# Can you make a washable zippered cover for a crash pad or a crib-mattress play mat?

*A play mat lives on the floor and gets loved hard. Its cover should come off as easily as the afternoon does.*

Also asked as: Cover for a crib mattress floor play mat?; Fully zippered box-style cover?

> **The quick answer:** Yes: fully zippered, machine-washable box-style covers are made for crib mattresses used as floor play mats and for sensory crash pads. A 61 x 61 x 10 in (155 x 155 x 25 cm) crash pad cover gets a long zipper for easy removal. Order through the cover listing and write the exact size and fabric code in the personalization box.

## Why a thick pad wants a long zipper

A [crash pad](https://cushionguide.com/glossary/#crash-pad) 10 in (25 cm) thick and 61 in (155 cm) square is a lot of foam to coax out of a sleeve. So its cover gets a long zipper: the bigger the opening, the easier the pad slides free on laundry day and goes back in square. The mini crib mattress, at 3 in (7.5 cm), gets a fully zippered box cover for the same reason.

For color, my friends, look at the floor the mat will live on. Oatmeal and warm beige are on the linen chart, and they sit calmly on oak or a pale rug. What color is the floor under your mat?

## Ordering a cover for a pad you already own

1. **Measure the pad**: Length, width and thickness of the mattress or crash pad itself, in inches.
2. **Pick the size range**: On the cover listing, choose the range your pad falls into.
3. **Write the exact size and code**: Put the exact dimensions and your fabric code in the personalization box.
4. **Decide on piping**: Say yes or no, and if yes, give the piping code.

> **Tailor's margin:** A crash pad cover at 61 x 61 x 10 in gets a long zipper: the longer the opening, the easier thick foam slides out for washing.

> Oatmeal and warm beige play mat covers come off the linen chart, soft colors that sit calmly on an oak floor or a pale rug.

## Buyer questions

**A common question:** Could you sew a fully zippered, washable box cover for a mini crib mattress I use as a floor play mat?

**The workshop's answer:** Yes, a removable, washable, fully zippered box-style cover for a 37.75 x 23.75 x 3 in (96 x 60 x 7.5 cm) mattress is no problem. Order through the cover listing: select the size range and write the exact size and fabric code in the personalization box.

**A common question:** Can you make a big removable cover for a sensory crash pad that I can machine wash?

**The workshop's answer:** Yes, a 61 x 61 x 10 in (155 x 155 x 25 cm) machine-washable cover with a long zipper was quoted. The workshop needs a fabric code (the linen chart for oatmeal or warm beige) and whether you want piping, and in which code.

**A common question:** What measurements do you need to cover foam I already have?

**The workshop's answer:** The exact length, width and thickness of each insert. Choose the closest size range, write the sizes and fabric code in the personalization box, and place one order per size; odd thicknesses such as 5.5 in (14 cm) are fine.

**A common question:** The zipper on my cover is stuck. What should I do?

**The workshop's answer:** Usually fabric is caught in the teeth. Free it, run the slider fully back and forward, and on snug covers press the foam in while zipping. If it still fails, send the workshop photos or a short video of the zipper.

## Questions buyers ask next

### Can I add piping to a play mat cover?

Yes, piping is optional. Tell the workshop whether you want it and give its fabric code. Leaving it off gives a softer, simpler edge on a mat that children roll across all day.

### Which colors suit a nursery play mat cover?

Oatmeal and warm beige tones from the linen chart were suggested for a crash pad cover. They're calm, easy shades on a light floor; ask for close-ups of two or three codes before you choose.

### Can a tufted floor cushion get a zippered cover instead?

No. Tufted cushions are hand-stitched closed with buttons through the filling, so they can't be unzipped. For a washable floor piece, choose a plain foam cushion or a box cover over your own mattress.
