Flaxby Mattress Reviews 2026: Which Natural Model Is Best?

The Flaxby Natural range comes in three kinds

Judge a Flaxby by how it's built before you look at the fibre names. Two plain single-sided mattresses sit at the bottom of the price list, three Dual Season models turn over, and three pillow tops carry a fixed soft layer. All of them pair wool, flax and hemp with pocket springs, while the dearer ones add cashmere, mohair, alpaca, lambswool, silk or cotton.

The number in each name is the spring count for a king, so a double has fewer. On the flat models Dreams' layer diagrams describe micro pocket springs, with thicker Cortec springs round the edge. I treat the big numbers as a price ladder and judge the grade and whether it turns instead. Compare them with other natural mattresses before you fall for a number.

The Silkstone 13750 is the Flaxby I'd buy

The Silkstone leads the range because its money goes into what you lie on. You get lambswool on both faces, silk on one of them and ten natural fibres in all, tufted flat with no polyester layer in the stack. It's also the only Dual Season model sold softer than Firm, in Soft Medium or Medium Firm, which is where I'd start most side and back sleepers. As a side sleeper, I'd lie on the Medium Firm first.

At 34cm it wants deep fitted sheets, and at 66kg in a king it takes two people to turn. Dreams also sells this exact mattress with a removable cashmere pillow top as the 19750. A top you can lift off and air is a different thing from one sewn on for good.

For firm sleepers: the Flaxmoor 2500 or the Woolcroft 3500

These two share one build: the same nine layers, the same 28cm depth, the same British wool, Swaledale wool, flax and hemp over the same springs. For the extra money, the Woolcroft 3500 buys 1,000 more springs in a king and a grade one step softer: Firm against the Flaxmoor 2500's Very Firm. That's everything the money buys. Unless you want that touch of give, buy the Flaxmoor and keep the difference.

Both suit people who already know they like a firm bed, heavier back and front sleepers above all. If you sleep on your side and weigh under about nine stone, walk past both. Each has one sleeping side and an Eco polyester base layer under the natural fillings. At 28cm they're the shallowest in the range.

Dual Season Flaxbys: buy them for the turning

Dual Season means double-sided, which is the part I'd pay for. The Hempstead 5750, the Cashmere Vale 10750 and the Silkstone all turn over as well as rotate, which is how I'd always want a wool mattress made. The seasons I take more lightly. Dreams describes the Hempstead like this: "On one side, temperature regulating British wool feels oh-so cosy in colder weather. On the reverse, breathable cotton wicks away moisture to prevent overheating." Dreams' own layer diagram puts the same wool and cotton blends on both sides of the springs, so the published spec doesn't show a wool side and a cotton side.

The Hempstead and the Cashmere Vale come in Firm or Very Firm and nothing softer. To my mind the Cashmere Vale is the right build in the wrong firmness for most people: eight fibres, no polyester layer, tufted flat on both faces, and too firm for anyone who doesn't already sleep firm. Heavier back and front sleepers who want to turn their mattress should look at both. Everyone else wants the Silkstone. Dreams also sells the Cashmere Vale with a removable mohair pillow top, as the 15750.

The Flaxby pillow tops: judged one by one, picked by none

Three Flaxby Natural models have a fixed pillow top, and Dreams doesn't publish what's in any of the tops. I avoid sewn-on tops because the soft layer only goes one way, softer, and you can't turn the mattress to give it a rest. None of the three is a pick, though they aren't equally weak.

The Woolcroft Loft Pillow Top 4500 has a genuine niche: a lighter or side sleeper who wants a soft Harrison Spinks surface, in Soft Medium or Medium Firm, with a split option for couples. The Mohair Crest Pillow Top 6750 is the most mattress in the range for its price on paper, 34cm deep with three stacked spring layers. I'd still rather you spent the money on something you can turn. The Alpaca Moor Pillow Top 10750 is the softest Flaxby, sold in Soft or Medium, and the dearest single-sided one. Side sleepers drawn to it should try the Silkstone, which gets most of the way to that softness and turns over.

Where the Masters Guild and Oxtons Guild models went

The Masters Guild 3450, 4450, 8450 and the rest have gone from Dreams along with the Oxtons Guild. I lay on several of the old Masters Guild beds in Dreams and liked how cool the wool felt. The new range keeps the wool, hemp and flax.

A Firm 3450 buyer should look at the Woolcroft 3500, and a Medium 3450 buyer at the Silkstone 13750 in Medium Firm, because the Natural range has no plain single-sided Medium. The turnable 16150 maps onto the Silkstone too. The firm 8150, with its summer and winter sides, has its closest match in the Hempstead Dual Season 5750. Oxtons Guild and 10950 owners chose firm on a single-sided bed, which in the new range means the Flaxmoor 2500 or the Woolcroft 3500. The 4450, 8450 and 14950 pillow tops have pillow-top successors in the new range, though I'd still point you at the Silkstone.

Getting the base right under a heavy Flaxby

Check the weight before you put a Flaxby on an ottoman. Dreams recommends a combined mattress and bedding weight of 27kg to 65kg for the Flaxby Ottoman Divan (checked 5 November 2026). A Silkstone king weighs 66kg on its own. On a slatted frame, Harrison Spinks asks for gaps of no more than 75mm (3in) between slats. If a dip ever appears, check the slats before you blame the mattress.

The Flaxby Shallow Divan has a lower platform, which helps when half the range is 33cm or deeper. Sit on the edge before you buy: your feet should rest flat on the floor.
