FAQs

Simba 1500

Can I clean my mattress?

Yes, you can clean your mattress using light fabric cleaning products or a soft, damp cloth. However, we do not recommend removing the cover.

Will I be able to get the mattress back in the box?

Once the mattress is out of the box, it cannot be put back inside. We also do not recommend attempting to fold or roll it as this may damage the spring layer inside.

Will my mattress have a smell when i first open it?

There might be a slightly unusual smell for the first few nights due to the fresh-out-of-the-box foam. However, this smell will fade away after a few days and will not return.
