Pros & Cons Side by Side

Dormeo Octaspring 6000 Mattress (Double)

Gen 8 Octaspring foam springs are the most advanced iteration — improved pressure relief and bounce
Zoned support system is firmer under hips and softer under shoulders for spine alignment
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

Koala Calm As Mattress (Double)

120-night trial — the longest single-period trial alongside DreamCloud reviewed
B-Corp certified — Koala's environmental and social standards verified by third-party assessment
Copper-infused open-cell foam provides antimicrobial properties alongside cooling
Australian design heritage applied to UK market — different design philosophy from UK brands
10-year warranty with B-Corp accountability for long-term quality commitment

Less brand recognition in UK vs Emma, Eve or Simba
Copper infusion adds cost without the temperature improvement of true airflow hybrids
Australian brand with UK fulfilment — customer service response from Australian headquarters
