Sleep Foundation's best overall and Tom's Guide's best for side sleepers: a pillow-topped hybrid with zoned lumbar coils, strong edges and plenty of hip and shoulder cushioning. But it's one of the priciest beds on these lists, the plush top can make it hard to move around on, and Tom's Guide says hot sleepers should pay for the cooling cover.
Top complaints
- Hard to move around on
Tom's Guide says the plush pillow top limited ease of movement for some testers. Sleep Foundation says this could be an issue for combination sleepers and people with mobility problems.
Source: Tom's Guide, Sleep Foundation - Hot sleepers need the cooling upgrade
Tom's Guide rated temperature 4/5 but says very hot sleepers should upgrade to the GlacioTex cool-touch cover or CoolForce layer.
Source: Tom's Guide - Expensive, with some bounce
Tom's Guide calls it 'a bona fide splurge' and the priciest mattress on its list (typically about $1,849-$1,918 for a queen). Motion isolation is mid-pack at 3.5/5, and Tom's Guide lists 'some bounce might be disruptive' as a con.
What owners love
- Cushioning for side sleepers
Tom's Guide scored pressure relief 4.5/5, second only to the Saatva, and says side and back sleepers on its panel found it comfortable.
Source: Tom's Guide - Strong edges and durability
Sleep Foundation rates edge support 9.5/10 and durability 8.5/10; Tom's Guide could comfortably sit on the sides (4/5).
