Which foam is best for Indoor Seat Cushions?

Seat cushions should be soft and comfortable, and should give a little, but not too much for most users. For our traditional polyurethan foam, start with our medium V44 Everflex foam for cushions between 4 and 6 inches thick. For organic seat cushions, We offer two main types of foam for indoor seat cushions; our traditional polyurethane (free of harmful chemicals), and our organic latex foam. Starting with the traditional polyurethane, we recommend our Everflex foam for couch cushions that will be used most days, and our lower-cost Econoflex foam for occasional use couch cushions in guest rooms or seldom-used areas. Most customers will be happy with our medium-firm V44 Everflex foam for couch cushions between 4 and 6 inches. If your couch cushion is thinner, you might consider firmer V54, and if thicker than 6 inches we generally recommend our softer V34. For latex foam, we recommend medium N31 or medium-firm N36 for standard thickness cushions. You can also select cushions using memory foam as a top layer above firmer polyurethane foam. Contact our customer service team for help with ordering.

Should I order dacron (polyester) batting for my seat cushions?

First, look at your existing cushions to see how they were built, and try to replicate the same use of dacron batting. FoamOrder recommends dacron batting for all polyurethane seat cushions, traditionally with a book wrap. A Dacron bookwrap gives an upholstered seat cushion a full, comfortable, rounded look. Without dacron batting your new or replacement seat cushions will likely show wrinkles in the fabric. For extra padding around your seat cushion or an extra-full look, use a double-dacron book wrap, or wrap all sides. We recommend our organic cotton or organic wool batting with an organic cotton wrap for our high-end organic latex cushions, to maintain the organic composition as well as to provide premium padding with your seat cushions. We guarantee you’ll feel the difference. If you really don’t want any dacron batting around your seat cushion, then order the foam 1/4" to 1/2" thicker than the case to make sure it fills in as much as possible.

How thick should seat cushions be?

When ordering seat cushions we recommend you keep the thickness of your cushions the same as the original so that you can use the slipcovers from the original couch. With new seat cushions, choose a thickness that will work within the design of the couch, normally between 4–6 inches. More than that is usually unnecessary, and thinner than 4" may lead to heavier users “bottoming out” and hitting the support materials below the cushions of the couch. The top of a seat cushion should generally be between 18" and 20" from the floor. Any taller than this and shorter people won’t be able to rest their feet comfortably on the floor.

Custom Chair Cushion Features

A FoamOrder chair cushion isn't a one-size chair pad. It's built around your chair, one choice at a time. Open any step below to see what you control, from the foam core to how the cushion stays put on the seat.

Shape & Size

Rectangles · tapered seats · T-cushions · custom patterns

Pick the shape that matches your chair seat, then enter its exact width, depth, and thickness. Nothing is rounded to a stock size, so the cushion fills the seat edge to edge instead of sliding around.

Rectangles & squares — the go-to shape for accent chairs, side chairs, and most lounge and reading chairs.
Trapezoids — for seats that are wider at the front than the back, which is common on armchairs and slipper chairs.
T-cushions — straight or curved, for club chairs and armchairs where the seat cushion extends in front of the arms.
Seat & back sets — two-piece chair and lounge sets, cut so the seat and back cushions match in thickness and fabric.
Custom pattern — for wingbacks and other chairs with odd curves or notches. Choose "Pattern Shape," trace your old cushion, and send us the template.

In the configurator you'll also set the unit of measurement, whether it's a seat or back cushion, and the quantity. Not sure how to measure your chair? See our How to Measure for Foam Cushions guide.

Foam, Quality & Firmness

Polyurethane · organic latex · memory foam · firmness rated by ILD

Choose a foam based on how often the chair gets used. Density (lb/ft³) drives how long the cushion holds its shape, and firmness is rated by ILD (Indentation Load Deflection). The higher the ILD, the firmer the seat.

Traditional Indoor Foam

High-density polyurethane foam for chair cushions

Open-cell polyurethane, free of fire-retardant chemicals, in three quality tiers. EverFlex is our premium high-resilience line for a favorite reading chair that gets sat in every day. DuraFlex is the mid-tier, and EconoFlex is the value option for a guest-room or occasional chair.

Foam	Tier	Feel	Density (lb/ft³)	ILD
V24	EverFlex	Soft	2.6	24
V34	EverFlex	Medium	2.6	34
V44	EverFlex	Firm	2.8	44
V54	EverFlex	Extra-firm	2.9	54
D30	DuraFlex	Soft	2.2	30
D40	DuraFlex	Medium	2.2	40
D50	DuraFlex	Firm	2.2	50
C25	EconoFlex	Soft	1.8	25
C33	EconoFlex	Medium	1.8	33
C55	EconoFlex	Extra-firm	1.8	55

Match firmness to thickness. A medium-firm V44 suits most 4 to 6 inch armchair and club chair seat cushions. Go firmer with V54 for thin seat cushions so you don't feel the chair frame, and softer with V34 for thick, plush cushions. Back cushions usually feel best a step softer than the seat.

Organic Natural Latex

$Natural organic latex foam for chair cushions$

GOLS-certified organic latex made from rubber-tree sap. It's naturally breathable, antimicrobial, and biodegradable, at roughly 5.9 lb/ft³ density throughout, with a springy feel that rebounds quickly when you stand up.

Foam	Feel	ILD
N25	Softest	25
N28	Soft	28
N31	Medium	31
N36	Medium-firm	36
N45	Firmest	45

For a standard-thickness latex chair seat, medium N31 or medium-firm N36 is the most popular choice. See all organic latex cushions.

Memory Foam

Slow-contouring, body-hugging foam (5.3 lb/ft³, ILD 13). On its own it sinks too far for a chair seat, so it works best as a top layer over a firmer base. To build a layered cushion, call us, or order both pieces and ask us to glue them together in your order comments.

Wraps

Dacron · down · cotton · organic wool

A wrap goes around the foam to round its edges and fill out the cover, so the cushion looks upholstered rather than boxy. Dacron is standard and strongly recommended on every chair cushion. Without a wrap, the cover tends to look baggy and wrinkled.

Dacron Wrap: four configurations

Polyester batting wrapped around the foam. Choose where it wraps (book vs. all sides) and how much (single vs. double thickness). A double wrap gives an armchair or club chair cushion that full, crowned look you see on high-end furniture.

Book Wrap

Wrap All Sides

Double Dacron Book Wrap

Double Dacron All Sides

Other wrap options

Down Envelope (all foam types)

A self-fluffing down envelope gives a club chair or lounge chair that soft, sink-in feel, while the foam inside re-lofts the down every time you stand up.

Cotton batting wrap and zippered cotton case

Cotton Wrap & Cover (organic latex)

A 1-inch (25 mm) layer of 100% cotton batting, then a custom-sized, zippered 100% cotton case that slides easily into your fabric cover.

Organic Wool & Muslin Book Wrap (organic latex)

Keeps the build all-natural while hiding the pin-holes that can show through thin fabric and preventing a baggy, sloppy look.

Covers

5,000+ fabrics · foam only · cover only · supply your own (COM)

Top your chair cushion with a new fabric cover, or skip it. Our library spans 5,000+ fabrics from leading mills:

Brands — Robert Allen, Premier Prints, Sunbrella, Trivantage, Hemp, and our own FoamOrder line.

Narrow them down by:

Filter	Choices
Application	Indoor for living room and bedroom chairs (outdoor and nautical also available)
Fiber	Natural fibers, synthetic fibers, natural/synthetic blends, vinyl & coated textiles
Pattern	Textured solids, geometric, stripes & lines, floral & botanical, plaid & checks, abstract, ethnic & global, classical, animal & skin, nautical & marine, novelty
Color	The full spectrum, including aqua, beige, blue, brown, green, grey, ivory, orange, pink, purple, red, white, and yellow
Price	Three tiers, from value ($) to premium ($$$)

For a chair that gets daily use, or one that pets and kids climb on, a synthetic or coated fabric is easier to clean and holds up better than a delicate natural weave.

Three flexible paths if you don't need a full new cushion:

Foam only — keep your chair's existing cover and replace just the flattened foam inside.
Cover only — keep your foam and get a custom-sewn cushion cover to refresh the look.
Supply your own (COM) — send us a fabric you love, such as one that matches your sofa, and we'll sew the cover from it.

Finishing Touches

Welt cording · top stitching · chair ties · Velcro · zipper

This is where a custom chair cushion pulls ahead of a store-bought pad. Dial in the construction details:

Edge finish: Overlock

Overlocked inside fabric edges preventing unraveling

Overlocking sews and finishes the inside fabric edges so they can't fray or unravel. It's what keeps a chair cushion cover intact through years of daily sitting, zipping, and washing.

Edge style: Welt Cording or Top Stitching

Welt Cording

The tailored, piped edge you see on most armchairs and club chairs. Match it to the cover fabric for a seamless finish, or pick a contrasting fabric to make the edge pop.

Top Stitching

A clean, durable stitched edge that suits modern accent chairs and adds strength along the seams.

Attachment: Chair Ties or Velcro

Keep the cushion from sliding off the seat with chair ties (two strands per set, sewn from your cover fabric) or sewn-on Velcro straps. Order up to eight sets, and specify placement, spacing, and tie length. 10 inches (25 cm) is standard.

Adhesive Velcro on request. For chairs without spindles or posts to tie to, we can add adhesive Velcro strips to your custom cushion. Mention it in your order comments, or call customer service at (415) 503-9314.

Closure: Zipper Placement

Zipper placement diagram, across the width

The zipper is flapped and hidden. On most chair seat cushions it runs along the back edge, where it's out of sight against the chair back.

Option	How it works
Across a side	Runs along the width, depth, or back/bottom, centered on the longest edge of that side.
Around the middle	Wraps three sides at mid-thickness. Best for cube-shaped cushions over 10 inches thick, like ottoman or floor cushions.
Custom location	Describe exactly where you want it, or send a marked diagram.

Every one of these is yours to set, and every chair cushion is still cut to order in the U.S.

Custom Chair Cushion FAQs

What foam is best for chair cushions?

For most armchair and accent chair seat cushions between 4 and 6 inches thick, FoamOrder recommends medium-firm V44 EverFlex, a high-resilience polyurethane foam with a 2.8 lb/ft³ density and an ILD of 44. Choose firmer V54 for cushions thinner than 4 inches and softer V34 for cushions thicker than 6 inches. For a guest-room or occasional-use chair, EconoFlex is a lower-cost option. If you prefer natural materials, medium N31 or medium-firm N36 organic latex suits most chair seats. Memory foam works best as a top layer over a firmer base foam rather than as the whole cushion.

How thick should a chair seat cushion be?

A chair seat cushion should usually be 4 to 6 inches thick, or the same thickness as the original cushion so it fits the chair frame and any existing cover. Cushions thinner than 4 inches can let heavier users bottom out and feel the seat deck or springs underneath. For comfortable seating, the top of the cushion should sit about 18 to 20 inches above the floor, which lets most people rest their feet flat on the ground.

Should I add Dacron batting to my chair cushion?

Yes, FoamOrder recommends a Dacron polyester wrap on every polyurethane chair cushion because it rounds the foam's edges, fills out the cover, and keeps the fabric from wrinkling. A single book wrap suits most armchairs and accent chairs. A double Dacron wrap or an all-sides wrap gives club chairs and lounge chairs a fuller, crowned look. For organic latex cushions, choose organic cotton or organic wool batting to keep the cushion all-natural. If you skip the wrap, order the foam 1/4 to 1/2 inch thicker than the cover so it fills in completely.

How do I measure a chair for a replacement cushion?

To measure a chair for a replacement cushion, record the seat's width, depth, and cushion thickness in inches, and check whether the seat is wider at the front than the back. For a tapered seat, measure the front and back widths separately and choose the trapezoid shape. For a T-cushion that wraps in front of the arms, or a wingback seat with curves or notches, trace the old cushion on paper and send it as a custom pattern. If you're reusing a cover, measure the cover seam to seam, since old foam is usually compressed. FoamOrder's measuring guide walks through each step.

Can I replace just the foam and keep my chair cushion cover?

Yes, you can order foam only, cut to fit your existing chair cushion cover, which is a lower-cost way to fix a flattened seat. Measure the cover seam to seam, choose your foam and firmness, and add a Dacron wrap so the new foam fills the cover smoothly. If your foam is still in good shape and only the fabric is worn, FoamOrder can sew a custom cover on its own, from its fabric library or from your own material (COM).

How long does a custom chair cushion take?

Foam-only chair cushions typically ship in about 3 to 14 days, and cushions with custom-sewn covers take about 4 to 6 weeks because each cover is sewn to order. Every FoamOrder cushion is cut to your measurements in the United States. If you need cushions by a specific date, contact customer service before ordering.

How do I keep a chair cushion from sliding off the seat?

Add chair ties or Velcro straps when you order your custom chair cushion. Chair ties come in sets of two strands sewn from the cover fabric, with up to eight sets per cushion and a standard length of 10 inches. Sewn Velcro straps work on chairs with spindles or frame rails to wrap around. For upholstered or solid chairs with nothing to tie to, FoamOrder can add adhesive Velcro strips on request; mention it in your order comments or call (415) 503-9314.

Are FoamOrder's chair cushion foams free of harmful chemicals?

FoamOrder's indoor polyurethane foams are CertiPUR-US certified and made without added fire-retardant chemicals, and its organic latex is GOLS certified (Global Organic Latex Standard), made from the sap of rubber trees. CertiPUR-US certified foams are independently tested for low VOC emissions and made without ozone depleters, PBDE flame retardants, mercury, lead, formaldehyde, or regulated phthalates.
