The OraCool King Mattress 5FT is a 26cm hybrid: 720 individually wrapped pocket springs arranged in seven zones, 1cm of Blue Air memory foam, a contoured comfort layer and a quilted knit cover, listed at £199.99. It takes ninth place in this guide, and its own specification sheet is the reason it sits here rather than higher. The field the listing labels "Item Thickness" reads "26 Picometre". The field directly below it, "Item Dimensions", reads 200 x 150 x 26 centimetres. A picometre is one trillionth of a metre, so one of those two figures is not a measurement anyone can buy a bed for. The bullet points say 26cm, the material description says a 22cm pocket-spring core under roughly 3cm of foam, and 26cm is 10.2 inches — the thickness one of the reviews quotes.

The rest of the sheet holds together better. The coil count is 720 in the title, in the first bullet and in the "Number of Mattress Coils" field; the seven layers in the bullets match the "Number of Layers" field; and the metric dimensions of 2L x 1.5W x 0.26Th metres convert to the same 200 x 150 x 26 centimetres. Two smaller oddities are worth knowing before you compare: the care instruction says "Hand Wash Only", and the rating breakdown supplied with this listing totals 100 ratings — 6 three-star, 13 four-star and 81 five-star — against the 37 ratings shown on the product page. Everything on this page comes from the Amazon listing for this mattress. We have not slept on it, measured it or tested it ourselves.

## Questions people ask

**How thick is the OraCool King Mattress?**

The listing gives two answers. The "Item Dimensions" field says 200 x 150 x 26 centimetres and the bullet points describe a 26cm mattress, but the separate "Item Thickness" field says "26 Picometre". The centimetre figure appears in three places; the picometre figure appears in one.

**How many springs does the OraCool King Mattress have?**

720 individually wrapped pocket springs in seven targeted support zones, according to the title, the first bullet point and the "Number of Mattress Coils" field, which all agree.

**How firm is it?**

The "Item Firmness Description" field says Medium, while the bullet points describe a "balanced medium-firm" sleeping surface suitable for back, side and combination sleepers.

**How is the OraCool King Mattress delivered?**

Vacuum-compressed and rolled, weighing 33kg, in a cardboard box. The listing says to allow 24 to 72 hours for it to expand fully. One review describes the double size as heavier but still manageable to move into place before opening.

**What warranty comes with it?**

The listing states a 100-night sleep test, a 5-year warranty and OEKO-TEX-certified materials.

**Do the reviews cover the size sold here?**

Not all of them. The listing is a King 5FT, but the reviews mention a 3FT single and a double, so some were written about other sizes in the same range.
