Best overall

This is the mattress I've owned for about two years now. It's designed from memory foam to relieve pressure on tired joints and comes with special AirFlow technology, which the brand says should keep you cooler while you sleep. It's got a medium firm build and comes with a 100-night risk-free trial. In the two years I've owned it, my mattress has not sagged or given way - it's still as supportive and comfortable as the first night I used it.

Sizes available: Twin to California King

Best for couples







Nectar's Hybrid Mattress combines gel memory foam and individually wrapped steel springs which the brand says combines breathability and support. You also get a 1-year sleep trial on this mattress, and it's built for couples who tend to move a lot throughout the night - so no matter which positions your partner shifts to, you won't be disturbed. It's also designed to relieve pressure points on your shoulders, legs and hips according to the brand.
