Layer Details
- Stretch Knit Fabric Cover. A soft, pliable cover that lets the fillings beneath contour to your body shape. In practice this means you feel the comfort layers working rather than a taut, drum-like surface.
- White Fibre Fillings. A lightweight, high-loft filling that retains its shape and is hypo-allergenic. It adds a layer of cushioning between you and the foam core, and should resist flattening over time.
- Advanced Reflex Foam Core. A supportive, long-lasting hypo-allergenic foam that conforms to your body by distributing weight evenly, which means reduced pressure points at the usual sore spots. This is the main support layer, as the Hudson contains no springs.

- A sensible depth for bunks and mid sleepers: At 18cm the Hudson sits low enough for many raised frames with safety rails, where a taller mattress would leave too little rail above the sleeper.
- Light enough for awkward stairs: A single-width foam mattress with no springs is one of the easiest sizes to carry up to a loft room or into a student flat.
- Flippable, which matters for growing sleepers: It's double-sided, so a child or teen who sleeps in the same spot every night can have it flipped and rotated to even out wear.
- Hypo-allergenic fillings for a child's room: The white fibre fillings and foam core are hypo-allergenic, a reassurance if you're kitting out a bedroom for a dust-sensitive sleeper.
- Fits the tightest rooms: At 90cm wide it leaves floor space for a desk, wardrobe or toy storage, and we suggest a room of at least 2.1m x 2.8m.
This size suits you if...
You're furnishing a child's or teenager's room and want a flippable, allergy-friendly mattress that won't sit too tall on a cabin or bunk frame, you need a spare bed for a room that spends most of its week as an office, or you're a solo adult in a compact room, student let or first flat where the frame came with the tenancy and the mattress didn't.
Consider another size if...
You're an adult who tends to sprawl, or you simply want more room to turn over at night. The UK small double is 30cm wider at the same length, and we'd recommend it if your room allows.

Will the Highgrove Hudson UK single fit a bunk bed or mid sleeper?
It's a strong candidate. Bunk and mid-sleeper frames usually specify a maximum mattress depth so the safety rail still sits well above the sleeper, and at 18cm the Hudson is slimmer than many boxed mattresses. Check your frame's stated maximum before ordering, but this is one of the easier foam mattresses to pair with a raised bed.
Is the Highgrove Hudson single a good mattress for a child or teenager?
It suits that job well. The medium foam feel works across sleeping positions, the fillings are hypo-allergenic, and because it's double-sided you can flip it to spread the wear a growing sleeper puts into one spot. Lighter side sleepers may find it slightly firm at the shoulder, so a very slight teen who sleeps on their side should try before committing.
What size room do I need for a UK single mattress?
We suggest allowing at least 2.1m x 2.8m of floor space. That leaves room to walk alongside the bed and open drawers or a wardrobe. At 90 x 190cm the UK single is the most forgiving standard size, so it also works under a loft conversion slope or in a shared children's room where two beds need a walkway between them.
How much smaller is a UK single than a UK double?
The UK single is 45cm narrower than the UK double, and the two are the same length at 190cm. That extra width is the difference between a one-person bed and one two people can share, so if the Hudson is for a couple, the UK double is the right starting point rather than the UK single.
Where can I buy the Highgrove Hudson in a UK single?
Compare the retailers listed on this page. The prices shown here are updated as retailers change them, so it's worth checking back rather than assuming the figure you saw last week still stands. Availability in individual sizes shifts too, which is another reason to rely on the live table rather than a stockist you remember.
