Product Care Instructions: In order to protect your mattress from stains and spills, we recommend using a mattress protector. This will also help with the overall health and lifespan of your mattress., To clean your mattress, we suggest applying baking soda to the soiled area and letting it stand for about 15 minutes. Then, vacuum and repeat as needed. It's important that you also air the product out as much as possible., We do not recommend applying liquids to the product. Applying liquids may stain the fabric and could potentially make the soiled area worse. Moisture or chemicals applied directly to the mattress can cause premature breakdown of the foam and damage the product.

  • As advised, definitely firm.
Style: Memory Foam Firm 12" Size: Queen
While it was easy to unpack and set up, it came with no directions or information on how long to let it breath before use.. After 12 hours the mattress head and foot were still half compressed. Been half a week now and I'm quite happy with the mattress. I've had 6 spinal surgeries and am a side sleeper and this mattress is quite comfortable for me. ... show more

  • Fine
Style: Memory Foam Firm 12" Size: Queen
Maybe a bit too firm and feels a bit smaller than we thought. It’s overall fine but we had to get a mattress pad because it was hurting my back.

Honestly loved it. We had a really old mattress from back in the day and this one is really a big change for us but so much more comfy

  • Firm and supportive and even better with a soft mattress topper
Style: Memory Foam Firm 12" Size: Queen
I love this mattress. I was going to buy a Nectar mattress but I had just moved and wanted next day delivery so I found this on Amazon. I added a soft gel mattress topper from the same brand on top and it’s like sinking into a very supportive cloud every night. No regrets on my mattress choice after 5 months. ... show more
