Cot & Cot Bed Mattresses

Sort by:

Your little one's safety is the most important consideration when choosing a cot or cot bed mattress, that's why all our British-made mattresses meet BS EN 16890:2017. They've been tested with specialist machines designed to ensure they offer maximum support and comfort for your baby.

Choose from a range of features including mattresses treated with a unique Purotex technology which is an hypo-allergenic treatment that uses probiotics to reduce moisture build up and create a barrier against dust and allergens, stopping them from penetrating the mattress.


Find The Size That Fits Your Cot

A cot bed mattress should match the internal length and width of your cot so there are minimal gaps at the sides. The fit of a baby cot mattress within the cot frame is very important, as it ensures that the cot and mattress combination is safe to use together. When shopping for a cot, the product information will generally specify the correct mattress dimensions you require. Additionally, the packaging and the assembly instructions that the cot comes with will also state the recommended mattress size.

Support And Comfort Basics

A firm sleep surface is important for providing the baby with a safe sleep environment that minimises the risk of SIDS and suffocation. The cot mattress should support the baby's shoulders, hips and legs without dipping. Make sure the sleep area is kept clear, with only the essential bedding items. Adding unnecessary items such as toys or pillows to the cot increases the risk of suffocation and should be avoided.

Safety You Can Trust

Infant sleep surfaces used with a cot mattress are designed to comply with BS EN 16890:2017., and clear product notes help you set up with confidence. Always follow the mattress height and cot setting in your manual so the sleep space feels safe for every nap and night.

Make Changes Quick And Quiet

Sheets that fit well save time at night, and you can match sizes easily in Cot & Cot Bed Fitted Sheets. Keep spare sets close by in simple baskets, and a small unit from Nursery Storage helps you reach what you need in the Baby Changing area without turning on bright lights.

Comparing Different Baby Cot Mattress Options

  • Fibre-filled cot mattresses: we have a range of fibre-filled cot mattresses, handmade with different fibre-fill options that create a firm and supportive sleep surface that also features hypo-allergenic properties. The material allows for good airflow in bed cots with a mattress, while the internal waterproof membrane protects the core.
  • Pocket Spring and Fibre Hybrid mattresses: this cot mattress combines the support of a pocket spring mattress with the added support of an extra fibre-filled layer, allowing for improved airflow and comfort.

Materials And Daily Care

The cot mattress options we range use materials that promote breathability and airflow, but they can still be affected by overly moist conditions. To better protect your cot mattress from mould growth, make sure to keep the nursery well ventilated and occasionally air out the mattress. Also consider using a mattress protector to protect the mattress from any spills or leaks. To promote even wear across the surface, it is also best to occasionally rotate the mattress.

Room Planning Without The Guesswork

Place the cot where the air feels fresh and the light is soft so the cot mattress feels welcoming at bedtime. Keep a chair nearby for soothing, and keep night items in one place so your hands can reach them while your baby stays settled.

Delivery, Help, And Support

Delivery is made to your front door, with typical processing taking 1-3 business days before dispatch. Delivery typically occurs 7 to 10 business days after the item ships from the warehouse. It is best to check delivery timeframes and expectations for your address.

Boori does not offer in-house assembly, and the team can recommend experienced third-party assemblers for furniture if you want help. Weekday support can assist with parts or delivery questions for items that sit near your cot mattress.

Warranties And Product Guidance

Warranty time frames vary by category, ranging from 1 to 5 years, as listed on product pages. Registering eligible items can extend coverage for many timber pieces in your nursery plan. For any setup questions, you can contact the team on weekdays, and stores can provide general guidance on weekends, so your cot mattress is set up in a clear, simple plan.

Quick Buy Guide

Small, clear checks make choosing easy and help the first night run smoothly.

  • Correct Size: Measure the internal length and width of your cot, then match them to the listing so the cot mattress fits the frame without gaps.
  • Right Depth: Check the depth in the product notes so the top sits at the safe level for your cot setting and your reach.
  • Sheet Fit: Select fitted sheets in the same size range to ensure the corners stay secure after washing and drying.
  • Easy Clean: Add a breathable protector and keep one spare ready so night swaps are fast and quiet.
  • Storage Plan: Place spare bedding in one basket and nappies in another, so you can easily find what you need in low light.

FAQs

What is the difference between a cot mattress and a cot bed mattress?

A cot mattress fits a smaller cot (typically around 120 × 60 cm), while a cot bed mattress fits a larger cot bed (often around 132× 70 cm) that converts and lasts longer. The larger size gives extra room as the child grows; both should fit the frame snugly with no gaps.

What to look for in a cot mattress?

Choose a firm, even surface that keeps its shape, with a cover that's breathable and washable. Check the exact size against your frame, look for clear safety certification, and ensure the edges sit snugly so there are no gaps around the sides.

What kind of mattress is best for a cot bed?

A firm mattress with good airflow and a snug, exact fit is best. Many parents pick a dual-sided option (firmer for early months, slightly softer later) if it's clearly labelled. Whatever you choose, pair it with a fitted sheet and keep the sleep surface clear.

Can I use a travel cot on holidays?

Yes, follow your model's guide and use a travel cot mattress or a travel cot with mattress that matches the maker's size so the surface stays flat and easy to clean.

Where can I keep spare bedding and nappies?

Place simple baskets in one tidy unit and keep them near the cot, and you can find helpful pieces in Nursery Storage so your cot mattress sits in a calm, organised space.
