An hour into a showroom visit, three chairs feel comfortable, and one feels correct. The difference is almost never the leather or the base. It is usually an inch of seat depth, and an inch decides whether your lower back is supported for the next twenty years or quietly working the whole time.
That inch is what Stressless recliner sizes are actually about. Mission Motif has been the authorized Stressless by Ekornes dealer in Atlanta for over 20 years, and the design team spends more time on this one measurement than on any other part of the order.
Height, leg length, and shoulder width each pull the decision in a different direction, which is why the model name tells you so little on its own. What follows walks the fitting the way it actually goes: what your body is telling you, what separates the three sizes, how the Plus system changes the lumbar and headrest question, and how much floor the chair needs at full recline. Bring a tape measure to the second half.
Assess Your Body Fit Before Comparing Sizes
Fit begins with your body measurements, not the chair's model name. Seat depth, back height, and headrest position have to line up with your leg length, spine, and shoulders, and those four dimensions rarely scale together.
A personalized fit means your feet rest flat, your lower back meets the lumbar curve, and your head is supported without pushing forward. Furniture industry seating guidelines put a comfortable seat height so the knee sits near a 90-degree angle. A recliner follows the same logic, with cushion compression factored in.
Why Height and Build Are Starting Points, Not Final Answers
Overall height gives you a rough starting size, but leg length drives seat depth more than total height does. Two people who both stand 5 feet 10 inches can need different sizes if one carries that height in the torso and the other in the legs.
Body build matters for seat width and arm spacing as well. Broader shoulders need a taller back and a wider seat pan to keep the arms relaxed at your sides.
Treat height as the first filter, then verify with the three checks below.
Check Seat Depth, Back Height, and Shoulder Placement
Sit all the way back before you judge anything. Correct seat depth leaves roughly two to three fingers of clearance between the seat's front edge and the back of your knees.
Back height should support your shoulder blades without the top edge pressing into your neck. If your shoulders rise above the back cushion, move up a size.
-
Seat depth too long: you slide forward, and your lower back loses contact with the lumbar support
-
Seat depth too short: thighs hang unsupported, and pressure builds behind the knees
-
Back too low: shoulders float above the cushion,n and the upper spine works to stay upright
-
Back too tall: the headrest pushes your head forward instead of cradling it
Test Lumbar Support and Headrest Position When Reclining
Lumbar support only proves itself in motion. Recline fully, then sit upright again, and feel whether the lower back cushion stays in contact through the whole range.
The same test applies to solid wood seating. A Morris chair design built with mortise-and-tenon joinery holds its back angle through fixed notches, so you feel the support change in discrete steps. A Stressless mechanism moves continuously, which makes the reclined position the one worth testing longest.
How the Plus System Adjusts Lumbar Support and the Headrest
The Plus system is what separates a Stressless recliner from a chair that simply tips backward. It ties the headrest and the lumbar support to the back angle, so as you recline, the lower back cushion follows your spine and the headrest changes angle to keep your head supported rather than pushed forward.
That changes what you are testing during a fitting. On a fixed-back chair, you find one comfortable position and hope it holds; here you are checking whether support tracks you through the whole range, from upright reading to the sleep position, which is set with a simple hand movement.
Size still decides the starting point. The Plus system refines lumbar and head position within a size. It cannot add seat depth or widen a seat pan, so it will not rescue a chair that is a full size off.
Once your body dimensions point to a size range, the next question is what actually separates one size from the next.
How Stressless Recliner Sizes Differ: Small, Medium, and Large
Stressless recliners scale in three dimensions at once: seat width, seat depth, and back height all grow from small to medium to large. The frame, the internal springs, and the metal arm support bars change with the size, so a small chair is a distinct build rather than a trimmed-down large.
Because the build scales rather than the cushion simply getting bigger, a chair that fits you holds its shape better over years of daily use than one you sized up or down into.
Read the height ranges below as fitting guidance, not as published specifications. Stressless notes that most of its recliners, not all of them, come in small, medium, and large, and the actual dimensions behind each label differ from one series to the next.
Who Typically Fits a Small Recliner
A small recliner suits shorter frames and lighter builds, where a deeper seat would leave the feet dangling or the lower back unsupported. Adults under roughly 5 feet 5 inches often find the small recliner holds the lumbar curve where it belongs, though that is a fitting rule of thumb rather than a specification.
Smaller chairs also read better in tight rooms. A study, a reading nook, or a bedroom corner beside a Mission spindle bed usually calls for a compact seat that keeps sightlines open.
When a Medium Recliner Is the Better Starting Point
The medium recliner covers the widest band of adult bodies, roughly 5 feet 5 inches to 5 feet 11 inches, which is why showrooms keep more mediums on the floor. Start here if you are unsure, then step up or down after sitting.
Medium sizes also pair well with standard-scale living room furniture. Beside an eight-foot Mission style sofa, a medium recliner holds visual balance without crowding the arm.
When a Large Recliner Provides Better Support
A large recliner serves taller adults and broader builds, generally 6 feet and up, by adding seat depth, back height, and shoulder room together. Taller sitters who feel their shoulders clear the back cushion on a medium belong in a large.
Larger chairs occupy noticeably more floor area when reclined. Plan the room around that footprint before committing.
Why Sizes Vary Among Recliner Models
Not every model offers all three sizes. Each design has its own frame geometry, cushion profile, and base diameter, so a medium in one series does not measure identically to a medium in another.
This is why a size you sat in years ago, or one a friend recommends, is only a starting point. Confirm the size against the specific model you are ordering rather than against the letter on the label.
How to Identify the Size of an Existing Chair
The metal arm support bars under the arms carry a stamped size marking on many Stressless chairs. Tip the chair gently and look at the underside of the bar where it meets the frame.
-
S, M, or L stamp on the metal arm support bar, visible from underneath
-
Seat width measured across the cushion at its widest point, compared against published recliner measurements
-
Back height from the seat cushion to the top of the headrest, taken with the chair upright
-
Base diameter, which grows with each size step
Knowing your size settles the chair. The room still has to hold it at full extension.
Plan the Room for a Comfortable Recline
A Stressless recliner needs clearance at full recline, and the chair-and-ottoman pairing extends farther than most people estimate. Measure the reclined footprint, not the upright silhouette, before you decide where the chair lives.
Wall clearance behind the chair also matters. Many Stressless models recline within a modest rear allowance, but the exact figure changes by model and base, so confirm it for the chair you choose.
Measure the Full Chair-and-Ottoman Footprint
A free-standing ottoman sits several inches away from the chair front, and that gap counts as usable floor space. Measure from the back of the chair to the far edge of the ottoman with your legs up.
Mark the outline on the floor with painter's tape. This shows you what the reclined footprint takes from the room far better than a number on a spec sheet.
Allow Clearance for Walking Paths and Nearby Furniture
Leave at least 30 to 36 inches for a main walking path around the reclined position. Anything narrower turns into a daily detour once the ottoman is in use.
Side tables need their own clearance. A lamp table beside a recliner should sit close enough to reach without leaning, roughly at arm height, and far enough that the reclining arm never contacts it.
Use Sofa Measurements to Maintain Proper Visual Scale
Compare sofa measurements to the recliner before finalizing size. A recliner whose back height falls within a few inches of the sofa back keeps the seating group visually level.
Scale reads through material too. A wool rug such as the hand-knotted Mission rug can anchor a seating group and define where the recliner's footprint belongs, provided the front legs of every piece land on the pile.
Measure Doorways, Hallways, and Delivery Turns
Measure the narrowest point on the delivery path, including door frames, stair turns, and hallway corners. Diagonal clearance through a turn usually limits delivery more than the doorway width does.
Note ceiling height on stairwells as well. Once the room is measured and the size is settled, the choices that remain are visual ones.
Choose Features and Finishes After Finding the Right Size
Base wood, leather grade, and fabric texture all read differently at different chair scales, which is why these decisions come after sizing. A dark base under a large chair anchors it; the same base under a small chair can look heavy.
Stressless by Ekornes builds these chairs to order, so treat the finish selection as a specification exercise rather than a shelf pick.
How the Glide System Responds to Your Movement
The glide system uses body weight and a two-position wheel to adjust the balance between back and seat, so the chair follows you as you shift. Set the wheel once for your weight, then leave it.
That responsiveness is the ergonomic argument for the chair. Verify it while sitting in the size you selected, since the glide tension is calibrated per size.
Select a Base That Complements the Room
Wood base finishes should relate to the hardwood already in the room. Consider three anchors when choosing:
-
Existing furniture finish, such as the warm amber tone common on quartersawn white oak Mission pieces
-
Floor color and species, since a base that matches the floor exactly can disappear visually
-
Trim and millwork stain, which sets the room's baseline warmth
Wood behaves consistently, which is why quartersawn oak furniture remains the reference point for Arts and Crafts interiors. Its ray fleck reads as figure rather than pattern, so it sits calmly beside leather.
Coordinate Leather or Fabric With the Chair's Scale
Large chairs carry a broad surface, so a heavily textured fabric or a strongly grained leather shows more of itself there than on a small chair. Fine-grained leathers keep a large chair from visually dominating a room.
Small and medium chairs handle bolder color better because the surface area is limited. Bring a cushion or a swatch from the room when you compare.
Understand Custom-Order Timing and Availability
These chairs are ordered to your size, base, and covering, and custom furniture in this category runs on a 14 to 16 week lead time. Plan accordingly if the room has a completion date.
Solid hardwood companion pieces follow the same rhythm, cut and finished only after the order is placed. That is the trade-off behind a made-to-order piece: you wait, and in return, nothing about the chair is a compromise you inherited from a warehouse.
A Properly Fitted Recliner Is Easier to Enjoy for Years
The right size is the one where your feet rest flat, your lower back stays in contact through the full recline, and the headrest meets your head without pushing it forward. Everything after that, base wood, leather grade, fabric texture, refines a chair that already fits.
That principle carries across the room. Furniture built with solid wood joinery earns its reputation for the same reason a well-fitted recliner does: the fit was decided precisely, before anything was assembled. Furniture chosen that way tends to stay in service instead of being replaced.

Frequently Asked Questions
How Do I Know What Size Stressless Chair to Get?
Sit in a medium first, then adjust up or down based on seat depth, back height, and headrest position. Your lower back should meet the lumbar curve while two to three fingers fit behind your knees. Height gives a starting point, but leg length and shoulder width decide the final size.
What Size Recliner Do I Need for My Height?
As a general starting range, adults under about 5 feet 5 inches often fit a small; 5 feet 5 inches to 5 feet 11 inches suits a medium, and 6 feet and above points to a large. Build and leg length shift those ranges, so confirm by sitting.
What Is the Difference Between a Medium and Large Stressless Recliner?
A large recliner adds seat width, seat depth, and back height compared with a medium, along with a wider base. The extra back height is what taller sitters notice most, since it keeps the shoulders supported instead of clearing the cushion.
How Much Space Do I Need for a Stressless Recliner and Ottoman?
Measure the full reclined footprint from the back of the chair to the far edge of the ottoman, then add 30 to 36 inches for a walking path. Tape the outline on the floor to see the real footprint before ordering.
Can I Use the Metal Arm Support Bars to Identify My Stressless Chair Size?
Yes. Many Stressless chairs carry a stamped S, M, or L marking on the metal arm support bars underneath the arms. If the stamp is worn, measure seat width and back height and compare those recliner measurements against the model's published dimensions.
Do All Stressless Recliner Models Come in Small, Medium, and Large Sizes?
No. Size availability varies by model, and some designs offer only one or two sizes. Frame geometry and cushion profile also differ between series, so a medium in one collection does not measure identically to a medium in another.
