One sheet on the bed. A clean one in the drawer.
And the mattress, always safe.
For the pram, the bedside crib, the cot or the bed. For naps on the go and long nights.
Two fitted sheets and a waterproof protector. All three pieces the same size.
Because a leak at three in the morning shouldn’t mean changing the whole bed.
Off with one sheet. On with the other.
The protector has already done its job.
The mattress stays dry.
Nothing to match up. Nothing to buy separately.
And back to sleep. Everyone.
Mommybelly Set of 2 Fitted Sheets + Waterproof Mattress Protector | 100% Cotton Jersey Oeko-Tex | 13 Sizes, from Pram to Single Bed

























Mommybelly Set of 2 Fitted Sheets + Waterproof Mattress Protector | 100% Cotton Jersey Oeko-Tex | 13 Sizes, from Pram to Single Bed
Two cotton jersey fitted sheets and a waterproof mattress protector that doesn’t crinkle. All three pieces the same size, in 13 sizes: from pram to single bed.
Are you pregnant or have you just had your baby? Then you know sleep is everything, and that a leak at three in the morning ruins the night. This set solves exactly that: two fitted sheets and a mattress protector, all three pieces the same size. One on the bed, a clean one in the drawer and the mattress covered at all times.
- 🛏️ What’s in the box. 2 cotton jersey fitted sheets elasticated all the way round and 1 waterproof terry protector with elastic on all four corners. Nothing to match up and nothing to buy separately.
- 👑 Real cotton, with the number up front. Fitted sheets in 100% cotton jersey at 140 gsm, ring-spun and stretchy both ways. They keep gripping the mattress wash after wash, without shrinking or popping off the corner at night.
- 💧 A protector that doesn’t crinkle. Knitted terry at 160 gsm (80% cotton, 20% polyester) on the side that touches the skin, with a polyurethane membrane underneath. It absorbs on top and stops the liquid below. No stiff film that sounds like a carrier bag.
- 🎯 From pram to single bed. Thirteen sizes and a pocket depth of 10 to 30 cm depending on size, so it grips thick mattresses too.
- 🛡️ Oeko-Tex Standard 100. Free from harmful substances, made for the sensitive skin of babies and children.

No more protectors that crinkle and trap heat.
Traditional protectors have one problem: they sound like a carrier bag every time baby moves.
Not this one.
On top, cotton terry that absorbs.
Underneath, a thin membrane that stops liquid.
Baby sleeps on cotton.
And you don’t hear crinkling from across the room.
There’s always a spare.
Always.
One in the cot.
One in the wash.
And the protector underneath, doing its job.
For the leaky nappy, the milk that comes back up and the accidents of potty training.
And since the two sheets have different prints that go together, changing the bed looks good too.

Today they’re sheets. Tonight, a calmer early morning.
With a baby at home, rest is everything. And a leak in the small hours ruins it.
With this set, not so much.
One off, the other on, and the mattress stays dry.
Five minutes and back to bed.
Don’t take our word for it. Ask the families already using them.

Now it’s your move.
What if you leave it for tomorrow… and the leak happens tonight?
They’re not just sheets. They’re one less night changing the whole bed.
For the pram, the bedside crib, the cot or the bed.
You can stick with the crinkly protector and the sheet that pops off the corner.
Or you can always have a clean spare and a safe mattress.
But don’t wait too long.
Some sizes fly. And when one sells out, it can take a while to come back.
No endless stock, no giant warehouses.
Just a small brand that wants everyone at home to sleep a little better.

























They’re just sheets.
But when at three in the morning you only have to change one… you know you got it right.
