If you're in the market for a memory foam mattress, it's worth checking out this brand. They have a 90-night trial and 10-year limited warranty. They also offer white glove delivery service, which includes delivery and setup of your new mattress as well as removal of your old one. They offer an array of bases and frames, too.
The weightless select is a good choice for all sleep positions, but it's especially well-suited to back and stomach sleepers (as long as you pick their plush option). You'll get a great balance of cushioning firmness for your spine/back and contouring support for your hips and shoulders. This mattress does a decent job of supporting your neck and spinal alignment, too. The only downside is that it doesn't offer the same level of edge support as some of their other models.
Tempurpedic is the leader in premium and specialty sleep surfaces. It's known for its proprietary TEMPUR pressure-relieving material and makes mattresses, pillows, bed frames, and adjustable bases for home use. It also sells bedding products, including sheets, duvet covers, and blankets.
Tempurpedic offers seven different mattress choices with various add-ons and firmness options thrown in as well. These options are a mix of all-foam and hybrid constructed models. This includes the Adapt Series which combines a soft, TEMPUR comfort layer with their premium foam base and is sized for easy shipping. It's the only mattress from Tempur-Pedic that is delivered in a box.
