    • A bit firm for this side and stomach sleeper but still quite comfortable.
Size: Queen Style: 10” Memory Foam Pattern Name: Mattress
I bought two 10-inch memory foam mattresses from Amazon - one queen and one full. Ikea bedframes are the foundations for each. They're comfortable in the side and stomach sleeping positions even though they're on the firm side, at least for me because I'm tall - 6'4" and thin -160 pounds. Changing sleeping positions is relatively easy to do, however, I've noticed that this requires slightly more effort than with traditional 'bouncy' innerspring mattresses due to their minimal motion transfer. I'm hoping that these mattresses will remain completely flat in the unloaded state after hundreds of hours of use. And if so, will be excellent values for the price. ... show more

    • BEST budget gel mattress!
Size: Full Style: 10” Memory Foam Pattern Name: Mattress
My first Siena mattress did not fully expand along one edge and corners perhaps due to being boxed too long or other defects in the foam. I did give it a full week to do so and used a room heater at 72-75 degrees to encourage expansion. Amazon texting support helped me with scheduling the return pickup. The replacement mattress fully expanded within 2 hours. What a difference! I love that it completely supports me yet molds slightly to my body. It has a bit of an odor as it off gasses but nothing horrible and it goes away in a day or two. I really like that it is made without formaldehyde, etc! I do understand that it may not be good support or last long for someone who exceeds 250 pounds. I also found out it is made by Nectar. All in all, this gal is very pleased and sleeping well without joint pain. ... show more

    • Thank you!
Size: Twin Style: 10” Memory Foam Pattern Name: Mattress
I was skeptical at first because usually what can go wrong with a product is the experience I always have. Not this time, I followed the directions the mattress blew up almost instantly but not to full capacity. I went out and came back about 5 hours later and it was doubled in size, felt very firm to the touch I was so excited. I still waited a full 48 hours before using to ensure it had expanded to full capacity. Prior to use I woke up every morning with intense back aches. After the first night the next morning I woke with no back aches and enjoyed a full night sleep. I highly recommend this product and trust me I am hard to please. Great product, great price, easy set up. I just hope the mattress has sustainability. ... show more

    • A great value!
Size: Queen Style: 10” Memory Foam Pattern Name: Mattress
Very nice for the money, but firmer than I expected, although it’s still very comfortable. I bought it for a guest room and added a topper because it wasn’t quite as thick as I wanted. So far however my guests love it and get a good nights sleep!

    • That's night's sleep for couples who like different types of mattresses
Size: Queen Style: 10” Memory Foam Pattern Name: Mattress
My husband and I did not want to spend the money on a sleep number bed. So we decided to try this one instead. He likes a very fluffy and soft support. I however, prefer a firmer support and we both get what we need. The package came quickly and was very easy to open. One of the things we liked best about purchasing this without trying it. Beforehand was the return policy. But let's just say after one night on this mattress. There was no doubt we were keeping it. It has been over a year and we have still been very happy with our purchase. ... show more
