The Exit Strategy: Sofa Shopping for Knees, Backs and Everyday Real Life

There’s a moment in every sofa showroom when the room goes quiet and you realise you’ve made a terrible mistake. You’ve sunk into something deep, soft and beautifully styled, and now you’re trying to get up without using your hands, making a noise like a punctured airbed. It’s not the sofa’s fault, exactly. It’s just that nobody asked the obvious question: can you actually get out of it?

For plenty of UK homes, that question matters more than whether the fabric matches the rug. A sofa is not a sculpture. It’s the place where you drink tea, fold laundry, watch the last twenty minutes of a film while pretending to be awake, and host the grandparents on a Sunday. If getting up from it requires a plan, a countdown and a nearby doorframe, it’s the wrong sofa — however good it looked online.

Start with the exit, not the entrance

Most sofa shopping begins with the sit. We flop down, wiggle about, pronounce it “comfy” and move on. But the more useful test happens on the way back up. In a showroom, sit for a good few minutes — not the polite ten seconds — then stand naturally. Don’t push off with your hands if you can avoid it. Notice whether your knees have to travel forward, whether your feet stay flat, and whether you feel tipped backwards like an egg in a spoon.

If you’re shopping for a household with mixed ages, bring the person who’ll use it most. A sofa that’s easy for a lanky teenager may be a trial for someone with arthritic knees. And if you’re buying for a parent or grandparent who insists they don’t need “special” furniture, look for support that doesn’t announce itself. The aim is a sofa that’s kind to bodies without looking like it was ordered from a clinic catalogue.

Seat height: the Goldilocks measurement

Seat height is the distance from the floor to the top of the seat cushion. In general, sofas that are easier to get out of sit higher — often somewhere around 45cm to 50cm — while low-slung models can be closer to 35cm or 40cm. That difference sounds small until you’re the one doing the standing.

A simple check: sit with your feet flat on the floor. Your knees should be roughly level with your hips, or slightly lower. If your knees are up around your ears, the seat is too low. If your feet dangle, it’s too high. For anyone with back or knee trouble, a slightly firmer seat that doesn’t swallow you is usually kinder than a deep, squishy one.

Measure your current sofa at home, too. Take the height from floor to cushion, and the depth from front edge to backrest. Then compare those numbers with the showroom model. If your current sofa is a daily struggle, you’ve got a useful baseline: whatever it measures, aim for something a little higher and a little less deep.

Firmness is not the enemy

There’s a British tendency to equate “good sofa” with “soft enough to lose a remote control in”. But a seat that’s too soft gives you nothing to push against when you stand. It also tends to make you slide forward into a collapsed position, which is nobody’s idea of support.

A good seat cushion should give slightly under your weight and then push back. In the showroom, press down on the cushion with your hand, then sit near the front edge and see whether you feel supported rather than stranded. Foam and foam-and-fibre mixes tend to hold their shape better than pure fibre, though the latter can feel softer. If the sofa has removable cushions, ask whether they can be rotated or plumped. A little maintenance is fine; a daily wrestling match is not.

Arms, legs and the small details that help

Arm shape is quietly important. Low, narrow arms may look sleek, but they give you nothing to steady yourself with. A gently padded arm at a sensible height can be a real help when standing, and it doesn’t have to look fussy. Straight arms with a bit of width are often more practical than curvy scroll arms that force you to lean awkwardly.

Legs matter too. A sofa on low feet or a solid plinth sits closer to the floor, which can make standing harder. Raised legs create a bit of visual lightness and make the whole thing easier to get up from. They also help if you need to vacuum underneath, which is a small mercy in a house with pets or crumbs.

And don’t ignore the room. A high-backed, supportive sofa can feel wonderful but may block light from a bay window or crowd a narrow through lounge. Check the measurements against your actual layout, not the fantasy version of your living room. Leave enough space to walk past, and think about where you’ll put a side table or a lamp. A sofa that’s easy to get out of is no use if you have to climb over a coffee table to do it.

The at-home version of the test

If you’re buying online, you can still do a rough version of the exit test. Measure your current seat height and depth, then compare them with the product dimensions. Read the firmness description carefully — “medium-firm” is usually a safer bet than “super soft” for everyday comfort. Check the return policy before you order, and keep the packaging until you’re sure.

When the sofa arrives, sit on it properly for a week before you decide. Use it as you normally would: with a cup of tea, a laptop, a plate of toast. Notice whether you’re shuffling to the edge before standing, or avoiding it because it’s a faff to get out of. Those small annoyances add up.

The best sofa isn’t the deepest, the softest or the most photogenic. It’s the one that lets you enjoy sitting down because you know you can get up again. That’s not clinical. That’s just good furniture.
