## At a glance

- The listing describes a two-layer, all-foam build with a 4 cm gel memory foam layer and 16 cm high-density foam support layer.
- The cover is described as removable and machine washable. The care instruction applies to the cover.
- The seller says the mattress arrives vacuum-sealed and compressed, and should be allowed 48–72 hours to expand after opening.

## Pros

- The medium firmness and single-bed dimensions are clearly stated for buyers matching a 3FT frame.
- The two foam layers offer a distinct comfort layer over high-density foam support, rather than a spring construction.
- A removable, machine-washable cover can make routine cover care easier.

## Cons

- This is an all-foam mattress, so it is not a spring or hybrid option.

## Before you buy

- Listing details conflict or remain unconfirmed: the title and size give 90x190x20cm, while the dimensions field lists 190 x 90 x 20 centimetres. Construction is called both Gel Foam and memory foam with a gel memory foam comfort layer. A nominal washable-cover feature is not corroborated by the explicit contents list, which names only a manual. Confirm the selected listing and package details before buying. The listing also says to allow 48–72 hours for expansion after unboxing.

## In the box

- Manual (Included)
- Washable cover (Check selected pack): A washable-cover feature is claimed, but the explicit contents list names only a manual. Check the selected listing.

## A good fit for

- Shoppers needing a medium 3FT single mattress with a listed 20 cm thickness.
- Buyers who prefer a foam mattress with a gel memory foam comfort layer and high-density support layer.
- People who value a removable cover and are prepared to follow its machine-wash care instruction.

## Less suited to

- Anyone specifically seeking a sprung or hybrid mattress.
- Buyers who need a foldable or portable mattress.

## Customer feedback

Customer feedback reports comfort, a preferred balance of firmness and softness, support and better sleep quality, with some customers mentioning reduced body aches. These impressions may matter to buyers considering the listed medium firmness and foam layers, but sinking experiences are mixed, so feel and support may not suit everyone.
- Positive themes: Customer feedback highlights comfort, firmness, support and sleep quality.
- Mixed feedback: Feedback on sinking is mixed.

## Frequently asked questions

### What size is this mattress?
It is listed as a 3FT single, with a stated size of 90x190x20cm. The separate dimensions field reverses the length and width order, so confirm the size against your bed frame.
