A chaise is the part that trips people up. A straight sofa is easy to picture covered — one piece, four panels, done. But the moment a sofa grows a chaise, a corner unit, or a long sectional run, the question changes from "which cover" to "how many, in what order, and which way around." That uncertainty is the reason corner and chaise sofas feel harder to cover than they actually are.
They are not harder. They just need a different way of thinking — section by section, rather than sofa as one object. Once you stop looking at a sectional as a single thing to wrap and start seeing it as a set of individual units, each with its own cover, the whole job becomes a series of simple, familiar steps. This guide shows you how to count your pieces, read the orientation of a chaise, and fit the chaise section so it sits as cleanly as the rest of the sofa.
First, see your sofa as sections, not as one piece
The single mental shift that makes everything easier: a chaise or sectional sofa is covered per section, not with one giant cover stretched over the whole shape. There is no single cover that wraps an L in one go — and that is good news, because individual section covers fit far better, wash more easily, and let you replace just one piece if it ever needs it.
So before anything else, walk around the sofa and identify its sections. Most chaise and sectional sofas are made of some combination of these:
- Seat sections — the standard upholstered seats, the same as a straight sofa.
- A corner unit — the square section where two runs meet at a right angle.
- A chaise — the extended seat with no arm at the far end, the part you stretch your legs along.
- An armless or middle unit — on modular sofas, a seat with no arm on one or both sides.
Each of these is a section, and each gets its own cover. Count them now and you already know roughly how many covers you need. A precise count comes next.
Counting your pieces
Counting is where most mistakes happen, so do it deliberately. Walk the sofa from one end to the other and count every distinct seating unit, including the chaise and any corner.
Here is a worked example. A common L-shape sofa has a three-seat run, a corner, and a chaise extending off it. Counting the units: the three-seat run is one section, the corner is one section, the chaise is one section — three covers in total. A larger U-shape with two arm-runs and a chaise between them might count as four. A modular run of separate seats is counted one cover per module.
The reliable rule: count the upholstered units, not the cushions. Cushions are removable and can mislead you — a three-seat section has three seat cushions but is still one section needing one cover. Count the frame units. If you are unsure where one section ends and the next begins, look at the underside or the seams; the construction usually reveals the divisions.
For the full shape-by-shape breakdown — L-shape, U-shape, modular, and how each is counted — our corner and sectional sofa covers buying guide goes deeper. This piece focuses on the part that confuses people most: the chaise itself.
Reading the orientation — left-hand vs right-hand
The chaise has a direction, and getting it wrong is the most common ordering mistake on a sectional. A chaise sits on the left or the right, and the cover (or the section) is described that way — so you need to know which yours is before you buy.
Here is the simple way to read it: stand and face the sofa as if you are about to sit on it. Look at which side the chaise extends to from that position. If the chaise is on your left, it is a left-hand chaise. If it is on your right, it is a right-hand chaise. That is the whole test — face the sofa, note the side, done.
The reason it matters: a chaise section is not symmetrical. It has an arm on one side and an open end on the other, so a cover cut for a right-hand chaise will not sit correctly on a left-hand one. The panels, the arm shaping, and the open end all need to match the actual orientation. Reading it from the facing position, the way you naturally sit down, removes the confusion that comes from describing it "from the sofa's point of view."
Fitting the chaise section
Once you have the right cover for the right orientation, fitting the chaise follows the same drape-tuck-settle method as any seat — with two small differences because of the open end and the longer seat.
- Drape the cover over the chaise so its seams roughly line up with the chaise's own seams — the back, the seat, and the single arm.
- Square the open end first. The chaise's defining feature is the end with no arm. Pull the cover snug over that open end and smooth it down so it wraps cleanly, because this is the edge most on show and the one most likely to look slack if ignored.
- Tuck the back-to-seat seam deep into the gap along the full length of the chaise. The chaise seat is longer than a standard seat, so work along the whole run, not just the middle.
- Tuck the arm seam on the side that has an arm, exactly as you would on a standard seat.
- Smooth the long seat panel from the back forward and from the arm toward the open end, pushing any slack out to the seams and the open edge, where it tucks or wraps away.
The longer seat is the only real difference, and the fix is simply to work along its whole length rather than treating it like a short seat. A chaise fitted this way sits as cleanly as the rest of the sofa.
Where the chaise meets the next section
The join between the chaise and the seat section beside it is the spot that can gap if rushed. The two covers meet at a seam, and the goal is for that meeting to look continuous rather than like two separate covers butted together.
Fit the seat section first, then the chaise, and at the join push the edges of both covers down into the gap between the two frame units. The fabric of each cover tucks into the same crease, so the two disappear into one another and the eye reads an unbroken surface. A foam rod pressed into that gap on top of the tucked fabric holds the join closed if the sofa is slick or sees heavy use. Done well, you cannot tell where one cover ends and the next begins.
Getting the measurements right for a chaise
A chaise is longer than a standard seat, so its measurements are the ones most often guessed wrong. Measure the chaise as its own unit: the width across the seat, the depth from the back all the way to the open end (this is the long measurement, and the one people underestimate), and the height. Note which side the arm is on while you are there — that confirms the orientation.
The full measuring method, including how to handle the longer chaise depth and the arm shape, is in how to measure your sofa. Take those numbers to the stretch covers for sofas and corner sofas range, match the chaise section to its size and orientation, and the section that intimidated you becomes the easiest part of the order.
The thinking behind it
A chaise or sectional sofa is not a single object to wrap — it is a set of sections, each with its own cover, fitted one at a time. Count the units, read the chaise's orientation from where you sit, fit the chaise along its full length, and close the joins into the gaps. Every step is the familiar drape-tuck-settle method, just repeated per section.
That section-by-section approach is what makes covering a large, non-standard sofa not only possible but genuinely satisfying — you refresh a complicated, much-loved piece without replacing any of it. Keep what you love, change how it feels, one section at a time. Browse the stretch sofa covers range, or read more about the idea behind it on our story.
FAQ
Q1: Can one cover fit a whole sectional with a chaise? A1: No — chaise and sectional sofas are covered per section, not with a single cover. Each seat run, corner unit, and chaise gets its own cover. Individual section covers fit far better, wash more easily, and let you replace just one piece if needed.
Q2: How do I know if I have a left-hand or right-hand chaise? A2: Stand and face the sofa as if you're about to sit on it. If the chaise extends to your left, it's a left-hand chaise; to your right, it's a right-hand chaise. The chaise isn't symmetrical, so the cover must match the orientation.
Q3: How many covers do I need for an L-shape sofa with a chaise? A3: Count the upholstered units. A typical L-shape with a three-seat run, a corner, and a chaise needs three covers — one per section. Count the frame units, not the cushions.
Q4: How do I fit a cover on the open end of a chaise? A4: Square and smooth the open end first, pulling the cover snug over it so it wraps cleanly, then tuck the back and arm seams. The open end is the most visible edge, so fitting it first keeps it from looking slack.
Q5: How do I stop a gap where the chaise meets the next section? A5: Fit the seat section first, then the chaise, and push the edges of both covers into the gap between the two frame units so they tuck into the same crease. A foam rod in that gap holds the join closed on a slick or busy sofa.
