This mattress is composed of four different layers of memory foam and as such is geared towards delivering a sleep experience that combines body-relaxing comfort with strong back and joint support.
This specially designed mattress is available in three different firmness options: soft/plus, medium, and firm. The variation between these three options is pretty self-evident, and comes from the varieties of memory foam used.
The official Tulo website also has a interactive tool that can help you work out which variety of mattress (soft, medium, or firm) is best for you depending upon your own personal needs; they will assess your sleeping position (whether you’re a side sleeper, stomach sleeper, or back sleeper), any special sleep needs (if you tend to get overheated at night, experience lower back pain when lying down, if your limbs get numb or tingly when sleeping, et cetera), how large of a mattress you need, and so on in order to match you with the best mattress possible.
Generally, they recommend the soft mattress for side sleepers (since it puts less pressure on your shoulders and hips so that you can stay comfortable and pain-free when you sleep), the medium mattress for stomach sleepers (because it can offer comfort and support for your body without putting too much pressure on your stomach and internal organs), and the firm mattress for back sleeps (since it offers great levels of support for your back, shoulders, and other joints).
That being said, if you aren’t sure which level of firmness to try, you should consider the medium option since it combines firmness and comfort in equal amounts and can work well for side sleepers and back sleepers as well as stomach sleepers. Also, if you find that the mattress you picked isn’t the right firmness for your needs, you can contact the company and swap it out for a different mattress at no cost.
