What Grbsy makes

Grbsy is a mattress-in-a-box brand that sells through Amazon. Its US range splits into two families. Hybrids pair gel memory foam with 1,000+ individually pocketed coils arranged in seven support zones. All-foam models use HEXACELL dynamic memory foam under an ice-silk cooling cover. Every mattress ships vacuum-rolled, and the listings state CertiPUR-US foam, OEKO-TEX textiles and a fiberglass-free build. This page gathers the models that are currently in stock, with their real sizes, layers and Amazon ratings.

What every Grbsy mattress shares

These points are the same across the whole US range.

Seven-zone support

Firmer under the hips and lumbar, softer at the shoulders, built into either the coil grid or the foam.

Cooling materials

Graphene-infused or ice-silk covers, gel memory foam and open-cell foam channels move heat away.

Certified, fiberglass-free

CertiPUR-US foam, OEKO-TEX Standard 100 textiles and the CFR 1633 flammability standard, with no fiberglass.

Ships in a box

Vacuum-rolled into a compact box that fits through hallways, elevators and narrow stairs.

Grbsy videos

Short product videos from Grbsy, filmed for these exact models.

Unboxing and setup

The steps Grbsy gives for its rolled mattresses and toppers, in order.

Carry the box in first

Take the box to the bedroom before opening it. A rolled mattress is much easier to move than an expanded one.

Unroll on the base

Lay the roll on your bed frame, slats or platform, and position it before you cut anything.

Remove the wrapping

Cut the outer film carefully, working away from the fabric, and pull off the vacuum layer.

Give it time to expand

Mattresses need a few hours before you sleep on them. Toppers need 48–72 hours to reach full thickness.

Air the room

New foam can smell faintly at first. An open window helps it clear over the first days.

Zoned models have a head end and a foot end, so keep the firmer lumbar zone under your hips. If you rotate the mattress, turn it back again. A waterproof protector keeps the fixed covers on the hybrids clean.

Grbsy mattress FAQ

Where are Grbsy mattresses sold?

In the US, Grbsy sells through its Amazon storefront. The mattresses and toppers ship directly from the brand's Amazon sellers, and Grbsy.shop links to those listings.

What's the difference between the Grbsy hybrids and the memory foam models?

The hybrids (PrimeNest, EcoNest, 7-Zone Hybrid and the 16″ Luxury Hybrid) put foam comfort layers over 1,000+ individually pocketed coils. That gives more bounce, airflow and edge support. The NightAir and Firm Gel models are all-foam, with a more enveloping, motion-quiet feel.

Which Grbsy mattress is the firmest?

The Firm Gel Memory Foam model, which Grbsy rates 7.5 out of 10. The hybrids are all medium firm. To make an existing bed firmer, the two extra-firm toppers use 45D high-density foam.

Does Grbsy make RV mattresses?

Yes. The PrimeNest and EcoNest hybrids both come in RV Short Queen (60″ × 75″), in 12″ and 14″ profiles. Check your camper's platform depth before choosing the taller one.

Which Grbsy mattress is best for hot sleepers?

NightAir pairs an ice-silk, graphene-infused cover with open-cell HEXACELL foam and gel layers. Among the hybrids, PrimeNest and the 16″ Luxury Hybrid use graphene covers, and the coil core itself lets air move.

What trial and warranty come with Grbsy mattresses?

Most Grbsy mattress listings state a 365-night home trial and a 10-year warranty. The Firm Gel model states 180 nights. The toppers come with 180-night (egg-crate) or 120-night (4″ cooling) trials. The terms on the Amazon listing apply.

How long does a Grbsy mattress take to expand?

Grbsy says the mattresses are ready to sleep on after a few hours. Toppers need 48–72 hours to reach full thickness. Keep the room warm and ventilated for the fastest recovery.

Are Grbsy mattresses fiberglass-free?

Yes. The listings state fiberglass-free construction, CertiPUR-US certified foam, OEKO-TEX Standard 100 textiles and compliance with the US CFR 1633 flammability standard.

Should I pick 12″, 14″ or 16″?

Taller profiles add comfort foam. The 12″ is the firmest-feeling and suits RV platforms and bunk beds. The 14″ is the everyday choice. The 16″ gives the deepest cushioning and a high, hotel-style look.

Can I wash the cover?

The NightAir memory foam mattress and both toppers have zip-off, machine-washable covers. The hybrid listings don't describe a removable cover, so use a mattress protector on those.
