Envelope Baby Sleeping Bag Infant Sleep Sack Cotton Toddler Swaddle Blanket 115cm Warm Bedding for Autumn Winter Spring Nursery
115cm Cotton Envelope Baby Sleeping Bag for Infants and Toddlers

This envelope baby sleeping bag is a 115 cm bedding option for infants and toddlers, available in spring and autumn models and winter models. The outer fabric is colour cotton, the lining is pure cotton at 95% and above, and the filling is polyester fibre. Instead of using loose blankets that can be kicked away, the envelope design keeps a layer of warmth around the child during sleep. The bag comes as a single sleeping bag, making it a focused nursery item rather than a multi-piece set. It suits parents who want a simple, cotton-lined sleep sack for use in a cot, pram or travel cot. The two model options let you select a version for milder seasons or for colder winter conditions, based on the temperature of the room.
Features and Construction

The construction of this sleeping bag centres on three stated materials: colour cotton on the outside, pure cotton lining at 95% and above, and polyester fibre filling. The envelope shape provides an opening for placing the baby inside, then closing the bag around the body. This design is intended for sleep and nap routines, when a parent wants a contained layer rather than a loose sheet or blanket. The 115 cm length gives room for a baby or toddler to lie with coverage along the body. The source text also lists two model options, so buyers can match the bag to the season rather than using one weight year-round.
Material and Build
The fabric is listed as colour cotton, which forms the outer surface of the sleeping bag. Inside, the lining is pure cotton at 95% and above, giving a cotton-rich layer next to the child. The filling is polyester fibre, which provides warmth and body to the bag. These three layers are stated directly in the source text, and no additional coatings, waterproof membranes or temperature ratings are provided. The envelope opening and fastening are part of the design, but the exact closure type is not specified. The bag is supplied as a single item, with no extra inserts or covers listed in the package contents.
Size and Practical Fit
The stated size is 115 cm in length. This is the only measurement given in the source text, so it is the key figure to check before buying. A 115 cm sleeping bag is intended to cover an infant or toddler during sleep, with enough length for the child to lie inside without the bag being pulled tight. As no width, weight limit or age range is provided, the length should be compared with the child's height and the cot or pram dimensions. The envelope shape is designed to make it easier to place a sleeping child into the bag, then close it around the body.
Uses and Placement

This sleeping bag is intended for sleep and bedding use, including nursery routines, nap times and travel. It can be used in a cot, pram or travel cot where a contained sleep layer is preferred over a loose blanket. The two model options make it possible to choose a spring and autumn version or a winter version, depending on the season and the warmth of the room. Because the lining is cotton-rich, it is positioned as a next-to-skin layer, while the polyester fibre filling adds warmth. The bag is not described as a swaddle with arm restraints, so it should be treated as a sleeping bag rather than a restrictive wrap.
Event or Professional Use
For childcare settings, nurseries and family homes, a sleeping bag can simplify nap time by providing each child with a personal bedding layer. The 115 cm length and envelope opening allow staff or parents to place a child inside and close the bag without relying on a loose blanket that may be kicked off. The two season options help match the bag to the room temperature or the time of year. The stated materials are colour cotton, pure cotton lining at 95% and above, and polyester fibre filling, all of which are factual details from the source text. No professional certifications or safety ratings are provided in the source text.
Everyday Home Use
At home, this sleeping bag fits into a daily nap and night-time routine. It can be used in a cot or travel cot, and the envelope design makes it easier to settle a sleepy child without rearranging separate blankets. The 115 cm length gives coverage along the body, while the cotton-rich lining sits against the skin. The outer colour cotton fabric is the visible layer, and the polyester fibre filling provides the warmth. Because the source text does not specify washing temperatures, drying methods or ironing instructions, parents should follow the care label supplied with the item.
Benefits and Buying Value

The main practical benefit of this sleeping bag is that it replaces loose blankets with a single contained layer. The envelope shape and 115 cm length support this by covering the child while keeping the bedding in one piece. The choice of spring and autumn or winter models adds flexibility, so the same style of bag can be used in different seasons. The materials are stated clearly, with colour cotton on the outside, pure cotton lining at 95% and above, and polyester fibre filling. The package contains one sleeping bag, so there is no need to account for extra pieces.
Reuse and Low Maintenance
As a single-piece sleeping bag, this item is straightforward to store, fold and reuse between naps or between children. The cotton-rich lining and colour cotton outer are the stated materials, and the polyester fibre filling provides the warmth. No specific washing, drying or ironing instructions are given in the source text, so the care label should be checked before cleaning. Because the bag is not described with removable layers or covers, it should be treated as a complete unit. Reuse depends on following the label and keeping the bag clean and dry between uses.
Why Choose This Product
This sleeping bag is a practical choice for parents who want a cotton-lined envelope sleep sack in a 115 cm length. It offers two model options, spring and autumn models and winter models, so the warmth level can be matched to the season. The fabric is colour cotton, the lining is pure cotton at 95% and above, and the filling is polyester fibre, all stated in the source text. The package contains one sleeping bag. No age range, weight limit, tog rating or safety certification is provided, so buyers should check the 115 cm length against their child and cot before purchase.
