8cm comfort layer is deeper than standard Octaspring — more plush surface feel
200-night trial matches DreamCloud for the second longest reviewed
Dormeo's 20+ year European mattress engineering applied to their premium tier

£1,000+ for foam spring technology that remains less market-validated than pocket spring alternatives
Octaspring feel is still unfamiliar to those used to foam or spring — transition period expected
Dormeo's UK customer service is via European HQ — slightly slower than native UK brands

Leesa Original Foam Mattress (Double)

B-Corp certified — Leesa's social mission donates 1 mattress per 10 sold to shelters
LSA200 foam provides pressure relief with more responsive bounce than traditional memory foam
100-night trial with free collection maintains the category standard
10-year warranty from a B-Corp business prioritising customer trust
