What makes up the Cloudnest

The main points from the Amazon.co.uk listing.

Seven-zone springs

More stability under the lumbar and hips, with extra cushioning at the shoulders for a better sleeping posture.

Less partner disturbance

Each spring is encased and moves on its own, so turning over stays on one side of the bed.

Certified materials

CertiPUR-US certified foam and OEKO-TEX certified textiles, under an embossed fire-resistant top.

Rolled for delivery

Vacuum-packed and boxed, so it's easy to carry upstairs before it expands.

Unboxing and setup

How to get a rolled Grbsy mattress ready for its first night.

Carry the box in first

It's heavy (about 33–36 kg), so two people make it easier. Take it to the bedroom before you open it.

Unroll on the base

Lay the roll on your divan, slats or platform, grey side panels facing out, before you cut anything.

Remove the wrapping

Cut the outer film carefully, working away from the fabric, then peel off the vacuum layer.

Let it recover

Owners report it reaches full depth after around 72 hours. Leave it until then before judging the feel.

Air the room

Open a window for the first days while the new-foam smell fades.

The springs are zoned, so keep the head end at the head of the bed. The non-slip base helps it stay put on a divan or slatted frame.

Grbsy mattress FAQ (UK)

Where can I buy a Grbsy mattress in the UK?

Grbsy's UK Cloudnest mattress is sold on Amazon.co.uk. The links on this page open those listings directly.

What sizes does the Grbsy Cloudnest come in?

A Double (4ft6, 135 × 190 cm, about 30 cm deep) and a 5ft King (150 × 200 cm), which comes in 28 cm and 30 cm depths.

How firm is the Grbsy Cloudnest?

Grbsy lists it as medium firm. Most owners call it a good balance of firm and soft, while a few who prefer a softer bed describe it as very firm.

Is it a pocket sprung or a memory foam mattress?

Both. It's a hybrid, with individually pocketed springs in seven zones for support and a memory foam layer on top for comfort.

Will I feel my partner moving?

The pocket springs work independently and absorb movement locally, so a partner turning over or getting up is largely kept to their side.

How long does it take to expand?

It starts recovering as soon as it's unwrapped. Owners on Amazon.co.uk recommend allowing about 72 hours before judging the final depth and feel.

Is there a trial period and warranty?

The listing states a 120-night home trial and a 10-year warranty. The terms shown on Amazon.co.uk apply.

Is the Grbsy mattress fire-resistant?

The listing describes an embossed fire-resistant top, with CertiPUR-US certified foam and OEKO-TEX certified materials.

Can I sit on the edge?

The edge is softer than the centre. One owner noted you can't sit right on the edge, so the Cloudnest suits sleeping more than perching.

Does it fit a standard UK bed frame?

Yes. It's made in standard UK Double (135 × 190 cm) and King (150 × 200 cm) sizes, so it fits divans, slatted frames and platforms built to those sizes.
