Bunk beds with pull out trundles are worth considering because they give you three beds in the footprint of one, without committing a whole room to guests. The trundle slides away under the bottom bunk when it is not needed, then rolls out for sleepovers, visiting cousins or a child who wants company. For homes where every square metre counts, that flexibility is difficult to achieve any other way.<\/p>\n
Many of the frames in our modern bunk beds UK sale<\/a> collection can be paired with a trundle, and they sit within a wider bedroom furniture UK<\/a> range that helps the rest of the room work around them. Below, we explain the main benefits, the measurements to check and the details that make a trundle comfortable to use night after night.<\/p>\n A trundle is a low bed frame on castors that sits beneath the bottom bunk. It holds its own mattress and is pulled out by hand when needed. Some trundles are separate units that slide into the space under the bed, while others are built into the bunk bed frame and run on guides.<\/p>\n It is worth separating trundles from under bed drawers. Drawers are designed purely for storage and are not built to carry the weight of a sleeping child. A trundle is a proper sleeping surface, designed to take a mattress and the person on it.<\/p>\n Sleepovers without the airbed.<\/strong> Anyone who has inflated an airbed at ten o’clock at night will appreciate a trundle. It is ready in seconds, it sits on a proper base and it does not slowly deflate by morning. Children tend to sleep better on it too.<\/p>\n Visiting family.<\/strong> Plenty of UK homes do not have a dedicated guest room. A trundle beneath the children’s bunk bed means a grandparent can have the spare double while a visiting cousin bunks in with the children.<\/p>\n Three children, one room.<\/strong> In growing families, there can be a stretch of years when three children share. A trundle bridges that gap without needing a bigger room or a second bunk bed.<\/p>\n Comfort for younger siblings.<\/strong> Most guidance advises that the top bunk is not used by children under six. A trundle gives a younger child a low, safe place to sleep near older siblings until they are old enough for the upper bunk.<\/p>\n A floor that stays clear.<\/strong> When the trundle is tucked away, the room returns to normal. There is no folded mattress leaning against a wall and no camp bed taking up space in a cupboard.<\/p>\n A trundle needs space in two states: closed and open. The closed footprint is simply that of the bunk bed. The open footprint is the important one.<\/p>\n Measure the depth of the trundle, which is usually close to the width of a single mattress, and add it to the distance from the wall to the front of the bunk bed. That is how far into the room the bed will reach when it is fully pulled out. Then check that:<\/p>\n Also check the clearance beneath the bunk bed. Skirting boards, thick carpet and rug edges can all catch on castors, so a little extra height under the bottom bunk makes the trundle easier to use.<\/p>\n The trundle mattress is often an afterthought, but it is the one most likely to be used by guests and occasional sleepers, so comfort matters. The main constraint is depth. A trundle has limited height, and too thick a mattress will stop it sliding back under the bunk. Manufacturers usually specify a maximum depth, so check this before buying.<\/p>\n Within that limit, look for a mattress that offers decent support rather than simply the thinnest option available. Our modern mattresses UK<\/a> range includes shallower options that suit trundles. A medium firmness tends to suit the widest range of sleepers, which matters when you do not know who will use the bed next.<\/p>\n Remember that mattresses for the upper bunk also have a maximum depth, set so that the guard rails remain effective. Check all three mattresses against the manufacturer’s guidance.<\/p>\n A few small habits make a trundle much more pleasant to live with.<\/p>\n Keep it made up.<\/strong> If the trundle has its own fitted sheet, pillow and duvet ready inside, setting it up takes a moment. A breathable mattress protector keeps it fresh between uses.<\/p>\n Use it for storage, carefully.<\/strong> When the trundle is not needed for sleeping, it can hold spare bedding or soft toys on top of the mattress. Avoid heavy items that could damage the mattress or make the trundle hard to pull out.<\/p>\n Think about flooring.<\/strong> Trundles glide easily on wooden floors and low pile carpet. On a thick rug, castors can drag. Placing the rug so its edge stops short of the trundle’s path solves this.<\/p>\n Mind little fingers.<\/strong> Teach younger children to pull the trundle out by the front edge, not from underneath, and to push it back gently.<\/p>\n A trundle is not the only way to fit more sleeping space into a room, so it is worth comparing.<\/p>\n A trundle sits neatly in the middle, offering a proper bed without extra height and without the need for separate storage space.<\/p>\n If you like the idea of a trundle but are not sure a bunk bed suits your room, many single beds also come with trundles. These are a good option for a child who sleeps alone but hosts friends regularly. Our children’s beds UK<\/a> collection includes styles that pair well with trundle units. For older children and teenagers, our guide to upholstered single beds for UK children and teenagers<\/a> covers designs that suit a more grown up room, and our article on mattress firmness labels in UK testing<\/a> explains how to judge comfort when choosing mattresses for every bed in the room.<\/p>\n Because a trundle sits low to the floor, it changes how the bottom of the bunk bed looks. A frame with a trundle reads as more solid and substantial than one with an open space beneath, so it is worth keeping the surrounding furniture simple and light.<\/p>\n Coordinate the bedding across all three beds. Matching fitted sheets with different duvet covers gives each sleeper their own identity while keeping the stack visually tidy. When the trundle is closed, a valance or neatly tucked throw on the bottom bunk can hide the front edge if you prefer a cleaner line.<\/p>\n Lighting matters too. The trundle sleeper sits lowest in the room and furthest from most bedside surfaces, so a small plug in night light or a lamp on a low shelf nearby makes it more welcoming for guests who do not know the room.<\/p>\n Finally, keep a clear zone in front of the bed. A small rug placed to one side of the trundle’s path softens the floor without getting in the way, and it gives children somewhere comfortable to sit when the trundle is pulled out for a film night or a story before bed.<\/p>\n A trundle bunk bed makes most sense if you host overnight guests regularly, have a family that may grow, or simply want the reassurance of a spare bed without giving up floor space. It makes less sense if the room is so tight that pulling the trundle out would block the door, or if you rarely need the extra bed at all.<\/p>\nWhat a Trundle Actually Is<\/h3>\n
