and with
pressure sensors. The outcomes (faster, easier, more complete) show up
consistently in small studies including a 2019 trial, but the 2025 review is explicit that
samples are small and confounders poorly controlled. So: solid mechanism, encouraging but
limited outcome data, and very little downside. Have a look at
the research and decide for yourself.
Will it help my haemorrhoids?
It may reduce one of the things that aggravates them — straining.
It isn't a treatment. Haemorrhoids that bleed, prolapse or hurt persistently should be
looked at, and rectal bleeding should never be self-diagnosed as haemorrhoids.
I'm pregnant or postpartum. Is it safe?
Toilet-posture support is routinely suggested by pelvic health
physiotherapists, and constipation is very common in pregnancy and after birth. That said,
pregnancy changes your balance and your pelvic floor, so please check with your midwife,
OB or pelvic floor PT first — especially after a caesarean or a significant tear.
Who shouldn't use one?
Anyone whose balance, hip range or knees make lifting the feet
unsteady — that includes many older adults, people with hip or knee replacements, and
anyone at risk of falls. The 2025 review specifically notes seated designs are safer and
more comfortable for those groups. If getting on and off the toilet is already an effort,
talk to an occupational therapist before adding a stool.
How do I clean it?
It's a bathroom object, so treat it like one. The polymer models take
any household bathroom cleaner or a diluted bleach wipe. Bamboo prefers a damp cloth with
mild soap and a dry-off — don't soak it or leave it standing in water.
