Six 14" pocket-spring hybrids with cooling gel memory foam Euro tops, fiberglass-free and delivered rolled in a box, in Twin to California King. Plus the Cloud modular sectional sofa.
Find Your Firmness
Slecofom makes 14" hybrid mattresses that combine individually pocketed coils with layered gel memory foam, and it sells them compressed in a box. The lineup is built around firmness. The black Euro Top series has three coil systems, from Medium Firm to Ultra Firm, while the original grey series adds Firm and Plush Firm options with extra lumbar support.
Across the six mattresses there are 25 size and firmness combinations, from a Twin Medium Firm to a California King Ultra Firm, each backed by a 10-year warranty. The Extra Firm Euro Top is the brand's most-reviewed mattress, at 4.4★ from 168 ratings. Slecofom also makes the Cloud Sectional, a 108" modular corduroy sofa that ships in two boxes.
Individually wrapped coils with heavier-gauge perimeter rows for firm, even support and less motion transfer.
Gel memory foam and open-cell airflow foam in a thick Euro top that softens the surface and releases heat.
CertiPUR-US foam, OEKO-TEX Standard 100 fabric and a fiberglass-free fire barrier meeting 16 CFR 1632 & 1633.
Ships vacuum-packed; unroll it on the frame and it reaches its full 14" in 48–72 hours.
Six firmness options in two series. Filter by bed size:
The black Slecofom series shares one 9-layer construction and changes only the coil system underneath. On top sits a multi-layer Euro top: a 480 GSM air-layer knit cover, a 16 CFR 1632 & 1633 fire barrier, 0.5" of cooling gel memory foam, 1.5" of 28D open-cell airflow foam and 2.5" of 38D support foam. Below it is an 8" pocket spring unit wrapped in 40D foam-encased edge support, on 1.5" of 38D high-density foam and a 460 GSM jacquard knit base. Medium Firm, Extra Firm and Ultra Firm each come in Twin, Full, Queen, King and California King.
The softest of the black Euro Top models: 2.10 mm pocket coils with a double row of 2.25 mm perimeter coils, under a thick cooling gel Euro top.
Best ratedThe best-rated Slecofom mattress: 2.15 mm pocket springs with three rows of 2.35 mm perimeter coils for a firm, flat support core under a soft Euro top.
The firmest build in the lineup: 2.20 mm pocket coils, three rows of 2.40 mm perimeter coils and an 8-layer stack rated for up to 1,150 lb.
The grey Slecofom series is the original line: gel memory foam comfort layers over individually pocketed coils, with a pillow-style Euro top, a skin-friendly grey knit cover and side handles. The Firm model lists a 0.5" cooling gel memory foam layer, 1" pressure-relief foam, 3" high-rebound support foam and a 9" edge-support pocket coil unit. Choose Medium Firm, Firm with extra lumbar support, or the upgraded Plush Firm with thicker coil wire.
The original Slecofom hybrid: gel memory foam over individually pocketed coils, with a pillow-style Euro top and a breathable grey knit cover.
A firmer grey-series hybrid: 9" pocket coil unit with 2.2 mm edge-support coils, 3" of high-rebound support foam and a cooling gel memory foam top.
The upgraded grey hybrid: thicker 2.1 mm / 2.3 mm support coil wire with extra lumbar support, finished with a plush cotton Euro top.
A two-piece L-shaped boneless couch in dark grey corduroy: high-resilience 35 kg/m³ foam with built-in independent springs, a 28" deep seat and two matching throw pillows. It ships vacuum-compressed in two boxes and needs no assembly.
Every black-series Slecofom mattress stacks a five-layer comfort zone — knit cover, fire barrier, cooling gel memory foam, open-cell airflow foam and support foam — over a four-layer support zone built around an 8" pocket spring unit and a foam-encased edge.
More than 4" of multi-layer Euro top softens the surface, while the coil gauge sets the firmness underneath. Each coil is individually pocketed, and the heavier-gauge perimeter coils keep the mattress level from the center to the edge.
A high-density reinforced foam frame wraps the whole coil unit, so the edge does not collapse when you sit on it or sleep near it. That widens the usable sleep surface and helps the mattress hold its shape over time.
The layered foam top contours around the shoulders and hips while the coils underneath keep the spine aligned. The firmer models suit back and stomach sleepers who want less sink; Medium Firm gives side sleepers more give.
The grey hybrids pair a cooling gel memory foam top and pressure-relief foam with high-rebound support foam and a pocket coil unit with reinforced edge coils, finished with a breathable 3D side fabric and handles for rotating the mattress.
The Cloud Sectional is two independent modules, so it works as an L-shaped sofa, a lounger or a floor-level bed for guests. The corduroy covers come off, and the high-resilience foam springs back into shape after use.

From the box to the first night, based on the Slecofom listing instructions.
Carry the box to the bedroom before opening it and set the rolled mattress at the foot of the bed frame.
Unroll the mattress along the frame with the Euro top facing up, still inside its inner plastic.
Cut the plastic carefully, keeping blades away from the cover, and remove every layer so the foam can draw in air.
Leave it for 48–72 hours at room temperature to reach full height. It can be slept on sooner, but the final feel settles after full expansion.
Once it reaches 14", use deep-pocket fitted sheets sized for a 14" mattress.
Six 14" hybrid mattresses in two series. The black Euro Top series comes in Medium Firm, Extra Firm and Ultra Firm, each in Twin, Full, Queen, King and California King. The grey series comes in Medium Firm, Firm with extra lumbar support and Plush Firm, in Twin to King depending on the model.
The Ultra Firm. It uses 2.20 mm pocket coils with three rows of 2.40 mm perimeter coils and is rated for up to 1,150 lb. The Extra Firm is one step softer with 2.15 mm / 2.35 mm coils, and the Medium Firm uses 2.10 mm / 2.25 mm coils.

The black series has a black knit cover, a thicker multi-layer Euro top, an 8" pocket spring unit and a 40D foam-encased edge, and comes in five sizes including California King.
