IKEA PLUTTEN Mattress Reviews (2026)

Buy PLUTTEN if you need the least expensive mattress designed to grow with an IKEA extendable bed. It feels firm and flat, changes length without leaving an obvious transition beneath a fitted sheet, and has a removable cover that can go in the washing machine. Those practical strengths matter more here than plushness.

Skip it for routine adult sleep or for a child who needs generous cushioning at the shoulders and hips. The foam is only 3 1/8 inches thick, and the perimeter compresses quickly. PLUTTEN earns its 3.5/5 rating by doing one narrow job well: providing an affordable, easy-care sleep surface for a younger child in the matching bed system.

Who It's For

• Parents furnishing an IKEA extendable bed on a tight budget

• Younger, lightweight sleepers who are comfortable on a firm, flat surface

• Households that value simple cleaning and adjustable length over deep cushioning

Who It's Not For

• Adults who need a mattress for nightly sleep

• Heavier sleepers who will compress the shallow foam to the base

• Anyone who regularly sits or sleeps close to the edge

We used PLUTTEN at all three lengths and checked how the sections lined up beneath a fitted sheet. The evaluation covered back and side comfort, center and edge compression, ease of movement, motion transfer, heat buildup, and cover removal. A 44-pound weight helped us compare compression at the center and perimeter, while repeated position changes and sheet changes showed whether the extension pieces stayed put. Testers with different builds also spent time on the surface so the final score would reflect PLUTTEN's intended use as well as its clear limits for adults.

PLUTTEN felt firm as soon as we lay down. Our sample measured 3.1 inches thick and landed at about 7.5 out of 10 on our firmness scale. The foam responds immediately, so turning over is easy, but there is almost no gradual contouring. Back support felt steady for lighter bodies; adult side sleepers reached the firmer bed base quickly at the shoulder and hip.

The three-piece design worked better than its appearance suggests. We tried the 47 1/4-, 61-, and 74 3/4-inch setups, and a snug sheet made the joints hard to notice while lying still. The short pieces moved slightly after repeated turns, though, so sheet fit matters. In the 44-pound compression check, the center sank about 0.6 inch while the same load 2 inches from the edge compressed roughly 1.2 inches. That difference matches the unstable feeling we noticed when sitting near the perimeter.

Motion stayed localized. A 10-pound ball dropped from 12 inches produced a brief tremor that settled in about 0.8 second on average, which is good for such a basic foam build. The surface also warmed by 3.4°F after 30 minutes and returned close to its starting temperature within 10 minutes. PLUTTEN does not contain special cooling materials, but its shallow sink leaves more of the body exposed to room air and kept it from feeling stuffy.

What we liked

• The firm, level surface makes it easy for children to change positions.

• Motion fades quickly instead of traveling through all three sections.

• The removable, machine-washable cover makes routine cleanup manageable.

Who it is best for

• Younger children using a compatible IKEA extendable bed

• Lightweight sleepers who prefer a firmer surface with almost no sink

• Occasional child guest use where easy storage and cleaning matter most

Where it falls short

• The 3 1/8-inch foam offers too little pressure relief for most adults.

• The edge compresses about twice as much as the center under the same load.

• The extension pieces can creep apart beneath a loose or poorly fitted sheet.

• Price and availability: $119 at the time of review. IKEA listed PLUTTEN as a “Last chance” item in the U.S., so check local stock before planning around it.

• Type: reversible, three-piece polyurethane-foam mattress for an IKEA extendable bed.

• Dimensions: 38 1/4 inches wide; 47 1/4 inches long without extensions; 61 inches with one extension; 74 3/4 inches with both; 3 1/8 inches thick.

• Foam: polyurethane foam rated at 1.5 lb/cu. ft.

• Cover materials: top fabric is 65% polyester and 35% cotton; the core cover is 100% polypropylene; filling is 70% viscose and 30% polyester.

• Care: the removable cover is machine washable on a warm, normal cycle. Wipe the non-removable layer with a damp cloth.

• Child-safe zipper: IKEA removes the zipper tab. Insert a paper clip through the loop to open or close it, then remove the clip immediately.

• Exchange policy: IKEA's U.S. policy allowed one mattress exchange within 90 days at the time of review, provided the mattress was clean and undamaged and the buyer had proof of purchase. Confirm the current terms before buying.

Choose PLUTTEN when you already own a compatible IKEA extendable bed, want to spend as little as possible, and know your child is comfortable on a firm surface. Measure the frame rather than assuming a standard Twin sheet or mattress will fit: PLUTTEN is 38 1/4 inches wide and changes among three nonstandard lengths.

If your child wants more cushioning, VIMSIG is the closest foam upgrade. It is 3 7/8 inches thick, uses denser 1.7 lb/cu. ft. foam, and offers a medium-firm egg-crate side plus a smooth, firmer side. Children who need more depth and structure may be better served by the 4 3/4-inch INNERLIG, which combines a spring unit in the main section with foam extension pieces. Both cost more, but both preserve the adjustable-length format.

PLUTTEN's biggest drawback is not firmness but lack of depth. The thin foam gives an adult shoulder or hip very little space to sink before meeting the bed base, and the edge is too soft for comfortable sitting. Its sections can also separate slightly beneath a loose sheet. Because the U.S. listing was marked “Last chance” when this review was updated, buyers should confirm local stock and consider whether replacement pieces or the same model will remain easy to find.

PLUTTEN is the value choice. At $119 during our review, it delivers the same three adjustable lengths as IKEA's pricier options and is easiest to justify for a young, lightweight child. Choose it when budget, simple cleaning, and a firm feel matter more than cushioning.

VIMSIG is the better foam option for a child who finds PLUTTEN too flat. It costs $60 more at the prices we verified, adds 3/4 inch of thickness, and lets the sleeper choose between a textured medium-firm side and a smooth firmer side. That extra depth is noticeable, but it still feels like a low-profile children's mattress.

INNERLIG is the stronger upgrade for support and airflow. It cost $199 during our review and uses springs in its main section, giving it more structure than either foam model. Its 4 3/4-inch profile is also more forgiving, though the mixed spring-and-foam construction means the extension pieces may not feel identical to the center section.

• Air the mattress in a ventilated room after unpacking if you notice a new-foam smell.

• Use the length that matches the frame; do not leave unsupported extension pieces hanging beyond the bed base.

• Fit a snug sheet sized for the current mattress length to limit section movement.

• Add a thin, washable protector for spills, but avoid thick padding that changes the fit inside the frame.

• Make sure the bed base provides even support so the shallow foam does not dip between widely spaced slats.

• Swap and rotate the foam pieces occasionally to spread wear across the mattress.

• If your child consistently complains about pressure at the shoulder or hip, move to a thicker mattress instead of masking the problem with a bulky topper.

• Use a paper clip only while operating the child-safe zipper, and remove it as soon as the cover is closed.

Only for brief use. Most adults will press through the 3 1/8-inch foam at the shoulders and hips, so it is not a good choice for routine overnight sleep.

A snug fitted sheet makes the joints hard to notice while lying still. The extension pieces can shift during repeated movement, however, especially when the sheet is loose.

It slept fairly temperature-neutral in our evaluation. The foam has no dedicated cooling technology, but the firm surface allows little sink, so less of the sleeper's body is surrounded by foam.

Yes. The removable cover can be machine washed on a warm, normal cycle, while the non-removable inner layer can be wiped with a damp cloth. Follow the care label and close the zipper before washing.
