One cushion still hasn't expanded after a few days. What should I do?
Also asked as:One of the back cushions did not fully expandThe armrest hasn't inflated yet
Vacuum-packed foam comes out of its bag like a sail out of its sock. Most of it fills at once. Now and then one corner takes its time.
SaveThe quick answer
A foam cushion that hasn't fully expanded usually recovers if you take the cover off, shake, pull and pinch the foam, and give it a few more days. Most pieces rise within 24 to 48 hours of opening. If one section is still flat, dented or hard after several days, send photos: replacement foam ships with tracking and your cover moves onto it.

Reading the foam, day by day
| What you see | When | What to do |
|---|---|---|
| Soft, creased, still rising | First 24 to 48 hours | Leave it; most pieces fill out in a day or two |
| Half-risen, or puffed only at the edges | Day 2 or 3 | Cover off; shake, pull and pinch the foam, then refit |
| A back cushion filling slowly | A couple more days | Wait; one L-shaped backrest filled out on its own |
| Flat, dented, thin or hard while the rest has risen | After several days | Photos from several angles; replacement foam ships |
Key facts
- Most vacuum-packed pieces recover within about 24 hours; some need 36 to 48 hours after the bag is opened.
- Foam that won't expand is rare.
- Removing the cover and shaking, pulling and pinching the foam helps half-risen pieces.
- A section still flat, dented, thin or hard after several days is treated as faulty foam.
- Replacements have been sent after waits of 3 days, 5 days and about a week.
- Replacement foam ships as one piece with tracking, and your existing cover goes onto it.
- The workshop asks how many days the box sat before it was opened.

Leave your details and the workshop will call you to confirm measurements, fabric, foam and piping. No prices, dates or payment on this page: it is a request, not an order.
Working a slow foam cushion by hand
Unzip and slide the cover off
Work the foam bare, not through the fabric.
Shake, pull and pinch
Work the flat spots and the middle with both hands until the filling loosens.
Refit and wait
Put the cover back on and give it a few more days before you judge it.
One flat pad, one slow backrest
A buyer in the US unpacked a floor sofa and found every piece risen but one: a large pad, still flat and hard three days on. That's not settling. The workshop sent a replacement pad.
Another buyer in the US had a slow L-shaped backrest. A couple more days, and it filled out by itself. Same kind of box, two endings.
Why the workshop asks about the box
I treat a vacuum bag the way I treat a sail before weather: open it the day it lands. When a piece won't rise, the workshop asks how many days the box sat before you opened it, and wants photos from different angles. Faulty foam is rare, but when it happens a new foam piece, seat insert or back cushion ships with tracking, and you move your existing cover onto it.
The first 72 hours of a vacuum-packed cushion are worth reading before the box arrives, and the modular floor sofa pages show how the pieces fit together. So tell me, friend: how long did your box sit in the hall before you cut the tape?
Replacement foam for a cushion that never rose ships as one piece, and your existing cover goes onto the new foam, so the fabric you chose stays the fabric you have.

Buyer questions
- A common question
My floor sofa came vacuum-packed. How long until the cushions expand, and what if one stays flat?
The workshop's answerMost foam cushions get back to full shape within about 24 hours, though some pieces need 36 to 48 hours after the bag is opened. If one is still dented, thin or hard in places after a few days, the workshop treats it as damaged or wrong foam and sends new filling. You move your cover onto it.
- A common question
One cushion never fully expanded. What now?
The workshop's answerIt happens rarely. In past cases the workshop sent a new foam piece or back pillow and asked how many days the box sat before it was opened. One buyer gave the pieces 5 days to rise before writing in.
- A common question
How long should a compressed cushion take, and when should I ask for help?
The workshop's answerGive it a couple of days, then take the cover off and shake, pull and pinch the foam. If one section is still flat or hard after several days, send photos from different angles and note how many days the box sat before you opened it. Replacements have been sent after waits of 3 days, 5 days and about a week.
- A common question
I only see a cover in the box. Where's the foam?
The workshop's answerAlmost certainly inside it. Inserts are vacuum-compressed within their covers, so a cushion can look like a cover alone. Open it and the foam expands within a few days. Every order is photographed before shipping, and missing foam is investigated.
Questions buyers ask next
Should I open a vacuum-packed cushion as soon as it arrives?
Yes. Open it promptly and allow about 36 to 48 hours for the foam to expand. If a piece later needs replacing, the workshop asks how many days the box sat unopened, so note the day it arrived.
Do I need a new cover if the foam is replaced?
No. Replacement foam ships as a single piece with tracking, and you move your existing cover onto it. The cover you already have stays in use, so the color and fabric of the set don't change.
Is a cushion that only puffs up at the edges faulty?
Not necessarily. Pieces that stay half-risen or puff only at the edges often recover once the cover is off and the foam is shaken, pulled and pinched. If the middle is still flat after several days, send photos.
