GoodBed Expert Review
Our Take on Serta iSeries Hybrid 1000 Medium (2021-2024)

Founder of GoodBed, Leading Mattress Expert
- Want a mattress with a medium amount of softness
- Are either a back or side sleeper, especially if you weigh 200 lb or less
- Can sometimes be disturbed by other movements in the bed (motion isolation is very good)
- Prefer a slightly above average amount of 'memory feel'
- Would like a mattress that performs very well when used with an adjustable base
- Enjoy sleeping just a bit more 'in' your mattress than 'on' it
- Like a little bounce in your mattress, but not much
- Are a stomach sleeper, especially if you weigh more than 250 lb
- Have a strong tendency to sleep hot (temperature regulation is pretty good, but not the best)
- Frequently sit or sleep along the edge of your bed (edge support isn't the best, but is still pretty good)
- Tend to have difficulty changing positions during the night (though ease of repositioning is still pretty good)
- Want a natural or organic mattress
