How much weight does the Palace Mattress support?

It is not about knowing the maximum weight that this mattress supports without deforming, which is a lot, but rather the sleeper profile most compatible with this model. According to an internal study carried out at Colchón Exprés throughout 2019, 88.33% of our customers who purchased this model had a body mass index of less than 30. Therefore, this mattress is much more compatible with sleepers who are within this range, than those who have a higher BMI. If you don't know what your BMI is, you can find it out in our tool, in the item sheet

Can they leave it installed for me at home?

At Colchón Exprés, when you place your order for the Palace mattress, through one of our physical stores or through the website, you have the at-home installation service included in the price. This mattress is not delivered vacuum packed, so it takes up a large volume. In addition, it does not fit in most elevators and is heavy, even in individual sizes. So if you are a person who is not usually used to carrying this type of merchandise, take these factors into account when placing your order, wherever it may be.
