Do not buy - the mattress we have has sags in parts and provides no support throughout the night after only 3 years. Sections are unsleepable on and if you do roll over into them in the night you wake up with hip / back ache as you’re just laying on compressed layers, so may as well sleep on the floor at that point.
Despite sending numerous photos it’s taken 3 months of their “claims department” stringing me along to begin legal action for a refund against the warranty.
Do not recommend.
