The IKEA Asvang and Agotnes are two of the most affordable foam mattresses from IKEA, but they differ primarily in thickness and feel. The Asvang is thicker at 4 ¾ inches for a slightly more supportive feel, while the Agotnes is thinner at 3 ⅞ inches, making it suitable for spaces with height restrictions like bunk beds or trundles.
Here’s a detailed look at both mattresses to help you decide which one is right for your space and needs.
IKEA Asvang Foam Mattress
The Asvang is a popular entry-level foam mattress designed for simplicity and incredible value. As one of IKEA's most budget-friendly options, it offers a single layer of firm polyurethane foam, roll-packed in a box for easy transport. Its main appeal is its low price point and washable cover, making it a common choice for kids' rooms, guest beds, and temporary living situations.
- What it is: A basic, firm foam mattress made from a single block of polyurethane foam.
- Key features: 4 ¾" thickness, firm feel, zippered cover is removable and machine washable, roll-packed for easy transport.
- Price: ~$179 (Full)
- Dimensions: Available in Twin, Full, and Queen sizes, all with a thickness of 4 ¾".
- Materials/Construction: A solid core of polyurethane foam topped with a quilted mattress cover consisting of recycled polyester filling and a polyester fabric top.
- Pros: Extremely affordable price point. Thicker profile offers more cushion than the Agotnes. Removable, machine-washable cover makes cleaning easy. Easy to get home and set up yourself. A solid choice for a child's first bed or an infrequent-use guest room.
- Cons: Thin profile (under 5 inches) isn't supportive enough for most adults for daily use. Very firm with minimal sink or pressure relief. Off-gassing smell is common after unboxing.
The Asvang is ideal for those who need a mattress for a child's room or a guest bed that will only be used occasionally, where budget is the top concern.

IKEA Agotnes Foam Mattress
The Agotnes foam mattress is another ultra-affordable, no-frills option from IKEA. Like the Asvang, it features a single layer of firm foam and comes roll-packed. Its distinguishing feature is its very low profile - at under 4 inches thick, which makes it one of the thinnest mattresses IKEA offers. This makes it a specialized solution for bunk beds, trundle beds, and daybeds that require a shorter mattress to be safe and functional.
- What it is: An extra-thin, firm foam mattress designed for space-conscious beds.
- Key features: 3 ⅞" thickness, firm feel, removable and washable cover, roll-packed.
- Price: ~$179 (Full)
- Dimensions: Available in Twin and Full sizes, all with a thickness of 3 ⅞".
- Materials/Construction: A single layer of polyurethane foam core with a non-woven polypropylene cover.
- Pros: Extremely low price. Very thin profile is perfect for bunk beds, daybeds, and trundles that have strict mattress height limits. Simple, lightweight design is easy to lift and handle.
- Cons: Lacks significant cushioning and support for most sleepers. The under-4" thickness will feel very firm and may result in feeling the bed slats underneath. Not typically recommended for long-term daily sleeping.
The Agotnes is for situations where a very thin mattress is a necessity, particularly for safety and fit in bunk and trundle bed frames.

Asvang vs. Agotnes Comparison
Thickness & Feel
The most significant difference is the thickness. The Asvang is almost an inch thicker at 4 ¾", which provides slightly more cushioning and body support than the 3 ⅞" Agotnes. While both are labeled "firm," the extra foam in the Asvang makes it a more viable option for general use.
The thin profile of the Agotnes is its main advantage and disadvantage. It’s perfect for beds needing a mattress under 4 inches, but for most people, it will likely be too thin for comfort and you may feel the support slats of your bed frame through it.
Materials & Construction
Both mattresses use a simple, solid polyurethane foam core. The primary difference above the foam is the cover. The Asvang features a white, quilted polyester cover, which gives it a more traditional mattress look and offers a slightly softer feel upon first touch.
The Agotnes, on the other hand, has a dark blue cover made of a simpler, non-woven polypropylene material. Both covers are removable and machine washable, a major plus for cleanliness, especially if used in kids' rooms.
Price & Value
The Asvang and Agotnes are often identically priced, placing them squarely in IKEA's most budget-friendly tier. Because of this, value comes down to need. For most buyers who don't have strict height limitations, the Asvang offers better value - you're getting nearly an extra inch of foam for the same price. This translates to slightly more comfort and durability over time. The Agotnes only presents a better value if its thin profile solves a specific need, such as fitting into a trundle bed where a thicker mattress wouldn't work.
Who Each One Works Best For
These are not all-purpose mattresses and should be chosen for specific situations. The Asvang is a great all-around budget mattress for children transitioning to their first "big kid" bed, an accent daybed in a home office, or a spare room that sees guests only a few nights a year. Its 4 ¾" depth is just enough for these light-use scenarios.
The Agotnes’s function is more specialized. It should almost exclusively be considered for bunk beds (where a low profile is a safety requirement to keep the occupant below the guard rail), trundle beds that need to slide under another bed, or camper/RV builds with minimal headroom.
Which One Should You Choose?
Both mattresses serve the ultra-budget market well, but they are built for different purposes.
Choose the Asvang if:
- You're buying a mattress for a child's bed or a daybed.
- You want a bit more cushioning and support than the absolute thinnest option available.
- The bed frame has no specific height restrictions.
- You're seeking the best overall value for an occasional-use guest mattress.
Choose the Agotnes if:
- You absolutely must have a mattress that is under 4 inches thick.
- It’s for a bunk bed, a pull-out trundle, or an RV/campervan bed.
- The mattress will be used very infrequently for sleeping.
- You want the lightest, easiest-to-handle mattress possible.
Frequently Asked Questions
What’s the main difference between the IKEA Asvang and Agotnes?
The primary difference is thickness. The Asvang is a 4 ¾" mattress, while the Agotnes is a 3 ⅞" mattress. This makes the Asvang slightly more comfortable for general use and the Agotnes better suited for bunk beds or trundles with height limits.
Are the Asvang and Agotnes mattresses good for adults?
For nightly use, neither mattress is generally sufficient for most adults. Their thin foam core lacks the support and pressure relief needed for sustained comfort and proper spinal alignment. They are best for children or occasional, short-term guest use.
Do I need a special foundation or box spring?
You don't need a box spring, as these mattresses are designed for IKEA bed frames. However, they must be used on a bed base with solid slats or closely spaced sprung slats for adequate support. A platform bed or a slatted base is ideal.
Do these mattresses smell when you unwrap them?
Yes, it's common for both the Asvang and Agotnes to have a chemical odor after being unsealed, a process known as off-gassing. This is normal for compressed foam mattresses and the smell should dissipate within 72 hours in a well-ventilated room.
How long does it take for these mattresses to fully expand?
IKEA recommends allowing up to 72 hours for these roll-packed mattresses to fully expand and regain their proper shape and firmness. You can sleep on them sooner, but they will look and feel better after the full expansion period.
Which one is more durable?
Given they use similar foam, durability will be comparable and relatively low compared to more expensive mattresses. However, the slightly thicker foam in the Asvang may feel supportive for marginally longer under similar use compared to the thinner Agotnes.
Which mattress is firmer?
Both are rated as "firm" by IKEA. Due to its reduced thickness, the Agotnes may feel even firmer, as there is less material to compress between the sleeper and the bed slats.
Are the covers on the Asvang and Agotnes removable and washable?
Yes, both mattresses feature zippered covers that can be removed and are machine washable, which is a significant advantage for maintaining hygiene, especially in a child's bedroom.
