|---|---|---|
| Layers | AirTech® Comfort Layer, Unique Airflow System (Open Cell Foam), AirTech® Support Layer, Profiled Base Foam (3 Zones). | the floatfoam™ layer with active cooling, the memory layer with active cooling, the support layer, two foam casing layers (one each side of the springs), 1500 full-size pocket springs (12 cm). |
| Cover | The zip at the half way mark on the mattress allows for easy removal and wash of the top part of the cover, giving you a fresh sleep, night after night. We recommend washing the cover once a month at 40 degrees to get the best sleeping experience. | The quilted top cover is so soft and thick, it's almost cloud-like, and has small silver strands woven into it. This fancy technique makes it antimicrobial and antibacterial, but for extra freshness, you can unzip the cover and pop it in the wash. The white top panel of the mattress is 97% polyester, 2% elastane and 1% silver. |
| Machine-washable cover | No | No |
| Ergonomic handles | No | Yes |
| Comfort | The top AirTech® Comfort foam layer increases the cosiness of the mattress, giving the sleeper a great sleep, night after night. Manufactured in the UK, AirTech® foam is the very latest in memory foam technology, and is 30 times more breathable than some leading foam brands. This, and the memory foam's unique open cell technology, helps to promote air circulation, keeping your mattress fresh and keeps you cool and comfortable throughout the night. | Feeling too hot to sleep is a thing of the past with foams that actively cool you down. To have a good night's sleep, your temperature needs to be just right. So, we've added some clever technology to actively stop things from getting too hot and stuffy underneath the covers. We've infused tiny bits of graphite into the top two foams to pull excess heat away from your body. Springs are also naturally very airy and add a boost of breathability to the mattress - so you stay comfortably cool as can be. |
| Support | The OTTY Flex utilises our own AirTech® foam - an open cell foam which offers a perfect blend of comfort, breathability and support. The AirTech® Support layer helps to provide a great level of support. This helps to ensure the sleeper wakes up pain and niggle free. The pressure-relieving profiled base has three specially-designed zoning areas, which helps to improve comfortability. | Five layers of premium foam and one layer of 12 cm pocket springs provide your body with spine alignment and added pressure relief. The all-important top layer is a brand new type of foam giving you instant soothing pressure relief. Underneath three more luxurious layers of foam, you'll find the support of 1500 pocket springs. These adapt to your body's wriggles throughout the night, so your body wakes without aches. |
