„The spring count on a Sleepeezee label is the least useful number on it. Choose by the comfort layer, the firmness and whether you are prepared to turn the mattress every month.“
Look past the spring count
Sleepeezee names most of its mattresses after their spring count, and in this ranking that number runs from 1,000 in the Deluxe 1000 to 4,500 in the Centurial 01. More springs do not guarantee a better bed, and the 4,500-spring Memory Ultimate 4500 scores too low in our assessment to make this ranking. The layer between you and the springs does more to set the feel, whether that is wool and cashmere in the Wool Luxe 2800, alpaca wool in the Centurial 01, 20mm of Talalay latex in the Natural 2000, two layers of StayCool gel in the ActivFlex Response 3600, or plain white fibre in the Deluxe 1000. Where Sleepeezee quotes a spring count for a king, as it does for the two pillow tops, a double has fewer.

Firm is not automatically better for your back
Three models here carry a firm rating, the Ultimate Ortho 2000, the Luxury Ortho 1600 and the Deluxe 1000, and firm is often assumed to help a bad back. The best trial evidence points the other way. In a randomised, double-blind trial of 313 adults published in The Lancet in 2003, people with chronic low-back pain who slept on medium-firm mattresses reported less pain in bed and less disability after 90 days than those given firm ones, and the authors concluded that “A mattress of medium firmness improves pain and disability among patients with chronic non-specific low-back pain.” The NHS guidance on back pain advises staying active and does not recommend a mattress type. For most people that makes the medium-firm Natural 2000 or the medium Wool Luxe 2800, Centurial 01 and Jessica 1800 the safer starting point. The two medium-soft pillow tops, the ActivFlex Response 3600 and the Cool Refresh 3200, suit side sleepers, and the firm models suit back and front sleepers who already like a hard surface.
Decide whether you will turn it
The Wool Luxe 2800, the Luxury Ortho 1600 and the Deluxe 1000 are double-sided. Sleepeezee’s care advice is that “A double-sided mattress must be turned and rotated every week for the first three months and every month thereafter”, and a non-turn mattress is rotated head to foot on the same schedule (Sleepeezee FAQ). That matters most with the Wool Luxe 2800, which weighs 73kg in a king by Sleepeezee’s own table. The pillow tops are heavy too, 71kg for an ActivFlex king, but they are only ever rotated. Sleepeezee also says the upholstery settles into a natural body impression, which “is quite normal and not a fault”, so a shallow dip in the first months is not by itself grounds for a claim.
Where you buy sets the trial and the wait
Sleepeezee sells the models ranked here through retailers rather than direct, so the trial and the delivery date come from the shop. Mattress Online, which sells eight of the models ranked here, offers a 100-Night Comfort Trial that works as an exchange rather than a refund. You sleep on the mattress for at least 30 nights, you must have bought and used a Mattress Online protector, and a swap costs £49 (Mattress Online trial terms). Mattress Online lists these models as made to order, with lead times of two to four weeks. MattressNextDay offered the Natural 2000 for next-day delivery at the time of writing, but gives 14 days to start a return instead of a trial, and the Jessica Performance’s terms depend on the independent retailer that sells it. Our mattress protector comparison covers the protector that trial requires.

What British-made means here
Every Sleepeezee product is made at the company’s factory in Rochester, Kent, where it says more than 300 craftspeople work. The firm was founded in 1924 and was the first bed maker to receive a Royal Warrant from King Charles III (Sleepeezee company history, Royal Warrant Holders Association). It is also a member of the National Bed Federation, whose survey of 500 recent bed buyers found that 41% replaced their old mattress within five years and 46% spent no more than £399 on their new bed (NBF consumer survey, November 2021). At £402.53 for a double, the Deluxe 1000 is the only model here close to that budget.
