The Good
(624 Mattress)

With two firmness options, the 624 caters for a wide range of sleepers. The medium firm option suits sleepers who want support and cushioning while they sleep. The medium soft option provides a plush, sinking into feeling. A specially designed fabric cover keeps you cool as you sleep, helped by the foam support layer that allows air to flow freely.

A custom feel is the biggest benefit of the Ecosa. It's rare to find an all-foam mattress that allows sleepers to swap layers for a softer or firmer feel. While this is a popular feature in hybrid designs, it's a unique touch for foam models. This makes Ecosa good for a variety of sleeping styles.

The Bad
(624 Mattress)

The 624 is averagely priced so it’s not the most affordable option out there. Unfortunately, we haven’t been able to find any independently verified reviews of the 624. This means we haven’t identified any customer complaints. The best way to understand if it’s right for you will be to take advantage of the 100-day trial.

(Ecosa Mattress)

Although the Ecosa mattress lets sleepers change the firmness, it's still too firm for some. A firm feel is good for side and back sleepers. However, small sleepers or stomach sleepers may find it too hard. Please note, as notified by the Ecosa team, recent upgrades to the comfort layer have targeted this issue, helping to make the mattress feel slightly softer.

As you have probably noticed, this article hasn’t been all about comparing mattresses. Yes, we have looked at the differences between both brands, but we haven’t forgotten to look at the overall mattresses. Now, let’s compare their features. At first glance, Ecosa mattress may seem to be slightly better. Their mattress is 7cm deeper, which may help you sleep more comfortably. However, the differences aren’t so significant. Another thing you will notice is that Ecosa’s cover is removable, while 624’s mattress isn’t. Therefore, if you want a washable cover, Ecosa is a better choice. 624 also costs less, so it may fit your budget better. However, the difference in price isn’t huge. We hope that this comparison was helpful. 624 vs. Ecosa, which one is better? Well, it all depends on your preferences. If you prefer 624’s cover, 624 is the better choice for you. If you prefer Ecosa’s mattress comfort, choose 624. Either way, you will like your mattress.
