When furnishing a bedroom, many people invest considerable time choosing the mattress, bed frame, and bedding, yet often overlook the height of the bedside table. It is only after moving in that the problems become apparent – your phone is just out of easy reach, you have to twist sideways to pick up a glass of water, and the lamp never seems to cast its light at quite the right angle. So how tall should a bedside table be? There is no single correct answer, but there is a set of principles to follow. This guide will help you find the ideal height by examining four key factors: the relationship between the bedside table and the mattress surface, the crucial role of mattress thickness, real‑world usability, and your personal sleeping habits.
Should the bedside table be higher or lower than the mattress? – Stop overthinking it
This is the first question many people ask when choosing a bedside table: should it sit slightly above the mattress, or slightly below?
Drawing on the advice of numerous interior designers and furniture specialists, the ideal answer is that the tabletop should be level with the top of the mattress, or no more than 5–10 cm higher. Interior design expert Melissa Denham even suggests that the height deviation should not exceed 5 cm either way from the mattress surface. The reasoning is rooted in ergonomics – when the bedside table is aligned with the mattress, you can reach for items while lying or reclining with your arm at its most natural angle, without needing to lift or lower it awkwardly.
But what if you have to choose between “higher” and “lower”? Slightly higher is better than slightly lower. If the table is a little taller than the mattress, your arm will tilt gently downwards when reaching, which still feels natural. If it is too low, however, you will have to twist, bend, or even lean half out of bed to grab things – an effort that often leads to spilled drinks or knocked‑over objects. That said, a table that is too high is also problematic: not only does it make reaching uncomfortable, but it can also feel visually oppressive and throw off the room’s overall balance.
Why mattress thickness matters more than you think
Modern mattresses vary enormously in thickness. A standard pocket‑spring mattress is typically 22–28 cm thick, but thicker models – especially those with memory foam or latex layers – can reach 30 cm or more. A 30‑cm mattress atop a bed frame may give a total sleeping surface height of 60–65 cm, while a slim 22‑cm mattress on a low frame might measure only around 45 cm. If you choose your bedside table based solely on the frame, ignoring the mattress, the final height can be dramatically off.
Consider this: the same bed frame, paired with a 22‑cm thin mattress versus a 30‑cm thick one, changes the sleeping surface height by 8 cm – and that 8 cm can be the difference between a comfortable reach and an awkward stretch. The correct method, therefore, is to measure from the floor to the top of the mattress after the bed is fully made. That figure is your reference ideal height. For particularly thick mattresses (over 35 cm), it is advisable to raise the bedside table to around 60–70 cm.
If you prefer a low bed frame with a slim mattress, a low‑profile bedside table – typically 40–50 cm high – is a more suitable choice, as it maintains harmonious visual proportions with the low sleeping surface.
Real‑world usability: the moment you reach out from bed
A difference of just a few centimetres can make a world of difference in everyday use. Let’s consider a few typical scenarios:
Scenario 1 – reaching for a glass of water at night. Half‑asleep, you stretch out your hand to find your water glass. If the table is level with the mattress, your arm extends horizontally and you grasp the glass with ease; you can drink and put it back without even opening your eyes. If the table is too low, you must twist, fumble, and reach downwards – not only risking a spill, but also waking yourself up completely.
Scenario 2 – turning off the morning alarm. Your phone is buzzing on the bedside table. With a well‑matched height, you simply reach over and silence it. With a mismatched height, you may have to sit up just to press the screen – and once you are sitting up, falling back asleep becomes much harder.
Scenario 3 – reading before sleep. The angle of your bedside lamp is crucial when you lean back to read. If the table is too high, the light shines directly into your eyes from above; if it is too low, the mattress blocks the beam. Only when the height is correct does the lamp cast comfortable, useful reading light.
Finding the balance that suits your sleeping habits
Beyond mattress thickness and frame height, your personal habits are equally important in determining the ideal table height.
If you tend to sleep on your side: when lying on your side, your arm naturally hangs slightly lower than when you are on your back. In theory, a table slightly below the mattress might feel more comfortable. However, since you will not stay in one position all night, the level‑or‑slightly‑higher rule remains the safer choice.
If you like to read or use devices propped up in bed: in a semi‑reclined posture, your arm extends at a level slightly above the mattress surface. In this case, a table that is 5–8 cm higher than the mattress will feel more comfortable.
If you have limited mobility: for older adults or anyone with back problems, a bedside table that is slightly higher than the mattress reduces the need to bend and stretch, making it easier to use.
If you favour a minimalist, low‑profile bedroom aesthetic: a low‑profile bedside table paired with a thin mattress can create an open, airy feel. The catch is that the mattress itself must not be too thick – otherwise the low table will look out of proportion.
Material choice also affects the user experience. A walnut ash wood bedside table not only offers warm texture and excellent durability, but its natural grain and colour can blend with many bedroom styles. More importantly, solid wood tables can often be made to order – if standard sizes do not suit your measurements, customisation is a reliable way to achieve the perfect height match.
Conclusion
So, back to the original question: how tall should a bedside table be? The answer is not a fixed number, but a simple formula – measure the height from the floor to the top of your mattress, then choose a table that is level with that height, or up to 5–10 cm taller.
Remember, a bedside table is not an isolated piece of furniture; it is an extension of your bed. Its sole purpose is to make every movement you make in bed more comfortable and natural. Getting the height right starts with matching the mattress – measure its thickness, calculate the total bed height, and fine‑tune according to your habits. These three steps will lead you to that “just right” height.
The next time you shop for a bedside table, take a tape measure with you – measure the mattress first, then choose the table. Those extra two minutes will repay you with comfort and convenience every single day.
