The Ikea Vestmarka is a simple sprung mattress at a genuinely low price. It uses Bonnell springs, a connected coil system rather than individual pocket springs, which means you get sturdy, slightly bouncy support without the price tag of fancier constructions. Ikea describes it as medium firm, and at 18cm deep it's shallower than many mattresses, so it sits lower in the bed frame and suits fitted sheets with less depth. It comes in UK Double and UK King only, with a 10-year guarantee. If you want an affordable, no-frills mattress for a spare room or a tight budget, it makes sense. It won't feel plush or contouring, and it isn't trying to.

Assessed from Ikea's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
Why should you choose this mattress?
Price is the obvious draw, but the spec is more reassuring than you might expect at this level. The polyurethane foam comfort layer is 33 kg/m3, a respectable density that should hold its shape better than the very cheapest foams. The Bonnell spring unit runs at 166 springs per square metre, which means firm, even support across the surface, with more motion transfer than pocket springs if you share the bed. It's certified to EN 1957 and BS 7177, the durability and fire safety standards. Ikea backs it with a 10-year guarantee, generous at an affordable starting price, and its brand-wide policy allows a 365-night trial, although that isn't stated on this product page, so confirm before buying.
Key features & layer details
Bonnell springs
A connected coil system at 166 springs per square metre, which means consistent, slightly springy support across the whole mattress. Because the coils are linked, movement travels more than it would with pocket springs, so a restless partner will be more noticeable.
Standard foam
A polyurethane foam layer at 33 kg/m3, which means a decent level of durability for the price rather than a bargain-bin foam that flattens quickly. It softens the feel of the springs a little without adding much sink-in comfort.
Stiff felt
A firm felt layer that sits between the foam and the springs. It stops the foam pressing into the coils, which helps the mattress wear evenly over time.

Best suited for?
Budget buyers
The copy calls it a genuinely low price option, and the 33 kg/m3 foam layer should hold its shape better than the very cheapest foams.
Guest rooms
Described as a no-frills choice for a spare room, it gives sturdy, slightly bouncy support from Bonnell springs without needing a fancier construction.
Back sleepers
Medium firm feel and 166 springs per square metre give firm, even support across the surface, which suits anyone who prefers a flatter, less sink-in sleep.
Heavier sleepers
A connected Bonnell spring unit and a stiff felt layer stop the foam pressing into the coils, which helps the mattress wear evenly over time.
Lightweight side sleepers may find medium firm with Bonnell springs a little unforgiving on shoulders and hips. Couples sensitive to movement should look at pocket sprung options instead, and at 18cm deep it won't suit anyone wanting a tall, plush feel. Single and Small Double sleepers are out of luck: it comes in Double and King only.
Save on an earlier or ex-display model
Some retailers still sell the earlier version of this mattress, or ex-display and returned stock at a lower price. These are the sizes where it costs less than the current model's best price.

FAQ's
Is the Ikea Vestmarka mattress firm or soft?
Ikea describes the Vestmarka as medium firm. The connected Bonnell springs give it a supportive, slightly bouncy feel rather than a soft, contouring one, so back and stomach sleepers are likely to get on with it better than lighter side sleepers.
How thick is the Ikea Vestmarka mattress?
It's 18cm deep, which is on the shallow side. That's fine for support, but it sits lower in the bed frame and gives a flatter, firmer feel than deeper mattresses with thicker comfort layers.
Does the Ikea Vestmarka come with a trial and guarantee?
The mattress carries a 10-year guarantee. Ikea's brand-wide policy allows a 365-night trial, although the trial isn't stated on this specific product page, so it's sensible to confirm with Ikea before you buy.
What sizes does the Ikea Vestmarka come in?
It's available in UK Double and UK King only. There's no Single or Small Double option, so it won't work for kids' beds or narrower frames.
What is the Ikea Vestmarka made of?
It has a polyester ticking cover over polyurethane foam at 33 kg/m3, a stiff felt layer, and steel Bonnell springs at 166 per square metre. It's certified to EN 1957 and BS 7177, the relevant durability and fire safety standards.
