The Harrison Spinks Levisham 3750's feel is medium to firm, so you get a supportive base softened by layers of Yorkshire wool, cotton, hemp and flax. It's 24cm deep and comes in five sizes from UK Single to UK Emperor. Yes, it needs regular turning, but the turning handles make that easier than you might expect, and rotating helps the natural fillings last. If you sleep hot, the breathable wool and hemp fillings should help you stay comfortable.

Why should you choose this mattress?
This mattress leans heavily on natural and recycled materials: Yorkshire wool for insulation, cotton to wick moisture, hemp for breathability, and an eco-polyester layer made from 100% recycled materials that can be recycled again. That combination means it regulates temperature well without relying on foam, a genuine plus if you tend to overheat at night. It's a National Bed Federation Approved Brand and handcrafted in the UK. It's a considered purchase, but the spring count and quality of fillings go some way to justifying it. Mattress Online lists a 100-night trial and a 5 year guarantee with this mattress, though those are the retailer's own terms rather than the manufacturer's.
Key features & layer details
Wool
Wool comfort fillings that stay cosy through the night, which means natural insulation in winter and temperature regulation in summer. It's the layer closest to you, so you feel its softness first.
Cotton
Natural cotton fibres that wick away moisture, which means a fresher, drier sleeping surface. Helpful if you run warm at night.
Hemp
An eco-friendly fibre that's naturally breathable and durable, adapting to different temperature conditions. It also acts as a natural insulator, adding to the mattress's temperature control.
Soft White Fibres
Soft synthetic fillings that add a cosy feel while staying resilient. This layer holds its shape over time, so the comfort shouldn't flatten quickly.
Eco-polyester
A supportive layer made from 100% recycled materials, and it can be recycled again at the end of its life. A quiet win if sustainability matters to you.
Pocket Springs
3750 Cortec Quad Core pocket springs, each encased in its own cloth pocket, which means each spring responds independently to your body. The design prioritises breathability and resilience.

Best suited for?
Warm sleepers
Breathable wool and hemp fillings, plus cotton that wicks away moisture, keep the surface fresher and drier, so you are less likely to overheat overnight.
Eco-conscious buyers
Yorkshire wool, cotton and hemp sit alongside an eco-polyester layer made from 100% recycled materials that can be recycled again, so sustainability runs through the build.
Back sleepers
A medium to firm feel with a supportive pocket spring base gives a steady, level surface, softened by the natural layers on top.
Couples
Each of the 3750 pocket springs sits in its own cloth pocket and responds independently, and the larger sizes up to UK Emperor give two people room.
Heavier sleepers
The medium to firm support from the Cortec Quad Core springs and a 24cm depth means you should sink in only so far.
The medium to firm feel may be a little too solid for lightweight side sleepers, who might not sink in enough to keep their spine aligned. If you want a maintenance-free mattress, look elsewhere: the natural fillings benefit from regular turning. Budget shoppers may also find the starting price a stretch.
Save on an earlier or ex-display model
Some retailers still sell the earlier version of this mattress, or ex-display and returned stock at a lower price. These are the sizes where it costs less than the current model's best price.

FAQ's
How firm is the Harrison Spinks Levisham 3750?
It's described as medium to firm on the retailer's product page. Owners describe a balanced feel: slightly soft when you first lie down, with firmer underlying support. That suits most back and combination sleepers, although lightweight side sleepers may find it a little too firm.
Does the Levisham 3750 come with a trial period?
Mattress Online lists a 100-night trial with this mattress. That's the retailer's own offer rather than a Harrison Spinks guarantee, so if you buy elsewhere, check that retailer's returns terms before ordering.
What is the Levisham 3750 made of?
The fillings are largely natural: Yorkshire wool, cotton, flax and hemp, plus soft white fibres and an eco-polyester layer made from 100% recycled materials. Support comes from 3750 Cortec Quad Core pocket springs. It's handcrafted in the UK and 24cm deep.
Is the Harrison Spinks Levisham 3750 good for hot sleepers?
It should be. The wool, cotton and hemp layers are naturally breathable and temperature regulating, and the cotton wicks away moisture. The pocket springs are also designed for breathability, so air moves through the mattress rather than heat building up around you.
What sizes does the Levisham 3750 come in?
Five UK sizes: Single, Double, King, Super King and Emperor. The Emperor option is handy for anyone wanting a genuinely oversized bed.
