The Dunlopillo Royal Sovereign is a mattress I like the idea of, mainly because Dunlopillo latex tends to have that springy, supportive feel without needing a big stack of layers. It is now sold as the Dunlopillo Elite Comfort 1400 Pocket Pillow Top. Before the rename, the Royal Sovereign was a medium-tension mattress with a latex core. The listing now shows 1400 pocket springs under a Talalay latex pillow top. It also has a hypoallergenic knitted cover to help keep you allergy free. This mattress now has an overall depth of 31cm and is suitable for all types of bed base, including divan beds.
Dunlopillo use only premium quality latex in their mattresses and pillows to give a luxurious feel and the support needed for a great night's sleep. A latex core bounces back quickly and stays properly resilient, not that slow, sinking memory foam feel. Owners describe the Royal Sovereign the same way: "Supportive yet not hard", one wrote, while another praised the "great pressure relief for my hip pain". On your back, latex at this tension should keep you nicely level, but I'd expect lighter side sleepers to find the Royal Sovereign's medium tension a touch firm around the shoulder because latex pushes back rather than letting you drop in. One owner found it firm enough to buy a topper after three weeks.
The Royal Sovereign used a soft quilted cover specially designed to provide pressure relief and comfort. One owner wrote that "It is soft to the touch but supports well when you lie down", which fits: it was not a thick, pillow-top style finish, so I wouldn't expect loads of initial squish before you hit the latex. Also worth saying, at 21cm it was on the slimmer side, which is fine on a supportive base but it could look a bit lean on deeper bed frames and it wouldn't give you that big, lofty 'hotel mattress' vibe.
The mattress includes pressure relief technology, a soft to medium tension and 31cm depth. The Dunlopillo Elite Comfort 1400 is designed to be hypoallergenic and is approved by the National Bed Federation. Guaranteed for 15 years.
For me personally, the Royal Sovereign sat in the good bracket if you like a cleaner, bouncier feel and you want something that stays supportive without loads of fuss. If you're after loads of sink-in softness, or you share a bed and are sensitive to movement, latex can feel a bit lively compared to a calmer pocket spring and foam combo, and at that sort of price I'd also have liked to see a bit more depth or a more substantial comfort layer.
