Assessed from Bodyshape's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
If you want firm orthopaedic-style support without a big spend, this is a sensible shortlist candidate. The reflex foam base is durable and holds its shape over time, which means the mattress should resist sagging better than cheaper all-foam builds, while the 3cm of memory foam moulds to your body to ease pressure on hips and shoulders. Yes, at 20cm deep it's slimmer than many premium mattresses, but that keeps the price down, and it's available in five UK sizes from Single to Super King. Delivery is free to most locations, with a two-hour time slot, next day weekday delivery and optional room-of-choice delivery for £20.00.
Key Features & what's inside
- Knitted cover. A soft knitted top that adds cosiness and warmth while allowing enhanced airflow. In practice, that means a gentler first touch without trapping quite as much heat as some foam mattress covers.
- Memory Foam. A 3cm comfort layer that adapts to the contours of your body and moulds to your shape, which means pressure points like hips and shoulders get some cushioning. It's a fairly slim layer, so the firm base makes itself felt through it.
- Reflex Foam. A 17cm supportive base that is durable and resilient, holding its shape over an extended period. This is where the firm feel comes from, and it should keep the mattress performing consistently for longer.

Who's it NOT for?
Lightweight side sleepers may find the firm feel puts pressure on shoulders and hips, as the 3cm memory foam layer is slim. If you like a deep, plush, sink-in surface, or a mattress with handles for easy repositioning, this isn't it. Hot sleepers should also note memory foam can retain some warmth.
Bodyshape Ortho Memory Foam Mattress
Across 348 reviews on the Mattress Online product page, rated 4.5, owners commonly report comfortable, supportive sleep and often an improvement in back pain, with material quality seen as good for the price. Some find it slightly thinner than expected and note the lack of handles makes repositioning awkward.
Is the Bodyshape Ortho memory foam mattress firm or soft?
It's firm. The 17cm reflex foam base provides a solid, supportive feel, with 3cm of memory foam on top adding some contouring. It suits back and front sleepers who want firm support, although lightweight side sleepers may find it a little too hard.
How deep is the Bodyshape Ortho mattress?
It's 20cm deep in total: a 3cm memory foam comfort layer over a 17cm reflex foam base, topped with a knitted cover. That's slimmer than many premium mattresses, and some owners note it feels slightly thinner than they expected, so check it suits your bed frame and fitted sheets.
Does the Bodyshape Ortho mattress come with a trial and guarantee?
Yes. It comes with a 100-night trial, so you can sleep on it at home before committing, plus a 3 year guarantee covering manufacturing faults.
What sizes does the Bodyshape Ortho mattress come in?
Five UK sizes: Single, Small Double, Double, King and Super King. Prices range from £199 to £349 depending on size.
Is the Bodyshape Ortho mattress good for back pain?
Owner reviews commonly mention an improvement in back pain, which fits its firm, supportive build. That said, everyone's back is different, and the 100-night trial gives you time to judge for yourself at home.
