Frequently Asked Questions About Mattress-Wrapping
The dimensions of my crib mattress are different from the
BabeSafe cover sizes. How do I calculate which cover size to
use on my mattress?
1. Measure the mattress around its entire width (the girth).
2. Match the mattress girth with the BabeSafe cover girths
Size A (bassinet)
Size C girth 47" (cosleeper or playpen)
Size E girth 52" (US standard size)
Size F girth 52" (US large size)
Size P girth 60" (portable crib)
3. Then match the mattress length with the BabeSafe cover mattress
lengths set out below:
Size A (bassinet)
Size C width 23" (cosleeper or playpen)
Size E width 26" (US standard size)
Size F width 26" (US large size)
Size P width 45" (portable crib)
4. Finally, match the mattress height to the following:
Size A height (bassinet)
Size C height 5" (cosleeper or playpen)
Size E height 5" (US standard size)
Size F height 7" (US large size)
Size P height 2" (portable crib)
5. Note that in the case of some mattresses, even though the girth may fit
(for example) a Size C cover, the mattress length will mean that Size E
or Size F needs to be used.
What bedding do I use on top of the BabeSafe-wrapped
1. On top of the wrapped mattress place a pure cotton blanket.
2. On top of the pure cotton blanket, place a pure cotton lower sheet
and a pure cotton upper sheet. (The baby sleeps between these sheets.)
3. On top of the upper sheet, place pure cotton or pure wool
4. Do not use any of the following items on a BabeSafe-wrapped
Any form of mattress pad
Any blanket which contains polyester
Any blanket which contains acrylic
Sheepskin or sheepfleece underlay
Sleeping bag or "clothing bag"
Duvet or quilt
Pillows or cushions
5. Do not use any bedding or clothing item which is in the form of a bag.
Can a BabeSafe cover on the crib mattress cause my baby to
No. As a matter of thermodynamics, the layer of polythene on a
BabeSafe-wrapped mattress is so thin in relation to the thickness of the
mattress that it has no measurable effect on the rate of heat transfer from
the baby to the mattress itself. Put another way, the cover does not
result in overheating.
Can a BabeSafe cover on the crib mattress cause my baby to
No. The plastic used in BabeSafe covers is polythene with a nominal
thickness of 125 microns. It is not physically possible for suffocation to
occur on this plastic. This plastic is so thick and strong that an adult
cannot tear it.
Can the plastic used in a BabeSafe cover result in
"outgassing" which could affect my baby?
No. BabeSafe covers are made from polythene which is strictly specified
in terms of chemical formulation and physical specifications. The
BabeSafe cover prevents any gases generated in a mattress from
reaching the baby, and the cover is itself incapable of any toxic gas
Do I need to air the mattress before enclosing it in the
If the mattress is new, it does not need to be aired before being enclosed
the BabeSafe cover. If the mattress has been previously used, air it for a
couple of days (preferably in sunshine) before enclosing it in the
Do I need to air the mattress after it has been sealed inside the
No. After the BabeSafe cover has been sealed, airing of the mattress is
achieved by means of the ventilation hole/s on the underside of the cover.
I don't have a cotton blanket to use immediately top of the
BabeSafe-wrapped mattress. Can I use something else
Yes. You can use:
A pure cotton flat blanket, or
A pure cotton sheet (folded into layers, if you wish), or
Cotton diapers sewn together, or
A pure cotton bath towel
Important: Do not use a cotton mattress pad.
Can I use bumper pads in the baby's crib ?
Yes. Bumper pads can be placed across the head of the crib and
part-way down the crib sides.
Are BabeSafe covers manufactured in sizes to fit adult-sized
No. BabeSafe covers are manufactured in five sizes for infant-sized
mattresses: one size for bassinets and a range of sizes for cribs and
portable cribs. For size details, click on the sidebar heading Product
My crib mattress is somewhat smaller than the BabeSafe cover.
What should I do about the excess plastic?
1. Do not cut the BabeSafe cover to fit the mattress.
2. Place the mattress inside the cover so that the printed side of the cover
is on the underside of the mattress.
3. Position the mattress centrally inside the cover.
4. Keeping the mattress in this centered position, seal the adhesive seal at
one end of the BabeSafe cover.
5. Make the cover firm and smooth around the mattress, and then fold the
excess plastic to the underside of the mattress.
6. Tape down the excess plastic with strong adhesive packaging tape,
taking care not to cover the ventilation hole/s on the underside of the
7. Place the wrapped mattress in the crib with the ventilation hole/s facing
the base of the crib .
8. Make up the crib following the bedding instructions for a
BabeSafe-wrapped mattress (see above).
My crib has a solid base and the ventilation holes on the
underside of the BabeSafe cover are obstructed. Do I need
to do anything about this?
Yes. Raise the BabeSafe-wrapped mattress slightly by placing a longish
thin item across the crib base. For this purpose use a thin piece of wood
(approximately pencil thickness) or a piece of thick string or thin rope.
The item which you use to raise the mattress must not be capable of
puncturing the BabeSafe cover. Place the item across the crib base so
that the mattress is elevated slightly where the ventilation hole/s meet the crib base. Then tape the item into position using strong wide adhesive
Raising the wrapped mattress slightly above the crib base will permit
ventilation of the mattress and will have no effect on the baby's sleeping
My crib mattress came manufactured with an integral plastic
cover as part of the mattress. How do I wrap this mattress in a
1. If the integral plastic cover on the mattress is removable (e.g., has a
zipper), remove the cover from the mattress before enclosing the mattress
inside the BabeSafe cover. Do not put the integral plastic cover back
onto the BabeSafe-wrapped mattress.
2. If the integral plastic cover is not removable and covers only part of the
mattress, place the mattress inside the BabeSafe cover so that the
integral cover faces upwards and the cloth-covered part of the mattress
faces the printed underside of the BabeSafe cover.
3. If the integral plastic cover is not removable and covers all of the
mattress, place the mattress inside the BabeSafe cover; and after the
BabeSafe cover has been sealed around the mattress, cut hole/s
through the integral cover corresponding with the placement of the
hole/s on the underside of the BabeSafe cover. This is necessary so
that ventilation of the mattress can occur.
My baby's crib with the BabeSafe-wrapped mattress is in my
bedroom and very close to my own unwrapped adult-sized
mattress. Does this matter?
No. The baby's crib can be in your bedroom, and it can be positioned
very close to your own bed if you wish.
How do I clean the BabeSafe cover?
Do not remove the BabeSafe cover from the mattress for cleaning. To
clean the cover, wipe it with bar soap and warm water, and then dry it with a
towel. Do not use chemical bleaches or sterilants to clean the cover.
I've ordered a BabeSafe cover for my baby's mattress but until
I receive it the mattress will be unwrapped. What should I do
1. Remove the mattress from the crib.
2. Fold a few pure cotton sheets or pure cotton towels or pure cotton
blankets to make a thick pad. Use this pad as a temporary "mattress."
3. Place the temporary mattress in the crib . Then place a crib sheet on top
of the temporary mattress and tuck it in securely so that the mattress is
firm and smooth.
4. The baby sleeps on the crib sheet, with a further sheet on top of the
5. Use overblanket/s which are made of pure cotton or pure wool.
6. Do not use any other items of bedding in the baby's crib .
7. When the BabeSafe cover arrives, enclose the baby's crib mattress
(which was previously removed from the crib) in the BabeSafe cover.
Sleep the baby on the BabeSafe-wrapped mattress and using the
specified bedding for a wrapped mattress (see bedding instructions
Can a BabeSafe cover be re-used from one baby to the next?
Provided it has not been damaged during storage, a BabeSafe cover
can be re-used from one baby to the next. The BabeSafe cover should
remain sealed on the mattress during storage.
