Assessed from Ikea's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
The main reason to choose the Vadso is price with a safety net attached. At £89 to £99 it is a very low price for a sprung mattress, yet Ikea still offers a 365-night trial and a 10-year guarantee, so you can try it at home for a full year with little risk. The firm feel and Bonnell spring unit give a uniform, supportive surface, which back sleepers who like a solid base tend to get on with. It arrives roll packed, which means it's easier to carry upstairs than a traditional flat mattress. It's basic, but for a spare room or a first bed it does the job honestly.

Who's it NOT for?
Couples who share a bed may struggle, as the connected Bonnell springs transfer motion and you'll feel a partner turning over. At 17cm deep with a firm feel, it's also a poor fit for lightweight side sleepers who need pressure relief at the shoulder and hip, and anyone wanting a plush, hotel-style surface should look elsewhere.

Across 585 reviews on ikea.com the Vadso averages 3.8 out of 5, with owners praising its comfort and value for money, and some noting the firmness works well for back support. Common concerns are durability after extended use and firmness not matching expectations.

Is the Ikea Vadso mattress firm or soft?
Ikea describes the Vadso as firm. The polyurethane foam comfort layer sits over stiff felt and a Bonnell spring unit, so the feel is solid and uniform rather than cushioned. Some owner reviews mention the firmness suiting back support, though a few found it didn't match their expectations.
Does the Ikea Vadso come with a trial and guarantee?
Yes. Ikea offers a 365-night trial, so you can sleep on it at home for a full year, along with a 10-year guarantee. That's generous cover for a mattress starting at £89.00, and it takes much of the risk out of buying at this price.
How deep is the Ikea Vadso mattress?
The Vadso is 17cm deep, which is shallow compared with most adult mattresses. That makes it a reasonable fit for bunk beds, guest beds or children's rooms, but heavier adults or anyone used to a deeper mattress may find it a little thin for nightly use.
Is the Ikea Vadso good for couples?
It's a little limited for couples. The Bonnell spring unit is connected, so movement transfers across the mattress and you're likely to feel a partner shifting in the night. If you share a bed and either of you sleeps lightly, a pocket sprung mattress would isolate movement better.
What sizes does the Ikea Vadso come in?
The Vadso is available in UK Single and UK Double, priced from £89 to £99. It arrives roll packed, which makes it easier to move through hallways and up stairs before you unroll it on the bed base.
