Ash, oak or mahogany: which wood should you choose for a bed?
Ash, oak or mahogany for a bed? All three are equally strong in a bed frame; they differ in look, how they age and price. A side-by-side comparison.
In short: In a bed frame, ash, oak and mahogany (sapeli) are practically equal in strength, so you choose on looks and budget. Ash is pale, has the most visible grain, takes paint very well and is the base option. Oak is golden-brown with a rustic grain and looks best left natural. Mahogany is reddish-brown and the darkest of the three. Oak and mahogany each add the same fixed premium over ash.
The wood species is the first choice that changes both the look and the price of a solid wood bed. Massif works with just three: ash, oak and mahogany (sapeli). Here's how they compare in numbers, in appearance and in how they look a few years on.
How do ash, oak and mahogany compare?
| Ash | Oak | Mahogany (Sapeli) | |
|---|---|---|---|
| Latin name | Fraxinus excelsior | Quercus robur | Entandrophragma cylindricum |
| Janka hardness (approx.) | ~1,480 lbf | ~1,120 lbf | ~1,410 lbf |
| Dry density (approx.) | ~710 kg/m³ | ~675 kg/m³ | ~640 kg/m³ |
| Colour | pale, straw-yellow | golden-brown | deep reddish-brown |
| Grain | bold and clearly visible | rustic, irregular | distinctive figure |
| Ages towards | warm honey | caramel | burgundy |
| Best finish | natural, paint or stain | natural | natural |
| Price on a bed | base | fixed premium | same premium as oak |
Does Janka hardness matter for a bed?
Janka hardness measures how much force it takes to press a steel ball into the wood. The higher the number, the harder the surface is to dent. Many people are surprised that oak, the textbook "hardwood", scores lowest of the three, and ash highest.
For a bed, this matters little. Janka hardness tells you about the surface (a knock from the vacuum cleaner, a dropped key), not about how sturdy the frame is. A bed's strength comes from the size of the timber and the joints. Massif beds use mortise and tenon joints with no metal brackets, and across all three species the structural strength is practically the same. For more on what a frame can carry, see our guide to bed strength.
Density points the same way: ash is the heaviest, mahogany the lightest. For a bed you assemble once and rarely move, that won't change your choice either.
Ash: pale, bright and made for paint
Ash is pale and straw-coloured, with a bold, very visible grain. Left natural, it gives a bright room with a Scandinavian feel. It's also the species that takes paint best: if you want a white, grey, green or any other RAL colour bed, ash is the natural choice. Paint is included in the price, just like the natural finish.
Over time, natural ash deepens towards a warm honey tone. If you want a darker tone from the start, you can choose a stain (one coat of stain plus lacquer, at extra cost).
Ash is the base species, so it's the most affordable option on any model.
Oak: rustic, warm and best left natural
Oak is golden-brown with a more rustic, irregular grain whose pattern varies from board to board. That irregularity is exactly why people choose it, and why we recommend leaving oak natural: paint would hide the very thing you're paying extra for.
Over time, oak deepens towards caramel. It suits rooms with wooden floors, exposed beams or older furniture, and bedrooms where you want a warm, homely feel.
Mahogany (sapeli): the darkest, with a distinctive figure
The mahogany we use is sapeli, a deep reddish-brown wood with a distinctive figure that shifts with the angle you look at it from. It's the darkest of the three, and it darkens further towards burgundy.
Mahogany makes for an elegant, classic bedroom and works well against pale walls that set it off. Like oak, it looks best natural. Note that some slim models aren't made in mahogany, so check the product page.
How does the wood change over time?
All three species darken with age, especially where light falls on them. It's a normal process in solid wood, not a defect:
- ash moves from straw-yellow towards warm honey;
- oak moves from golden-brown towards caramel;
- mahogany moves from reddish-brown towards burgundy.
If the bed stands by a window, the exposed side may darken faster. Two coats of polyurethane lacquer protect the surface but don't fully stop the wood from ageing. For care tips, read how to look after a solid wood bed.
Natural, painted or stained?
| Finish | What it is | Cost | Choose it when |
|---|---|---|---|
| Natural | 2 coats of clear lacquer | included | you want the wood to show as it is |
| RAL paint | 2 coats of polyurethane paint, any RAL colour | included | you want a specific colour; best on ash |
| Stain | 1 coat of stain + lacquer | extra | you want a darker tone with the grain still visible |
The simple rule: if you're paying extra for oak or mahogany, leave them natural. If you want colour, choose ash and paint it.
Which wood suits which room and taste?
- Small or dim room: natural ash, or ash painted a light colour. It makes the space feel more open.
- Scandinavian or minimalist bedroom: natural ash. It pairs well with our minimalist beds.
- Child's or teenager's room: painted ash, matched to the rest of the room.
- Home with wooden floors, beams or rustic furniture: natural oak.
- Classic, elegant bedroom with pale walls: natural mahogany.
- Tight budget: ash. You skip the species premium without giving up any strength.
If you're matching existing furniture, photograph it in daylight and compare it with the photos on the product pages.
Frequently asked questions
Which wood lasts longest?
In a bed, all three are practically equal structurally. The differences are in looks and price, not lifespan.
Can I paint an oak bed?
You can, but we don't recommend it: oak's rustic grain is the reason to choose it, and paint covers it up. For a painted bed, ash takes paint better and costs less.
Do two beds in the same wood look identical?
Not quite. Solid wood is a natural material, so grain and tone vary a little from board to board, especially in oak. The photos show the character of the species, not the exact pattern of your bed.
Why do oak and mahogany cost the same?
Their premium over ash on beds is the same, so choosing between them is purely a matter of taste.
Does painted wood darken too?
What darkens is natural, exposed wood. On a painted bed, the colour comes from the paint covering the wood, so you won't see the wood's change in tone.
