A good night’s sleep starts long before you close your eyes. The mattress under you decides how well your back is supported, whether you wake up with sore shoulders and how much you feel your partner moving at night. Yet most people choose a mattress in a few minutes on a showroom floor. Understanding firmness and top styles makes the decision much easier, and that is exactly where full-size pillow top and euro top mattresses stand out: they add a comfort layer on top of a supportive spring core.
In this guide we explain how firmness and top styles work, then compare five full-size (135 x 190 cm) mattresses from soft to firm.
How to Choose the Right Firmness and Top
Firmness is personal, but your sleeping position is the best starting point:
- Side sleepers: usually prefer a soft or medium-firm feel that lets the shoulders and hips sink in slightly.
- Back sleepers: tend to do well on medium-firm mattresses that keep the spine aligned.
- Stomach sleepers and heavier bodies: often need a firm mattress so the hips do not sink too far.
- Pillow top vs euro top: a pillow top is a separate padded layer sewn on top, giving a plush first feel; a euro top is stitched flush with the sides, so it feels more even and holds its shape at the edges.
- Spring count and height: more springs generally mean more points of support, and a taller mattress usually has more comfort layers.
Keeping these points in mind makes comparing medium-firm and firm mattresses far less confusing.
Five Full-Size Mattresses From Soft to Firm
These models cover every firmness level and both top styles, and you can see all of them in this full-size mattress collection.
Therapedic Diamond
The Therapedic Diamond is the softest option on this list, with a plush pillow top and a generous 34 cm height. It is built on 660 springs and features Memory Carbon technology. It suits side sleepers and anyone who likes the feeling of sinking gently into the bed while still having a supportive spring base underneath.
Sealy Raissa
The Sealy Raissa offers a medium-firm feel with a euro top finish and 450 springs in a 30 cm profile. Its no-flip design means you never need to turn it over, and the fabric has an antibacterial treatment. It is a balanced choice for couples with different sleeping positions.
Restonic Nautic
The Restonic Nautic pairs a medium-firm euro top with 510 springs and an orthopedic design focused on posture support. At 28 cm high, it gives back sleepers and anyone who wakes up with stiffness a firmer base without feeling hard.
Spring Air Gran Atenas
The Spring Air Gran Atenas is a firm pillow top mattress with 510 springs and a 30 cm height. The pillow top softens the first contact, while the firm spring core keeps the body well supported. Its no-flip construction makes maintenance simple, and it suits back and stomach sleepers who want firm support with a comfortable surface.
Serta Dream Sheep
The Serta Dream Sheep combines a firm feel with a pillow top and 442 springs in a 30 cm profile. It is also a no-flip design, so the comfort layer always stays on top. It is a good fit for people who sleep on their stomach or back and prefer a supportive, stable surface.

Making Your New Mattress Last
A quality mattress can serve you well for many years with a little care. Use a breathable mattress protector to keep it clean, and place it on a solid base or box spring that matches its size. Even on no-flip models, rotating the mattress head to foot every few months helps it wear evenly. Air the bedroom regularly, avoid sitting on the same edge every day and give your body a couple of weeks to adjust to a new firmness before judging it.
Sleep Better, Starting Tonight
The right mattress depends on how you sleep and how firm you like your bed. The Therapedic Diamond offers plush comfort, the Sealy Raissa and Restonic Nautic deliver balanced medium-firm support, and the Spring Air Gran Atenas and Serta Dream Sheep give firm support with a comfortable top. Choose the one that fits your sleeping style from these full-size spring mattresses and enjoy more restful nights.
