I bought 2 Tomahawk Plush Euro Top Queen a month back for this same price while its was on the Thanksgiving deal. so far really its very good and suits for us. the quality of mattress really good as similar what you are seeing in the stores. i had lot of doubt and hesitation to ordering mattress online but i am happy now. no issues on Delivery and came within 2 weeks. i surprised only when i did not receive any email more than 2 days after ordering and thought US mattress scam. but it was instantly arrived and in the scam folder. but check the stores and find which one suits for you before ordering.. i see the specification are much similar only think they just change the name.
For example i tired this in Sleepys and ordered the same in USMattress.
