Final 2 today OTTY Hybrid charcoal bamboo, Hypnia Supreme

OTTY a very solid and reputable company.

I don’t much care about the supposed antimicrobial properties, but it’s only slightly more expensive than their midrange flagship model and is 6.5 (rather than 7/10) on their tension scale.

Medium-firm 25cm (quilted removable cover with 2cm of mem-foam, 2cm mem-foam, 2cm spring barrier “high density reflex foam”, 16cm pocket springs) foam edge walls and base.
100 day trial, full refund, no charge.
441.00.

French company, 4.2 Trustpilot reviews, but 15% 1 star & 20% <4.

Medium soft 30cm enclosed topper sewn to spring base
(trying to get more details than high density)
(Quilted cover, Mem-foam, Latex, honeycomb-foam, support-barrier foam, 20 cm "thick " pockets springs (420 in a single).

Told not to rotate, as 7 zoned.
200 day trial, full refund, no charge, 10% sinkage warranty.
360.00.

Hoping for abetter side-sleeping experience.

Basically, a solid above basic firmer hybrid with thinner layers,
or a tall “premium” model, that’s doubtlessly inflated price is currently slashed, but the company may have some QC and service issues.
Some talk of sagging/exceptional off-gassing, but their premium model may be safer and I don’t know if everyone would have followed the 2-3 day expansion instructions.
Either way, both have trial protection, as long as I can recognise defects in time.
