Bay windows are the best seat in the house and the most awkward thing to furnish. They give you three sides of glass, a natural alcove and the pleasant sense of being tucked slightly away from the rest of the room. They also bring cold panes, odd angles, a radiator where you wanted a footstool, and a sill at exactly the wrong height. Get the seating and the light right, though, and the awkwardness disappears. What is left is the corner everyone drifts towards without quite knowing why.
Start with the space, not the shopping
Before you buy anything, spend ten minutes with a tape measure. You need four numbers: the width of the bay at its widest point, the depth from the glass to the narrowest part of the opening, the height of the sill, and the distance from the bay to the nearest doorway or well-walked route through the room.
Then look at what cannot move. Most bays have a radiator under the sill. Some have a built-in seat at a height that suited a child thirty years ago. Others have sockets in unhelpful places, or none at all.
A simple order of work saves money and returns:
- Measure the bay and photograph it from three angles in daylight.
- List the fixed obstacles: radiator, sockets, window handles, sloping ceiling.
- Decide where a person will actually sit, and which way they will face.
- Sort lighting, then seating, then textiles.
Most people work the other way round, buy a chair that suits the look rather than the alcove, and shuffle it around the room for a year.
Choose seating that suits the shape
A window seat or bench
A bench is the most space-efficient option and the most forgiving of odd angles, because it can be made to follow the shape of the bay. For sitting upright, a depth of 45 to 50 centimetres is enough. If you like to curl up with your legs tucked beside you, aim for 60 to 70. The pad should be firm rather than squashy: 7 to 10 centimetres of foam with a removable, washable cover will still feel supportive in three years' time. If you are having one made, ask for a lift-up lid with storage underneath. It is the cheapest extra storage you will ever add to a room.
An armchair or tub chair
In a deep bay, a compact armchair set slightly off-centre works well, angled towards the room rather than the glass so you are not staring at your own reflection after dark. Leave at least 45 centimetres of clearance on the side you walk past, and check the chair back does not rise above the sill line, or the window will feel blocked.
When the bay is shallow
Bays of 40 centimetres or less will not take a chair, so do not force it. Put a slim console or a narrow shelf in the bay for a lamp and a stack of books, then place the chair just outside the bay, turned inwards. You keep the light and the sense of enclosure without the squeeze.
Light the page, not the room
Reading light needs to fall on the page, not into the reader's eyes, and it needs to be adjustable. A floor lamp with a pivoting head, or a wall light on an articulated arm, does the job far better than a pendant in the middle of the ceiling.
Place the lamp beside the seat, roughly at shoulder height when you are sitting, slightly behind you so the light comes over your shoulder rather than across your face. Warm white bulbs, around 2700K, feel softer in the evening than cool white ones, and a dimmer is worth the small extra cost.
Sockets are the usual stumbling block. Where there is none within reach, rechargeable table lamps and battery picture lights have improved enormously and will run for weeks between charges. If you want a permanent socket installed, use a registered electrician rather than running a cable across a doorway.
A low lamp on the sill, turned down, adds depth once the curtains are drawn. Keep it clear of the glass so the light does not bounce back at you.
Cushions, throws and the art of actually lounging
The difference between a window seat that looks good and one you use is usually back support. Sitting at 90 degrees against a window reveal becomes uncomfortable within twenty minutes. A firm cushion or bolster behind the small of your back, angled so you recline very slightly, changes everything.
On a bench, three to five cushions is plenty. More than that and you are moving them every time you sit down. A combination that works:
- Two 45cm squares for the back corners, in a fabric with some texture.
- One rectangular or lumbar cushion in the middle for lower back support.
- One larger 55cm cushion or a bolster in a contrasting weave.
- A wool or cotton throw folded over one end, within reach on a cold evening.
Mix textures rather than patterns: linen against wool, velvet against cotton. Keep colours tonal so the bay reads as one calm area rather than a jumble. If the window takes direct sun for hours a day, rotate the cushions every few weeks so fading is even.
Handle draughts, heat and glare
Old bay windows are often single glazed and draughty, which is why so many end up unused. Lined curtains hung on the room side of the bay, or a thermal blind fitted close to the glass, cut down both draughts and heat loss. A long fabric draught excluder laid along the back of the seat stops cold air reaching your ankles.
If there is a radiator under the window, do not box it in. Leave a gap so warm air can rise in front of the glass, which also helps reduce condensation, and choose a slatted or open-fronted bench rather than a solid panel.
For glare, a sheer voile or a linen blind that can be dropped halfway is more useful than blackout fabric. You want to soften the light, not shut it out.
If you live in a listed building, a leasehold flat or a conservation area, check before you drill, replace windows or add external fittings. Your local authority conservation officer or freeholder can confirm what is permitted.
Pulling it together in an afternoon
Start with the seat: measure, then find the pad or chair that fits the space rather than the space you wish you had. Add one adjustable light and move it until the page is bright and your eyes are not. Then layer in three cushions and a throw, keeping the colour quiet and the texture varied.
Finish with something small and personal: a side table just wide enough for a mug, a basket for magazines, a rug running from the room into the bay to claim it as its own. Sit down with a book for twenty minutes. If your shoulders drop and you stay longer than you meant to, the nook is finished.
