Sitting out of bed is an intervention in its own right, not a watered-down version of walking. It’s available to patients who can’t yet stand or transfer on their own, and it breaks up the continuous bed rest that causes deconditioning. For most inpatients it’s the first thing that can happen on day one. Older inpatients spend a median of 83% of measured hospital time lying in bed (Brown, JAGS 2009), and most of them can walk – so the gap between what people are capable of and what actually happens is enormous.
Mobilisation usually gets discussed as though it were one activity. In practice it’s a ladder, and each rung has different requirements, different staffing implications and different effects on the body.
Treating it as one thing causes a very specific failure. A patient who can’t safely stand gets written down as “unable to mobilise”, and then nothing happens at all – when in fact they could have been sat out in a supportive chair for two hours with two staff and a hoist.
| Rung | What it involves | Typical prerequisites | Main effect on the body |
|---|---|---|---|
| In-bed positioning | Head of bed elevated, side lying, regular repositioning, in-bed exercises. | Nothing beyond nursing capacity and a pressure care plan. | Limits sustained loading. Very little effect on muscle preservation or orthostatic tolerance. |
| Sitting out of bed | Transfer to a chair, hoisted or assisted, then sitting supported for a planned period. | Cardiovascular stability, a safe transfer method, and a chair the patient can tolerate. | Breaks up recumbency, loads the trunk, improves lung volumes and swallowing position, helps circulation. |
| Standing practice | Sit-to-stand transfers, standing with support, building standing tolerance. | Sitting balance, some lower limb strength, and orthostatic tolerance. | Weight-bearing through the legs, and direct use of the antigravity muscles. |
| Walking | Stepping with or without an aid, building up distance. | Standing tolerance, balance, and enough staff or equipment to do it safely. | Full functional loading, endurance, and the closest match to normal daily activity. |
None of this makes walking less valuable. The point is that a patient sits on one rung today and might be a rung higher tomorrow, and that “not walking” is a very long way from “not mobilising”.
Sitting upright without full back support uses trunk and hip muscles that lying down doesn’t. It isn’t resistance training, but it is loading – and the alternative is ten days of unloading that costs a healthy older adult around 0.95kg of lean leg mass (Kortebein, JAMA 2007).
Sitting upright increases functional residual capacity and makes coughing more effective. For post-operative patients and anyone with a chest infection, time spent sitting up has a direct bearing on whether secretions get cleared.
Eating semi-recumbent in bed is harder and less safe than eating upright in a chair. Sitting out at mealtimes also lets people feed themselves, which protects both their intake and the muscle that intake supports.
The reflexes that hold your blood pressure up when you stand deteriorate quickly with bed rest. Graded time sitting upright is how you hang on to them, and it’s a prerequisite for any standing practice later.
Being out of bed changes what a patient sees and hears, supports the day and night cycle, and means more incidental contact with other people. Immobility and delirium reinforce each other, so interrupting one helps with the other.
Having visitors, talking to the person in the next bay, and being spoken to at eye level rather than looked down on all matter enormously to patients. This isn’t a soft extra – patient willingness is usually what decides whether a sit-out plan works.
Sitting balance is where standing practice starts. A patient who has spent a week flat can’t begin at sit-to-stand.
This is the question ward staff actually ask, and there is a usable answer – as long as it sits alongside individual assessment rather than replacing it.
For higher-risk patients, a common starting point in international seating guidance is to limit sitting to around two hours per session, then check skin and tolerance before deciding whether to carry on. NICE clinical guideline CG179 recommends repositioning at least every six hours for adults at risk of pressure ulcers, and at least every four hours for those at high risk. Plan sitting and lying repositioning together, as one schedule.
The two-hour figure comes from the seating recommendations in the international pressure ulcer guideline (EPUAP, NPIAP and PPPIA, 2019), which advises limiting time seated without pressure relief for people at risk. It’s a starting position for somebody who can’t reposition themselves, not a ceiling for everyone.
Three things are worth adding.
| Patient | Reasonable starting plan | What to reassess |
|---|---|---|
| Repositions independently, low pressure risk | Sit out for meals and visits, for as long as they are happy. No fixed ceiling needed. | Fatigue, and whether the chair supports a safe sit-to-stand. |
| Limited independent repositioning, at risk | Start at 20 to 30 minutes, build towards up to two hours per session, aim for two sessions a day. | Skin over the ischial tuberosities and sacrum, comfort, posture, and whether they are sliding forwards. |
| No independent repositioning, high risk | Shorter, more frequent sits. Plan chair and bed repositioning as one schedule, at least four-hourly overall. | Skin at every transfer, whether the pressure-redistributing cushion is actually in use, seat depth and back angle. |
| Cardiovascularly unstable or deteriorating | Hold off, and review daily rather than assuming the decision stands all week. | Whether the reason for holding off is still true today. |
Brown and colleagues (Journal of Hospital Medicine, 2007) asked older inpatients, their nurses and their doctors what stopped patients getting up. The answers were mostly not about medical instability.
Discomfort in the chair provided, particularly after the first twenty minutes
Treat the chair as part of the clinical plan, not as ward furniture
Pain, especially on transfer and on sustained sitting
Record sit-out tolerance and build it, rather than testing it once and giving up
Fatigue, and a sense that getting up costs more than it gives back
Time analgesia before a planned transfer, not after a refusal
Fear of falling, in patients and in the staff helping them
Stable seating with supportive arms and a safe sit-to-stand height reduces fear on both sides
Lines, catheters, drains and monitoring making transfers feel risky
A named daily sit-out target makes it somebody's job
No documented expectation that anybody would be sat out that day
Measuring sit-out rates makes the gap visible to people who can resource it
If discomfort is one of the documented reasons patients don’t get up, and sitting out is how you interrupt bed rest, then how tolerable the chair is becomes a clinical question rather than a facilities one.
Here’s where the evidence currently stops. We’re not aware of any randomised controlled trial showing that a specific ward chair, ours or anybody else’s, reduces deconditioning outcomes. What we have is:
That’s a sound basis for specifying seating properly, and we think a procurement officer is better served by knowing which part is evidence and which part is inference. The full requirement-by-requirement breakdown is on ward chair specification, and we’re working on closing the gap through quality improvement projects with NHS wards that measure sit-out rates and duration.
Looking for the right chair rather than the clinical background? Our honest comparison of hospital bedside chairs weighs up the options, including chairs we don’t make, and the HiBack bedside chair is the product we built around the sit-out problem specifically.
We’ve also published the full evidence review behind this page, covering the mobilisation ladder, the barriers literature, the seating evidence and a ward chair specification, with every source named and dated: Sitting Out of Bed: Evidence Review.
For patients who can’t reposition themselves, international seating guidance (EPUAP, NPIAP and PPPIA, 2019) suggests limiting sitting to around two hours per session before checking skin and tolerance. NICE CG179 recommends repositioning at least every six hours for adults at risk of pressure ulcers, and every four hours for those at high risk. Patients who shift their own weight are in a different category and don’t need a fixed ceiling. Build tolerance up from short sits rather than starting at two hours.
