Frequently Asked Questions
What size is a 4ft6 double mattress for triple sleeper and bunk beds?
A 4ft6 double is the standard UK double width, roughly 135cm wide by 190cm long. Always measure your bed's mattress platform and compare it with the size on this listing before ordering, because frames can vary slightly from maker to maker.
Will this double mattress fit the bottom bunk of my triple sleeper?
It is intended for triple sleepers and bunk beds that have a 4ft6 double base, which is usually the bottom bunk. Check the frame's internal dimensions and its maximum mattress depth before buying, so the mattress sits properly inside the bed.
Is a double bunk bed mattress safe to use on an upper bunk?
Only if the bed manufacturer's instructions allow a mattress of this depth. Always check the bed's maximum mattress depth and guard rail height, because a thicker mattress lowers the effective rail. If you are unsure, follow the manufacturer's guidance before anyone sleeps up high.
What age is a double mattress for a triple sleeper suitable for?
It suits children, teenagers and adults who use a double-width bunk, provided the frame allows it. Younger children need a firmer mattress and should only sleep on high bunks if the bed manufacturer's age guidance says so, so read that guidance carefully.
How is this bunk bed double mattress made?
It is sold as a double mattress for triple sleeper and bunk beds, so it is aimed at frames where height is limited. Please check the product description for the full construction details before ordering, as the title does not list every specification.
How firm should a children's double mattress be for growing bodies?
Growing children generally do better on a supportive mattress that is not overly soft, as it helps them lie evenly. Check the firmness described in the product details, and follow your bed manufacturer's guidance, especially for younger children.
What bedding fits a 4ft6 double bunk bed mattress?
Standard UK double bedding is the right size, meaning a double fitted sheet and a double duvet. Check the mattress depth on the listing and choose a fitted sheet with a deep enough pocket so it stays in place.
How long will delivery of this 4ft6 mattress take?
Delivery options and estimated dates are shown at checkout for UK addresses, so you can see timings before you pay. If you need the mattress by a certain date for a new bed, please check the delivery details first.
How do I look after and rotate a double bunk mattress?
Turn the mattress head to foot every few months so wear is spread evenly, and air the room regularly. Spot clean the mattress's own cover with a damp cloth and mild soap, then let it dry fully before making the bed.
Should I choose a double or a kids single mattress for bunk beds?
Let the frame decide. A double mattress is for bunks with a 4ft6 base, such as the bottom bunk of a triple sleeper, while a kids single mattress suits standard single bunks. Measure your bed first, then buy the matching size.
