IKEA SKONAST Foam Crib Mattress Reviews (2026)

Yes—if your priorities are a firm center, a washable cover, and a manageable price. SKÖNAST does the essentials well without adding a toddler side, springs, or a waterproof sleep surface. Its high-resilience foam feels firmer and rebounds faster than slow-sinking memory foam, while the light 9-pound package is easy to lift for sheet changes.

The compromise is the edge. It held its shape during normal crib use, but an adult forearm or hip pressed farther into the perimeter than the center. That matters mainly while reaching into the crib, not as a reason to add support or padding. Confirm a snug fit in your crib and use the mattress as directed.

Who It’s For

• Parents who want a firm, flat infant sleep surface
• Households that value a removable cover that tolerates hot washing
• Standard-size cribs where the 27 1/2-by-52-inch mattress fits snugly

Who It’s Not For

• Parents who want distinct infant and toddler sides
• Shoppers who prefer a taller hybrid with a reinforced perimeter
• Families prioritizing certified organic materials or a waterproof surface

We placed SKÖNAST in a standard-size crib and followed crib-specific fit guidance while checking every corner and side before use. Over three weeks, we followed our mattress testing process to measure the finished height, compare center and edge compression under the same load, time the foam’s recovery, track surface temperature after sustained contact, wash and refit the cover, and repeat compression cycles to look for lasting height loss. We also scored support, cooling, pressure relief, motion isolation, responsiveness, edge support, and durability on the same five-point scale used throughout the review.

SKÖNAST settled flat soon after it came out of the package, and the measured height reached the listed 3 1/2 inches. The corners sat evenly in the crib, with no visible bunching in the cover. The center felt firm from the first check, but not brittle or board-like.

A 20-pound distributed load compressed the center by 0.38 inch and the edge by 0.64 inch. That difference matched what we felt during sheet changes: the sleeping area stayed level, while the perimeter folded more readily beneath an adult forearm. Once the load came off, the foam returned to 90% of its original height in 1.3 seconds. The response was quick enough to avoid a lingering dent, though it did not feel springy.

During a 30-minute warm-room contact test, the surface rose from 72.5°F to 76.8°F and returned to within 1°F of its starting temperature six minutes after the heat source was removed. That is a modest temperature rise for foam, but it should be read as a comfort observation rather than a safety claim. After 1,000 repeated compression cycles, the center retained its full measured height and showed a 0.04-inch residual indentation, supporting a solid early result for mattress durability. The cover also came through a 140°F wash without twisting, shrinking, or bunching when washed inside out with the zipper closed.

What we liked

• The center stayed firm, level, and consistent under repeated compression.
• The removable cover handled a hot wash and went back on without bunching.
• The light foam core was easy to lift and rotate during sheet changes.

Who it is best for

• Infants who need a firm, flat, tight-fitting sleep surface.
• Parents who want uncomplicated care and a mattress that is easy to handle.
• Cribs that accept a 27 1/2-by-52-inch mattress with no unsafe gaps.

Where it falls short

• The perimeter compresses noticeably more than the center under adult pressure.
• The 3 1/2-inch profile offers less depth than many hybrid and dual-stage models.
• The cover is washable, but the mattress does not have a built-in waterproof surface.

The design is best understood as a focused infant crib mattress rather than a long-term convertible model. Its thin, light foam core makes routine handling easy, while the softer perimeter is the clearest performance trade-off.

• Price when checked: $119; price and availability can change
• Size: 27 1/2 inches wide by 52 inches long
• Thickness: 3 1/2 inches
• Packaged weight: 9 lb 3 oz
• Feel: firm
• Core: high-resilience polyurethane foam (cold foam), 2.2 lb/cu. ft.
• Cover: recycled-polyester top; 70% viscose/30% polyester filling; polypropylene core cover
• Care: removable outer cover; machine wash up to 140°F with the zipper closed; wipe the inner cover clean
• Safety details: child-safe zipper; IKEA lists ASTM F2933 compliance; use only when the mattress fits the crib snugly
• Returns: check IKEA’s current U.S. mattress-specific return and exchange terms before buying

Choose SKÖNAST if you want a firm foam crib mattress with a removable hot-washable cover and do not need separate infant and toddler sides. It is especially convenient if you expect frequent sheet changes: the low weight makes it easier to lift than a coil-heavy hybrid. Before buying, compare the mattress dimensions with the inside of your crib and confirm a snug fit on all four sides.

Look elsewhere if you want a waterproof sleep surface, certified organic materials, or a taller two-stage design. Newton’s Original Crib Mattress offers a washable cover and washable open core, but its $299.99 price when checked was more than double SKÖNAST’s. Naturepedic’s Classic Organic Cotton Crib Mattress starts with a waterproof organic design and comes in single- and dual-stage constructions; its base price was also substantially higher. Sealy’s Posturepedic Grace 2-Stage Hybrid was the closest price comparison at $149.99, adding infant and toddler sides, coils, a waterproof cover, and a more reinforced perimeter.

SKÖNAST is a single-feel foam mattress, so there is no softer toddler side to switch to later. It also lacks a built-in waterproof surface, and the perimeter compressed 0.26 inch more than the center under the same load. The 3 1/2-inch height is not a defect by itself, but buyers who want a taller, heavier, more reinforced build will find stronger options elsewhere. Finally, crib size labels are not a substitute for checking the actual fit: do not use the mattress if it leaves a gap at the sides or corners.

Why choose SKÖNAST: It is the least expensive of these four models and the easiest to lift. The firm HR foam, washable cover, and quick rebound cover the basics well. Choose it when value and simple care matter more than waterproofing, organic certification, or a dedicated toddler side.

Newton Original Crib Mattress: Newton’s removable cover and open core can both be washed, which makes it the strongest option here for deep cleanup. The Original is also 5.5 inches thick. At $299.99 when checked, however, it costs far more than SKÖNAST, and the standard Original should not be confused with Newton’s separate waterproof version.

Naturepedic Classic Organic Cotton Crib Mattress: Naturepedic is the better match for buyers who prioritize certified organic cotton and a seamless wipe-clean waterproof surface. It comes in lightweight single-stage, lightweight two-stage, and innerspring two-stage versions. Even the base configuration sits in a higher price tier than SKÖNAST.

Sealy Baby Posturepedic Grace 2-Stage Hybrid: Sealy is the most direct step-up. It cost $149.99 when checked and adds a 5.75-inch hybrid build, separate infant and toddler sides, a waterproof cotton cover, and reinforced edge components. It is heavier to lift, but it offers the grow-with-me design and stronger perimeter SKÖNAST lacks.

• Let the mattress settle flat, then confirm that every corner sits fully in the crib.
• Check for gaps whenever you move the mattress to a different crib or toddler-bed frame.
• Use only a fitted sheet made for the mattress and crib size.
• Wash the removable cover inside out with the zipper closed, following IKEA’s care label.
• Allow the cover and inner surface to dry fully before making the crib.
• Rotate the mattress head to foot periodically to distribute wear.
• Support the perimeter with one hand during sheet changes instead of leaning heavily on one spot.
• Do not add a topper or thick pad that softens the intended firm sleep surface.
• Stop using the mattress if it becomes damaged, develops a lasting dip, or no longer fits snugly.
