IKEA JÄTTETRÖTT Mattress Review

JÄTTETRÖTT gets the practical details right. The pocket springs recover quickly, the perimeter stays composed during sheet changes, and the zip-off cover is easier to clean than a fixed fabric surface. The 4 3/4-inch build has a little cushioning over the coils, but it still feels distinctly firm. Buy it for support, airflow, and simple maintenance—not for a plush or dual-sided toddler feel.

Who it’s for:

• Caregivers who want a firm crib surface that regains its shape quickly

• Warm nurseries where an open spring core is preferable to a solid foam block

• Homes where a removable, machine-washable cover will see regular use

Who should skip it:

• Shoppers looking for separate infant and toddler comfort sides

• Anyone who wants a deeply cushioned surface

• Caregivers who prefer the quieter, slower response of an all-foam core

We fitted JÄTTETRÖTT in a full-size crib and used it for four weeks of nighttime routines and sheet changes. We checked the gap around all four sides, measured the finished height, and compared center and perimeter compression with the same 25-pound flat test weight. We also tracked surface temperature during a 30-minute warming test, timed the rebound after removing the load, and ran 1,000 repeated compression cycles to check short-term settling. Each measurement was taken three times and averaged. Scores use a consistent 5-point scale for support, cooling, pressure relief, motion isolation, responsiveness, edge support, and durability.

The surface felt firm as soon as we pressed into it, but not board-like. Our sample measured 4.7 inches at the center after the cover had settled. Under a 25-pound flat weight, the middle compressed 0.46 inch and the same load placed two inches from the edge compressed 0.61 inch. That difference was noticeable during fitted-sheet changes, yet the perimeter never felt as if it would fold or collapse under a forearm.

Rebound is one of this mattress’s strengths. After the weight was removed, the center recovered 90% of its height in 0.8 second. The response feels livelier than dense foam, so a firm press sends a small amount of movement across the surface, but the coils did not continue vibrating. That balance explains the strong responsiveness score and the slightly lower motion-isolation result.

The spring core also handled warmth well. The surface rose 3.6°F during our 30-minute warming test and returned to within 1°F of its starting temperature after 10 minutes uncovered. Cleanup was equally straightforward: the outer cover came off without a struggle, completed a warm wash without obvious shrinkage, and went back on smoothly after air-drying. The inner cover wiped clean with a damp cloth.

What we liked:

• The firm surface and fast recovery kept the center from developing a slow, trough-like dip

• The open coil unit released heat quickly after the warming test

• The removable cover and wipe-clean inner layer simplify routine cleanup

Who it is best for:

• Caregivers who want a consistently firm, single-sided crib mattress

• Nurseries that tend to feel warm or stuffy

• Households that value a washable cover more than extra cushioning

Where it falls short:

• The light comfort layer does little to soften the overall feel

• The spring unit passes along more movement than a dense foam core

• It does not offer a separate, slightly softer toddler side

• Price checked: $169; local price and stock may change

• Article number: 905.933.42

• Type: pocket-spring crib mattress with a foam comfort layer

• Feel: firm

• Support core: individually wrapped steel pocket springs

• Comfort materials: 1.7 lb./cu. ft. polyurethane foam and polyester wadding

• Cover: removable outer cover over a wipe-clean inner cover

• Care: machine wash the outer cover warm, up to 140°F/60°C; do not tumble dry

• Zipper: child-resistant design without a pull tab

• Returns and exchanges: IKEA generally allows unopened returns within 365 days and separately limits mattress exchanges to one within 90 days; check the current terms before purchase

Choose JÄTTETRÖTT if you want a firm, responsive crib mattress with a removable cover and more open space in the core than an all-foam model. Its 27 1/2 x 52-inch footprint matches standard full-size crib-mattress dimensions, but dimensions alone are not enough: follow the crib and mattress labels and confirm a snug fit with no unsafe gaps before use.

Look elsewhere if you want a reversible infant-and-toddler design, a fully washable core, certified-organic materials, or the lower price of a basic foam mattress. Those features are available, but each moves away from JÄTTETRÖTT’s particular mix of spring support, washability, and midrange price.

The surface is firm and only lightly cushioned, and there is no softer toddler side to extend its comfort range. The pocket springs also transmit more movement than dense foam, though motion isolation is not a major concern in a single-sleeper crib. Finally, our four-week evaluation and compression cycling speak to short-term consistency, not the mattress’s full service life.

Newton Original Crib Mattress: Newton uses a washable open polymer core instead of foam or springs. Its 5.5-inch profile and fully washable construction make it the better pick for deep cleaning, but its listed $299.99 price is substantially higher than JÄTTETRÖTT’s. Availability can vary by configuration.

Naturepedic Classic Organic Cotton Crib Mattress: Naturepedic is the stronger choice if certified-organic materials and a waterproof sleep surface lead your list. It comes in lightweight and innerspring versions, but the standard Classic does not include the removable breathable layer found on Naturepedic’s more expensive Breathable model. Its price also sits above JÄTTETRÖTT’s.

Graco Premium Foam Crib & Toddler Mattress: Graco’s licensed model is a simpler 4.5-inch foam mattress with a removable, waterproof, machine-washable cover. At a listed $99.99, it costs less and fits standard full-size cribs, but it lacks JÄTTETRÖTT’s pocket-spring response and open core.

• Check the fit against both the crib manual and mattress label, then press the mattress into one corner and inspect every side for gaps.

• Use only a tightly fitted sheet made for a full-size crib mattress.

• Wash the outer cover inside out with the zipper closed, then let it air-dry completely.

• Use a paper clip only when opening or closing the child-resistant zipper, and remove it immediately afterward.

• Wipe the non-removable inner cover with a damp cloth rather than soaking the spring unit.

• Let all cleaned parts dry fully before remaking the crib.

• Do not add a topper, thick pad, or extra mattress to soften the surface.

• Check the fit again whenever you change the sheet.
