Find answers below.

Are Lull mattresses actually good?

Lull is an all-foam mattress type that offers good value for money. Since it's firm than standard mattresses, the lull is suitable for both stomach sleepers and back sleepers. This line of mattresses comes with a balanced foam feel that allows sleepers to sink slightly without getting stuck.

Does lull mattress come in a box?

All Lull mattresses are designed to be compressed and packed into a box roughly the size of a mini fridge and can be shipped to your doorstep for free.

How long before I can sleep on my lull mattress?

You will have to wait for about 24-48 hours for your new lull mattress to fully expand before you can sleep on it. However, sleeping on it before the 48 hours won't hinder the expansion process.

Can you flip a lull mattress?

It's not advisable to flip a Lull mattress. Its support layer is at the base. If you flip your mattress, you'd end up sleeping on an inflexible surface. Try to rotate your new mattes 180 degrees every six months or so to prevent wear.

    Worth It?

    We bought the Cal King after constantly being pushed off our Queen by our dog, now we all fit and sleep comfortably! Unboxing and expanding was quick and easy, we waited about 24 hours before laying on it and it's perfect!
