How we test products
Our mission is to take the guesswork out of finding the perfect sleep products.
We've dedicated hundreds of hours to testing mattresses and sleep accessories, and rely on a team of testers of differing weights, temperature preferences, and sleeping positions to evaluate each product.
Tested products are granted the Sleep Hero tested stamp of approval, a mark of our review's reliability.
If we haven't personally tested a product, please be assured that we invest significant time and energy into scouring the UK market and researching the best recommendations, and we work with a team of sleep experts who review our articles, ensuring that the insights we provide are not only relatable but also reliable.
What is a trundle bed?
A trundle bed is typically a single bed with a pull-out bed underneath. 🤯
It can be used as an extra guest bed or to extend a single bed into a king or super king.
So, how do you know whether you need a trundle bed or a sofa bed?
We’ll break down the many benefits of a trundle bed below. 👇
Types of trundle beds
“Trundle” isn’t the prettiest word, but these convenient guest beds can actually look very stylish. ✨️
The trundle bed you need depends on your individual requirements.
Trundle bed frame
A trundle bed frame is one of the most popular types available. 🏆
They are typically made from wood or metal and are higher up than a regular bed frame. 👆
This gives plenty of space for a trundle to slide under and be stored away.
They’re an excellent option for guests or kids who need more sleeping space but don’t have a lot of room.
Trundle bed daybed
A day bed trundle is a great option for those who want a pretty sofa-inspired bed to upgrade overall decor. 😍
Typically, trundle day beds can look similar to a sofa with a more minimalist design.
They look great up against the wall or bedroom window or as a cosy reading nook in the living room. 🛋
Trundle bed bunk bed
A trundle bunk bed provides the most amount of sleeping space. 🌌
They look similar to a standard bunk bed but have an extra bed underneath that slides out, offering up to 3 beds overall.
They could be a good option for siblings that share a room and don’t have much space to play or those who have regular sleepovers. 🙋
Trundle bed with storage
A trundle bed with storage is similar to a trundle bed frame, except with additional storage options.
This typically comes in the form of drawers integrated into the underneath trundle.
If you need an extra bed and some extra room for bedding or toys, a trundle bed with storage is a great idea. 🧸
Trundle bed sizes
Trundle beds come in various sizes.
In this article, we recommend single trundle beds but pull out double beds are also available for those that need more sleeping space.
A single trundle bed has a size of 3ft (90 cm) when closed, but will pull out into a double, king, or super king-size when both beds are put together.
When measuring your space, it's important to take the underneath section into account when measuring for a single bed that turns into a double, king, or super-king.
Our size guide below gives you an idea of all standard UK mattress sizes:
- Trundle bed small single: 75 x 190 cm (2'6 x 6'3")
- Single bed with trundle: 90 x 190 cm (3' x 6'3")
- Trundle bed small double: 120 x 190 cm (4' x 6'3")
- Double bed with trundle: 135 x 190 cm (4'6" x 6'3")
- Trundle bed king size: 150 x 200 cm (5’ x 6’6”)
- Trundle bed super king size: 180 x 200 cm (6’ x 6’6”)
Please note: these are sizes for UK standard mattresses.
Most trundles will be slightly above this due to the additional frame around the edge of the trundle bed.
